Composites and advanced materials are changing industrial manufacturing
Why the materials conversation is changing
Composites and advanced materials are no longer treated simply as premium substitutes for metal. In more industrial applications, they are being assessed as system-level options for reducing weight, extending service life, improving corrosion resistance, supporting energy technologies and giving products a clearer end-of-life route.
The opportunity is real, but it is not evenly distributed. Market evidence from 2024 and 2025 shows growth in some global segments while European production volumes weakened, particularly in markets exposed to slower automotive, construction and infrastructure demand. For engineers, buyers and manufacturers, the practical question is not whether composites are “better,” but where their performance, processing route and circularity profile justify the cost and qualification effort.

What counts as composites and advanced materials
A composite combines two or more material phases so the finished material delivers properties that the separate ingredients cannot provide as effectively. In industrial composites, this usually means a reinforcement such as glass fiber, carbon fiber, natural fiber or aramid fiber embedded in a polymer, ceramic or metal matrix. Polymer matrix composites remain the largest and most visible group because they are used across transport, construction, energy, marine, electrical and consumer applications.
Advanced materials is a broader category. It includes high-performance composites, advanced alloys, ceramics, functional polymers, nanostructured materials, smart materials, coatings and materials engineered for thermal, electrical, structural or environmental performance. In practice, the overlap is substantial. Carbon fiber reinforced polymers, thermoplastic composites, ceramic matrix composites and recyclable resin systems are both composites and advanced materials when they solve a demanding design problem.
This distinction matters because the buying decision changes. Commodity materials are typically selected on price, availability and basic properties. Advanced materials require a wider assessment of performance, manufacturability, lifecycle impact, reliability, regulation and supply-chain risk.
The market signal is mixed, not uniformly bullish
Recent public data explains why the industry conversation has become more cautious. AVK’s 2025 report on the European composites market estimated the global composites market at 13.5 million tonnes in 2024, up from 13 million tonnes in 2023. Europe moved in the opposite direction: production volume fell 5.6% in 2024 to 2,416 kilotonnes, compared with 2,559 kilotonnes in 2023. The contrast suggests that demand is shifting by region and application rather than expanding evenly across all markets.
The same AVK report shows how strongly application mix shapes demand. In Europe, transport accounted for nearly half of total composites production by volume in 2024. Electrical and electronics represented about one fifth, and construction and infrastructure just under one fifth. When automotive and building activity slows, the effect on composites is immediate. This is why a material family with strong long-term technical value can still face short-term volume pressure.
Thermoplastics are one of the clearest structural shifts. AVK reported European thermoplastic composites at 1,368 kilotonnes in 2024, down from 1,423 kilotonnes in 2023, yet their share of the total European market rose to 58.2%. Thermoset composites, excluding carbon fiber reinforced plastics, fell to 983 kilotonnes and represented 41.8% of the market. This does not mean thermosets are disappearing; they remain critical in many structural applications. It does show that thermoplastics are gaining attention because, in selected applications, they can offer shorter cycle times, weldability, toughness and a more direct route to remelting or reprocessing.
| Market signal | What it suggests | Why it matters |
|---|---|---|
| Global composites volume grew in 2024 while Europe declined | Growth is regional and application-specific | Suppliers need to track end-market exposure, not only headline demand |
| Transport remains the largest European application by volume | Automotive and commercial vehicle cycles heavily influence demand | Lightweighting opportunities depend on cost, production rate and qualification |
| Thermoplastics increased share despite lower absolute volume | Processing and recyclability are becoming strategic criteria | Material selection is shifting from properties alone to production and lifecycle fit |
| Short glass fiber reinforced thermoplastics dominate thermoplastic volume | High-volume composites are not only aerospace-grade carbon fiber parts | Industrial adoption often starts with practical, moldable, cost-sensitive materials |
Where adoption is strongest
The strongest opportunities for composites and advanced materials are concentrated in applications where several benefits overlap. A lighter part is useful. A lighter part that also resists corrosion, reduces assembly complexity, integrates functions and performs in harsh service conditions is more compelling.
Transportation and electric mobility
Vehicle lightweighting remains a major driver. The U.S. Department of Energy states that a 10% reduction in vehicle weight can improve fuel economy by 6% to 8%, and that replacing heavier steel components with high-strength steel, aluminum or glass fiber reinforced polymer composites can reduce component weight by 10% to 60% in the short term. For electric vehicles, weight reduction can help offset battery mass, improve range or allow smaller battery packs for the same range target.
The main barrier is production economics. Automotive parts require high repeatability, fast cycle times, crash performance, joining compatibility, paint and surface quality, and predictable repair routes. This is why glass fiber thermoplastics, sheet molding compounds and tailored continuous fiber reinforcements may coexist rather than one material replacing the others.
Aerospace, defense and advanced air mobility
Aerospace has long used carbon fiber composites because weight savings translate into fuel efficiency, payload and range. Newer opportunities include eVTOL aircraft, drones and next-generation narrow-body aircraft, which ACMA’s 2026 State of the Industry Report identified among future high-growth applications. Qualification cycles are long, so adoption is slower than material headlines often imply. The technical logic remains strong where stiffness-to-weight and fatigue performance are decisive.
Wind energy and hydrogen storage
Wind turbine blades, hydrogen pressure vessels and related energy infrastructure are natural fits for composites because they demand high strength at low weight. Blades must survive decades of cyclic loading, moisture, temperature changes and repair constraints. Hydrogen vessels require high pressure capability with strict safety and fatigue requirements. ACMA’s 2026 report highlighted wind energy and hydrogen pressure vessels among areas expected to support future composite demand.
Construction, infrastructure and electrical systems
Infrastructure is less visible than aerospace, but it is a major industrial market. Composite rebar, bridge components, utility poles, tanks, pipes, panels and profiles can offer corrosion resistance and lower maintenance needs. Electrical and electronics applications use composites for insulation, housings, structural support and environmental protection. Adoption depends heavily on codes, installer familiarity, fire performance, long-term durability evidence and lifecycle cost calculations. See also: Application.
From lightweighting to circular design
The most important change in the sector is the move from performance-only thinking to circular design. Traditional thermoset composites are durable because their polymer networks are cross-linked. The same chemistry makes them difficult to remelt and recycle. Mechanical recycling, pyrolysis and solvolysis can recover value, but each route has trade-offs in fiber quality, cost, energy use, contamination tolerance and available outlets for recovered material.
Research is moving in two directions. One path improves end-of-life treatment for existing thermoset waste. The other designs new resins and matrices so recycling is considered from the start. NREL’s August 22, 2024 announcement on its PECAN resin is a useful example. Researchers built a 9-meter wind blade prototype using a biomass-derivable resin and reported that the material could be chemically recycled, with the prototype blade broken down in six hours under the demonstrated process. NREL also emphasized that the resin performed on par with the current thermoset blade standard in the reported testing and could be made using a timeframe similar to existing blade cure cycles.
That is promising, but it should not be overstated. A 9-meter prototype is not the same as full commercial deployment across 60-, 80- or 100-meter blades. Larger structures introduce certification, field repair, weathering, cost and supply-chain questions. The value of the example is that it shows where the industry is moving: recyclable-by-design systems that try to preserve structural performance while reducing end-of-life friction.
Manufacturing is becoming the real battleground
Material properties draw attention, but manufacturing determines adoption. Many advanced composites show excellent lab performance yet achieve limited industrial penetration because they are too slow, too costly or too difficult to inspect at scale. The next stage of competition is therefore less about inventing a stronger fiber and more about producing consistent parts with lower scrap, shorter cycles and verifiable quality.
Thermoplastic composites are attractive in this context because they can support welding, stamping, overmolding and faster forming in selected applications. Continuous fiber thermoplastics remain a smaller niche by volume, but they are strategically important where strength, toughness and process speed can be combined. Short glass fiber reinforced thermoplastics dominate European thermoplastic composite volume because they work with established molding infrastructure and serve high-volume applications.
Automation also matters. Automated fiber placement, filament winding, pultrusion, resin transfer molding, compression molding and additive-compression hybrid routes all aim to control fiber architecture, reduce labor intensity and improve repeatability. Digital process monitoring is becoming more important because composite defects can be internal, subtle and expensive to find late. For structural applications, quality assurance is not an optional inspection step; it is part of the material system.
How decision makers should evaluate material choices
Choosing composites and advanced materials requires a broader checklist than comparing tensile strength or density. A technically superior material can fail commercially if it lacks a reliable processing route, repair method, recycling outlet or qualified supply base. Conversely, a less exotic material may win if it meets enough performance requirements while fitting existing equipment and cost targets.
- Define the main design constraint. Is the part limited by weight, stiffness, corrosion, fatigue, thermal behavior, electrical insulation, fire performance or assembly complexity?
- Compare lifecycle cost, not only purchase price. Composites may cost more upfront but reduce maintenance, coating, replacement or transportation costs in selected applications.
- Check production rate early. A material suitable for aerospace volumes may not suit automotive cycle times or infrastructure budgets.
- Plan joining and repair. Bolting, bonding, welding and hybrid metal-composite joints all affect durability and inspection.
- Assess end-of-life routes before launch. Mechanical recycling, reuse, chemical recycling or energy recovery should be evaluated before parts enter the field.
- Confirm standards and qualification needs. Pressure vessels, aircraft parts, building products and electrical systems may require different test evidence and certification pathways.
The practical future of composites will be shaped by these trade-offs. The industry is unlikely to move in a straight line from metals to composites or from thermosets to thermoplastics. Manufacturers are more likely to use hybrid structures, local reinforcement, recyclable resin systems, lower-cost fibers and more automated processing to apply advanced materials where they create measurable value.
Frequently asked questions
Are composites always lighter than metals?
Often, but not always in a finished system. A composite part can reduce weight significantly when its fiber architecture, wall thickness, joining method and load path are optimized. If the design simply copies a metal part, the weight saving may be smaller and the cost may be harder to justify.
Are thermoplastic composites more recyclable than thermoset composites?
Thermoplastic composites can be easier to reprocess because the matrix can soften or melt under heat, but recyclability still depends on fiber type, additives, contamination, part size and whether there is a market for the recovered material. Thermoset recycling is improving through mechanical, thermal and chemical routes, but it remains more complex.
Why are carbon fiber composites not used everywhere?
Carbon fiber composites offer excellent stiffness-to-weight and strength-to-weight performance, but they are expensive, energy-intensive to produce, sensitive to manufacturing quality and often require demanding inspection and qualification. Glass fiber, natural fiber, metals or hybrid structures may be more appropriate when cost or volume is the main constraint.
What is the most important trend for industrial users?
The most important trend is the connection between performance and lifecycle design. Buyers are asking not only whether a material is strong and light, but also whether it can be produced at scale, repaired, documented, recycled and justified under changing environmental and supply-chain expectations.
