Carbon Fiber & Composites Guide | Specs, Process & Use
A tensile test for composite materials measures direction-specific strength, strain and modulus from a controlled coupon pull. This article explains method selection, specimen control, reporting requirements and key interpretation limits for polymer matrix composites.
Composite parts need inspection methods that account for anisotropic fiber architecture, hidden bond lines, thickness changes, and service damage. This article compares the main NDT options for composites and explains how engineers match inspection…
A practical guide to selecting nondestructive testing methods for composite materials based on defect type, structure, access, production stage and inspection limits.
CFRP tensile strength varies with fiber grade, laminate direction, resin system, fiber volume and test method. This article explains how to read published values and test reports without treating one number as universal.
ASTM D3039 specimen size depends on laminate type, fiber orientation, tab design, and gripping method. This guide summarizes common coupon dimensions and the practical limits behind them.
Fiber volume fraction is a core quality metric for composite materials because it connects material design, process control, density, void content and mechanical performance. This article explains what Vf means, how it is calculated…
Void content is a practical quality indicator for composites, reinforced plastics, porous materials and additively manufactured parts. This article explains how it is measured, what the numbers mean, and why method selection matters.
Void content can change composite strength, service life, inspection results, and batch approval. This guide explains common test methods and what buyers should check before accepting material.
A shop-floor guide to choosing an NDT method for composite parts, including ultrasonic C-scan, thermography, shearography, and X-ray CT. Match the method to the defect, material, standard, and inspection target before production or shipment.
ASTM D3039 testing is used to check tensile strength, modulus, strain, and failure behavior in polymer matrix composites. This guide explains the test steps, specimen notes, report items, and how buyers use the data…
