Fiber volume fraction in composite materials and its role in testing
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…
What void content means in materials testing and why it matters
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.
How Does Void Content Affect Composite Material Testing and Buyer Decisions
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.
