The Hidden Gap in ISO 527-4: Why Moisture Absorption Testing Matters for GFRP
Subtitle: Addressing Uncovered Standards with Advanced Testing Techniques

开头:
Imagine designing a high-performance glass fiber-reinforced plastic (GFRP) component for aerospace or automotive use, only to discover it fails prematurely due to unnoticed moisture absorption. This is the real-world gap left by ISO 527-4—a critical standard for tensile testing that doesn’t explicitly cover moisture absorption rates. Why does this matter, and how can industries bridge this gap?
为什么吸湿率测试被忽视?
Why Is Moisture Absorption Overlooked?
ISO 527-4:2021 (Plastics—Determination of tensile properties—Part 4: Test conditions for isotropic and orthotropic fiber-reinforced plastic composites) focuses on mechanical properties like tensile strength and modulus. However, 吸湿率(moisture absorption)—a key factor affecting GFRP’s long-term performance—isn’t addressed.
