Fiber-matrix interface moisture absorption causing performance deterioration
문제 현상
The mechanical properties of the product decline after long-term use in a humid environment
원인 분석
Microcracks at the fiber-matrix interface provide diffusion channels for water molecules; the hydrophilicity of the glass fiber itself promotes interfacial water penetration
해결 방법
Use silane coupling agents (such as KH-550/KH-570) to improve interfacial hydrophobicity; improve the compactness of interfacial bonding to reduce microcracks; perform sealing protection treatment on the product surface
핵심 요약
Water penetration along the interface is an accelerating factor of performance aging
