Fiber-matrix interface moisture absorption causing performance deterioration
ظاهرة المشكلة
The mechanical properties of the product decline after long-term use in a humid environment
تحليل الأسباب
Microcracks at the fiber-matrix interface provide diffusion channels for water molecules; the hydrophilicity of the glass fiber itself promotes interfacial water penetration
الحل
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
الخلاصة الأساسية
Water penetration along the interface is an accelerating factor of performance aging
