Glass fiber reinforced plastic severe floating fiber
문제 현상
Glass fiber reinforced injection molded product surface has exposed glass fiber, rough and prickly to hand
원인 분석
Poor interfacial bonding between glass fiber and matrix pushes to surface, floating fiber phenomenon; injection speed too fast, glass fiber oriented at surface
해결 방법
1) Treat glass fiber with silane coupling agent KH-570 0.5-1wt% to improve interface; 2) add matrix-g-MAH 2-3wt% to strengthen interface and promote encapsulation; 3) reduce injection speed to reduce floating fiber; 4) mold temperature 50-60°C to improve surface encapsulation; 5) glass fiber length 0.5-1mm to reduce floating fiber
핵심 요약
Floating fiber is caused by poor interface and injection orientation; coupling agent and reduced injection speed are key
