Uneven dispersion of carbon fiber in resin
문제 현상
Chopped carbon fibers agglomerate in the resin and cannot be dispersed
원인 분석
Carbon fiber has a large specific surface area and easily agglomerates electrostatically; fibers physically entangle with each other; mixing shear force is insufficient to open the agglomerates
해결 방법
Use coupling agents and surface treatment to reduce inter-fiber friction; extend mixing time and provide sufficient shear force; consider using carbon fiber masterbatch
핵심 요약
Good dispersion of carbon fiber is the prerequisite for fully exerting the reinforcement effect
