PI composite resin impregnation
문제 현상
When preparing PI prepreg, the resin insufficiently impregnates the fibers
원인 분석
PI precursor solution viscosity is high and does not easily penetrate fiber bundles; the fiber surface treatment is not compatible with the PI precursor
해결 방법
Reduce the viscosity and concentration of the precursor solution; select a fiber sizing agent compatible with PI; use solution impregnation or hot melt method
핵심 요약
The quality of PI composites starts with the impregnation quality of the prepreg
