PI composite resin impregnation
ظاهرة المشكلة
When preparing PI prepreg, the resin insufficiently impregnates the fibers
تحليل الأسباب
PI precursor solution viscosity is high and does not easily penetrate fiber bundles; the fiber surface treatment is not compatible with the PI precursor
الحل
Reduce the viscosity and concentration of the precursor solution; select a fiber sizing agent compatible with PI; use solution impregnation or hot melt method
الخلاصة الأساسية
The quality of PI composites starts with the impregnation quality of the prepreg
