Excessive porosity in carbon fiber composite materials
ظاهرة المشكلة
The internal porosity of the product is >2% and performance does not meet standards
تحليل الأسباب
The resin does not fully wet the fibers and air is entrained; volatiles are not discharged during curing; molding pressure is insufficient
الحل
Optimize the resin wetting process (such as vacuum-assisted RTM); extend vacuuming time and pressure; add defoamers to the resin system
الخلاصة الأساسية
Porosity is the core indicator of carbon fiber composite quality control
