الحل
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the amount of incompatible components added
الخلاصة الأساسية
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are the key
