Internal Delamination Cracking of CMC

Fenómeno do problema

CMC products delaminate internally and crack along the interface

Análise das causas

Interfacial adhesion between CMC and incompatible fillers or blend components is poor; cooling shrinkage differences cause interlayer stress

Solução

1)Use compatibilizer to improve interfacial adhesion; 2)Uniform cooling to reduce interlayer stress; 3)Reduce the addition of incompatible components

Conclusão principal

Internal delamination is caused by poor interface and shrinkage differences; compatibilizer and uniform cooling are the key
