Internal Delamination Cracking of CMC
Fenómeno del problema
CMC products delaminate internally and crack along the interface
Análisis de la causa
Interfacial adhesion between CMC and incompatible fillers or blend components is poor; cooling shrinkage differences cause interlayer stress
Solución
1)Use compatibilizer to improve interfacial adhesion; 2)Uniform cooling to reduce interlayer stress; 3)Reduce the addition of incompatible components
Conclusión clave
Internal delamination is caused by poor interface and shrinkage differences; compatibilizer and uniform cooling are the key
