Internal Delamination Cracking of CMC

Problembeschreibung

CMC products delaminate internally and crack along the interface

Ursachenanalyse

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

Lösung

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

Wichtigste Erkenntnis

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