Internal Delamination Cracking of CMC
Problem Phenomenon
CMC products delaminate internally and crack along the interface
Cause Analysis
Interfacial adhesion between CMC and incompatible fillers or blend components is poor; cooling shrinkage differences cause interlayer stress
Solution
1)Use compatibilizer to improve interfacial adhesion; 2)Uniform cooling to reduce interlayer stress; 3)Reduce the addition of incompatible components
Key Takeaway
Internal delamination is caused by poor interface and shrinkage differences; compatibilizer and uniform cooling are the key
