Large Dimensional Change of CMC with Temperature
Sorun Belirtisi
Dimensions of CMC products change >2% in the range of -20 to 60°C
Neden Analizi
CMC thermal expansion coefficient is large; low crystallinity leads to high dimensional temperature sensitivity; no annealing treatment leaves residual stress
Çözüm
1)Add rigid filler to reduce thermal expansion coefficient; 2)Annealing treatment to stabilize dimensions; 3)Select high-crystallinity grade to reduce temperature sensitivity
Temel Çıkarım
Dimensional temperature sensitivity is caused by large thermal expansion coefficient; adding filler and annealing are the key
