Large EAA dimensional change with temperature
Sorun Belirtisi
EAA product dimensions change >2% within the range of -20 to 60°C
Neden Analizi
EAA thermal expansion coefficient large; crystallinity too low causing high temperature sensitivity of dimensions; no annealing treatment, residual stress present
Çözüm
1) Add rigid filler to reduce thermal expansion coefficient; 2) Anneal 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 is key
