Insufficient Tensile Strength of CMC
Problembeschreibung
Tensile strength of CMC products is 15-20% lower than the standard value
Ursachenanalyse
CMC molecular weight is low and strength foundation is insufficient; filler interface is poor and does not play a reinforcing role; excessive orientation makes it strong longitudinally and weak transversely
Lösung
1)Select high-molecular-weight CMC grade; 2)Treat filler with coupling agent to improve interface; 3)Reduce orientation to reduce longitudinal-transverse differences
Wichtigste Erkenntnis
Insufficient tensile strength is caused by molecular weight and poor interface; selecting a high MW grade is the key
