Severe Excessive Orientation of CMC
Fenómeno do problema
Longitudinal-transverse property difference of CMC products >50%, excessive orientation
Análise das causas
Injection speed is too fast and molecular chains are highly oriented in the flow direction; gate design causes unidirectional flow
Solução
1)Reduce injection speed to reduce orientation; 2)Multi-point gates to reduce unidirectional flow; 3)Annealing treatment to partially release orientation
Conclusão principal
Excessive orientation is caused by fast unidirectional flow; speed reduction and multi-point gates are the key
