wet mechanical

The comprehensive tests of the mechanical properties showed that both the tensile strength at break and yield strength met the requirements of engineering plastics, and the Izod and Charpy impact strength in dry and wet state was obviously improved.

综合力学性能测试表明，材料的拉伸断裂和屈服强度符合工程塑料的要求，干态和湿态下的Izod、Charpy冲击强度得到显著提高，接近国外超韧聚酰胺66工程塑料水平。
