摘　　要：冲压式剪切强度是玻璃纤维增强塑料重要的力学性能指标。探讨了GB/T 1450.2-2005和ASTM D732-2002两个标准之间的区别,并用相同纤维增强塑料样品进行冲压式剪切强度试验。对试验的结果进行了比较,发现采用ASTM标准方法试验结果的离散率相对较低。Shear strength by punch tool is an important mechanical property of FRP. The difference between GB/T 1450. 2-2005 and ASTM D 732-2002 was discussed, and the test results of the same FRP specimens by the two methods were also studied. It showed that dispersion rate of test result by ASTM D 732-2002 was lower than the other.
