在玻璃钢/复合材料的性能测试工作中,弯曲性能的测试工作量最多。其原因在于该试验方法简单易行,得出的综合性能有利于较快地对材料性能和制作工艺作出评价。然而,人们经常把它当作力学性能试验,在试验报告中仅给出二个指标,即弯曲强度和弯曲弹性模量,这远远没有完成弯曲测试这个工艺试验的任务。弯曲性能测试能提供的材料性能信息量是 In the performance test of FRP / composites, bending performance is the most demanding. The reason is that the test method is simple and easy to implement, and the comprehensive performance obtained is favorable for evaluating the material performance and the manufacturing process faster. However, people often think of it as a mechanical property test. Only two indexes are given in the test report, that is, bending strength and flexural modulus, which are far from the task of completing the bending test. Bending performance test can provide material performance information is
