ASTM D790 未加强和加强塑料与电气绝缘材料的弯曲性能的标准试验方法

ASTM D790 Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials

ASTM D790 未加强和加强塑料与电气绝缘材料的弯曲性能的标准试验方法简介：ASTM D790应用于对未加强和加强塑料弯曲性能的测定，包括了高模量复合材料和电气绝缘材料。这种测试方法一般适用于刚性和半刚性材料。然而，对于那些应变极限在5.0%之内，但外表面不能被破坏或不能失效的产品，其抗弯强度是不能被确定的。这些测试方法利用三点加载系统广泛应用于简支梁。
