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。
ASTM D790 Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials scope:These test methods cover the determination of flexural properties of unreinforced and reinforced plastics, including
high-modulus composites and electrical insulating materials in the form of rectangular bars molded directly or cut from sheets, plates, or molded shapes. These test methods are generally applicable to both rigid and semirigid materials. However, flexural strength cannot be determined for those materials that do not break or that do not fail in the outer surface of the test specimen within the 5.0 % strain limit of these test methods.These test methods utilize a three-point loading system applied to a simply supported beam.
