ASTM D790 未加強和加強塑膠與電氣絕緣材料的彎曲性能的標準試驗方法
ASTM D790 Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials
ASTM D790 未加強和加強塑膠與電氣絕緣材料的彎曲性能的標準試驗方法簡介：ASTM D790套用於對未加強和加強塑膠彎曲性能的測定，包括了高模量複合材料和電氣絕緣材料。這種測試方法一般適用於剛性和半剛性材料。然而，對於那些應變極限在5.0%之內，但外表面不能被破壞或不能失效的產品，其抗彎強度是不能被確定的。這些測試方法利用三點載入系統廣泛套用於簡支梁。
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.
