ActiveTest method for mode Ⅱ interlaminar fracture toughness of carbon fiber reinforced composite materials—Three point bending method with end notched
碳纤维增强复合材料Ⅱ型层间断裂韧性的测定 端部切口三点弯曲法
Application Summary AI generated
This standard specifies the test method for determining Mode II interlaminar fracture toughness of carbon fiber reinforced composite materials using the end-notched three-point bending method. It is applied in the aerospace, automotive, and wind energy industries to evaluate the resistance of laminated composites to shear-driven delamination under in-plane loading conditions. The standard is used during material qualification, quality control, and structural design verification for composite components.
