UpcomingTest method for mixed mode Ⅰ-mode Ⅱ interlaminar fracture toughness of carbon fiber reinforced composites—Double cantilever beam-uneven bending moment
碳纤维增强复合材料Ⅰ型-Ⅱ型混合层间断裂韧性的测定 双悬臂梁非对称弯曲法
Application Summary AI generated
This standard specifies a test method for measuring the interlaminar fracture toughness of carbon fiber reinforced composites under combined Mode I (opening) and Mode II (shearing) loads using a double cantilever beam with uneven bending moments. It is applied in the aerospace, automotive, and wind energy industries to evaluate the delamination resistance of composite laminates under mixed-mode loading conditions. The method is critical for material qualification, structural design validation, and quality control of high-performance composite components.
