ActiveFibre-reinforced plastic composites—Determination of the mode Ⅱ fracture resistanc for unidirectionally reinforced materials using the calibrated end-loaded split(C-ELS) test and an effective crack length approach
纤维增强塑料复合材料 用校准端载荷分裂试验（C-ELS）和有效裂纹长度法测定单向增强材料的Ⅱ型断裂韧性
Application Summary AI generated
This standard specifies a test method for measuring the Mode II interlaminar fracture toughness of unidirectional fibre-reinforced plastic composites. It is applied in materials research and quality control within the aerospace, automotive, and wind energy industries to evaluate resistance to delamination under shear loading. The calibrated end-loaded split (C-ELS) test with an effective crack length approach is used specifically for composites with continuous fibre reinforcement in a single orientation.
