Application Summary AI generated

This standard specifies a test method for determining the onset of mode I fatigue delamination growth in fiber-reinforced plastic composites. It is applied in the aerospace, automotive, and wind energy industries to evaluate the durability and damage tolerance of composite laminates under cyclic loading. The method is used during material qualification and quality control to assess the resistance of composite structures to interlaminar crack initiation.
