This standard describes the test method for the determination of type ⅰ interlaminar fracture toughness of fibrous metal laminates using single and double cantilever specimens, including test principle, equipment, sample preparation, condition adjustment, test process and analysis of results. It is suitable for the determination of type ⅰ interlaminar fracture toughness of fibrous metal laminates and composites, and the evaluation of their critical energy release rate and crazing expansion resistance. The standard provides a systematic guide for interlaminar fracture toughness testing, which is helpful for material performance evaluation and quality control.
