GB/T 41501-2022 Fibre-reinforced plastic composites—Determination of interlaminar strength and modulus by double beam shear test

Scope: This document specifies the determination of interlaminar shear strength and interlaminar shear modulus of fiber reinforced plastic composites by the double beam method (DBS). This document applies to glass fiber or carbon fiber reinforced thermoset plastic composites capable of acceptable interlaminar shear failure. This document applies only to laminates with symmetrical and balanced layups to avoid test results being affected by bending/torsion or bending/tension coupled deformations (see 6.2). This document is especially applicable to unidirectional laminates in which the fibers are aligned along the length of the specimen (axial).
