Scope
This document describes the principle, instrumentation, samples, conditioning and testing environment, testing procedures, result calculation, and test report of determining the fracture toughness of carbon fiber reinforced composites between Type I and Type II interlayers using the double cantilever beam asymmetric bending method.
This document is applicable to the determination of the fracture toughness between Type I and Type II interlayers of unidirectional laminates of carbon fiber reinforced composites under static loading. The determination of the fracture toughness between interlayers of other fiber reinforced composites can be used as a reference.
