T/CSTM 01223-2024
Basic Information
Scope
Scope: This document specifies the method for determining the interlaminar fracture toughness (GIC) of pultruded plate composite components used in wind turbine blades using double cantilever beam (DCB) specimens. This document is applicable to the determination of interlaminar fracture toughness (GIC) of pultruded plate-pultruded plate composite components and pultruded plate-laminate composite components. The determination of interlaminar fracture toughness (GIC) of other types of composite components can also be used as a reference.
