Fibre-reinforced plastic compositess. Determination of laminate through-thickness properties. Determination of the elastic modulus, the strength and the Weibull size effects by flexural test of unidirectional laminate, for carbon-fibre based systems | Status: Current, Under review

1 Scope This document specifies a flexural test method for determining the through-thickness (out-of-plane) tensile properties of laminated carbon fibre-reinforced plastic (CFRP) composites, including strength, fracture strain, and modulus. This document is applicable to unidirectional CFRP (UD-CFRP) laminates. In addition, the calculation of effective volume is also described due to size effects of the through-thickness tensile strength.
