ISO DIS 20975-2

Description / Abstract: This International Standard specifies the flexure test method for determining the throughthickness (out-of-plane) tensile properties of laminated carbon fibre-reinforced plastic (CFRP) composites, including strength, fracture strain, and modulus. This part of ISO XXXXX (this working draft) is applicable to laminated CFRP composites with unidirectional reinforced laminate, namely unidirectional CFRP (UD-CFRP). In addition, the calculation of effective volume is also described in this part of ISO XXXXX due to size effects of the through-thickness tensile strength.
