1 Scope

This document describes the determination of through-thickness (out-of-plane) tensile strength, tensile rupture

Flexural Test Method for Bad Strain and Tensile Modulus.

This document applies to carbon fiber reinforced plastic composite unidirectional (UD-CFRP) laminates. In addition, due to the existence of tensile strength in the thickness direction

In the size effect, the calculation of the effective volume is also described.
