Through-the-thickenss tensile strength testing using a curved beam
The in-plane strength properties of a composite material, axial and transverse tension and compression and in-plane shear, are usually the first to be considered in design. However, through-the-thickness (interlaminar) strength properties cannot be ignored. Through-the-thickness tensile strength, in particular, can be critical to structural performance.
