Abstract

Stacking plates of CFRP composite materials are increasingly used because of their unique characteristics. However, unlike other materials used in metallurgy they have a disadvantage of uneven quality and anisotropy when combined with other composites. Hence, specimens of CFRP stacking plates are manufactured by changing orientation angles throughout three quasi-isotropic plies (0°/45°/90°/−45°)6 s , (03°/453°/903°/−453°)2 s , and (06°/456°/906°/−456°) s and throughout three cross plies (0°/90°/0°/90°)6 s ,(03°/903°/03 °/903°)2s, and (06°/906°/06°/906°) s . In this study 3-point bending tests and transverse bending tests have been carried out in order to find out mechanical characteristics according to orientation angles by stacking in 6 different types along with the change of stacking composition method of a CFRP composite.
