摘要
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 quasiisotropic plies (0°/45°/90°/-45°)68, (03°/453°/903°/-453°)2s, and (06°/456°/906°/-456°)s and throughout three cross plies (0°/90°/0°/90°)68, (03 °/903 °/03°/903°)2s, and (06 °/906 °/06°/906°)8 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.
