The laminates of 6 different layers structure were designed and prepared
meanwhile the effects of the angle of different layer and different one-way zone volume mass fraction on the tensile properties of laminated plates were studied through the tensile test. The tensile ultimate strength
damage characteristics and load-displacement curves of 6 kinds of composite laminates under tensile test were obtained through experiments. The results show that the tensile strength of composite laminated plates decreases with the increase of eccentric axis angle. When the volume fraction of the 45° and 90° is the same
the tensile strength of the laminated plate in the 45° layer is higher than that of the laminated plate in the 90° layer. The delamination area can be effectively reduced on the surface of the [0°/45°] layer
and the layer is more prone to be layered because of the [0/90°] of internal shear. It is verified that the mechanical properties of composite laminated plates can be designed by changing the angle of lamination.
