A processing method for composite laminates with intersection ply mode was putted out in this paper based on automated fiber placement (AFP) technology.The samples of the composite laminates were prepared,including crossing,crossing intersection ply laminates and traditional,two-direction intersection,four-direction intersection ply quasi-isotropic laminates.Then,the laminate mode and mechanical properties of the composites were studied by mechanical properties testing,microscopy and ultrasonic testing (UT).The results show that the tensile, compressive,and flexural properties of crossing intersection ply laminates are lower than traditional,but the interlaminar shear strength is increased by 16%.With the deepening of intersection,the tensile properties are weaker.The open hole tension,compression and compressive residual strength after impact(CAI) residual ratio of quasi-isotropic intersection ply laminates is higher than traditional.Intersection ply laminates have higher damage tolerance than normal ply laminates.
