ABSTRACT The improvement of interlaminar properties of epoxy matrix composites mainly includes toughening of resin matrix and design of interlaminar structure. The toughening of resin matrix includes filler， film and deposition， and the interlayer structure design includes 3D braiding， stitching and Z-pinning technology. In this paper， two methods for improving interlaminar properties of composites are introduced.
