介绍了Z-pin在无人复合材料壁板中的应用及复合材料Z-pin的拉挤工艺,利用热压罐和真空袋压整体Z-pin嵌入工艺,在无人机复合材料层板、板筋结构件、复合材料胶接连接件及泡沫夹层中的应用。对于板件在保持面内抗拉强度的同时,提高无人机复合材料壁板的层间断裂韧性及损伤容限,有效改善了复合材料蒙皮的抗冲击性能。 This paper introduces the application of Z-pin in the unmanned composite wallboard and the pultrusion technology of composite Z-pin. By using the Z-pin embedding process of autoclave and vacuum bag, Slab structural parts, composite materials, plastic connectors and foam sandwich in the application. As to the tensile strength of the panel while maintaining the in-plane tensile strength, the interlaminar fracture toughness and damage tolerance of the UAV composite panel are improved, and the impact resistance of the composite skin is effectively improved.
