摘　　要：详细阐述三维正交机织物的结构特征、织造原理及织造工艺,以三维正交机织物为增强体、环氧树脂为基体,采用真空辅助树脂传递模塑(VARTM)工艺成型,制成复合材料,并分析其内部结构。结果表明:由普通织机改造的多综眼多剑杆织机可以织造三维正交机织物,成型后复合材料内的纱线形状和位置未发生明显变化,树脂较好地渗透到织物内部,复合材料具有较高的纤维体积分数。研究结果为进一步研究三维正交机织复合材料的力学性能及应用奠定了基础。Structure characteristic,weaving principle and process of 3D orthogonal woven fabrics were introduced in detail. By means of the vacuum assisted resin transfer molding（ VARTM）process,the composite material was manufactured with 3D orthogonal woven fabric as reinforcement and epoxy resin as matix. The inner structure of the composite material was analyzed. The results showed that 3D orthogonal woven fabric could be produced by a multi-heard and multi-projectile loom reformed from a normal loom. The shape and location of yarn in the composite material did not changed,and the resin penetrated well into the fabric. The composite material had a higher fiber volume fraction. These results had put a foundation for further investigation on mechanical performance and application of 3D orthogonal woven fabric composite.
