| 摘 要： | 为了探究三维间隔纬编织物中连接纱对其增强复合材料性能的影响,以玻璃纤维为原料,在自主开发的新型三维间隔纬编针织机上通过喂入与不喂入连接纱,制得有无连接纱的两种增强体,利用真空辅助转移模塑工艺VARTM(Vacuum Assistant Resin Transferring Molding)加工成复合材料.对这两种复合材料进行了三点弯曲和霍普金森(Hopkinson)压杆冲击测试.实验表明,连接纱明显地提高了复合材料的抗弯曲性能和抗冲击性能.

| Abstract: | In order to assess the influence of the connecting yarns for the composite reinforced by the three-dimensional spacer weft-knitted fabric manufactured on an improved three-dimensional spacer weft knitting machine,both kinds of the fabrics with and without connecting yarns were fabricated by enabling and disabling the connecting yarn feeding system. The fabrics were employed as reinforcements to make composites through the VARTM(Vacuum Assistant Resin Transferring Molding) method. The 3-point bending and Hop... |
