【摘要】：采用手糊成型制备了双夹层三维中空夹层复合材料,重点研究了厚度为5 mm和8 mm的三维中空织物ZK5和ZK8铺层顺序对复合材料压缩强度的影响,并从树脂含量、织物厚度匹配性角度进行分析。结果表明,随树脂含量增加,三维中空夹层复合材料的压缩强度明显提高;双夹层三维中空夹层复合材料中,下层的树脂含量明显高于上层;ZK5和ZK8织物铺层顺序对双夹层中空复合材料的压缩强度影响较大,其中将ZK8置于ZK5下层时复合材料的压缩强度为ZK8置于ZK5上层时的1.7倍,即在三维中空夹层复合材料总厚度不变的情况下,将高厚度中空织物置于下层的结构明显优于将其置于上层的结构。通过这一概念可以在保证三维中空夹层复合材料整体厚度尺寸不变、质量不增加的条件下通过铺层结构的匹配设计,最大限度地提高复合材料的力学性能。
[Abstract]:Two-sandwich three-dimensional hollow sandwich composites were prepared by hand paste molding. The effects of ZK5 and ZK8 laying sequence on the compressive strength of the composites were studied, and the resin content was used to study the effects of ZK5 and ZK8 layers on the compressive strength of the composites. The matching angle of fabric thickness is analyzed. The results show that with the increase of resin content, the compression strength of 3D hollow sandwich composites is obviously increased, The resin content of the lower layer is obviously higher than that of the upper layer ZK5 and ZK8 fabric layer, and the compression strength of the composite is 1.7 times that of the ZK8 when ZK8 is placed in the ZK5 lower layer, and the compressive strength of the composite is 1.7 times that of ZK8 when ZK8 is placed in the upper layer of ZK5. When the total thickness of three-dimensional hollow sandwich composites is constant, the structure of high thickness hollow fabric placed in the lower layer is obviously better than that of the upper layer. Through this concept, the mechanical properties of the composite can be greatly improved by the matching design of the layer structure under the condition that the whole thickness and size of the three-dimensional hollow sandwich composites are not changed and the mass is not increased.
