树脂含量对碳布/环氧复合材料力学性能的影响

Effect of the Resin Content on the Mechanical Properties of Carbon Fabric/Epoxy Composites

主要研究了不同树脂含量下 ,碳布 /环氧复合材料的经向拉伸和纬向压缩性能 ,并初步探讨了树脂含量对复合材料拉伸、压缩性能的影响机理。试验结果表明 :树脂含量对复合材料力学性能的影响较大 ,当树脂质量含量在 4 2 %～ 4 5 %之间时 ,拉伸、压缩性能较好。

The tensile properties in warp direction and the compressive properties in weft direction of carbon fabric/epoxy composites with different content of epoxy resin were studied. The mechanism of the resin content affecting the tensile and the compressive properties of the composites was discussed. The results show that the resin content has a great effect on the mechanical properties of carbon fabric/epoxy composites. When the resin content is 42%～45%, both the tensile and the compressive properties of the composites are superior.
