以不饱和树脂和环氧树脂为基体,与三维中空织物分别复合成中空夹芯织物复合材料,利用万能材料试验机分别对2种复合材料的拉伸、压缩和弯曲性能进行测试,研究了树脂种类对复合材料力学性能的影响规律。结果表明:不饱和树脂与固化剂质量比为100∶2,固化温度为70℃时,复合材料具有最佳的拉伸、弯曲和压缩性能。环氧树脂基复合材料的弯曲和压缩性能远优于不饱和树脂基复合材料,而拉伸性能则相差不大。
Unsaturated resin and epoxy resin were used as matrix to be combined with 3D hollow sandwich fabric into 3D hollow sandwich fabric composite materials respectively.The universal testing machine was used to test the tensile,bending and compressive properties of above composites.The influence of resin type on the mechanical properties of 3D composites was studied.The results showed that the unsaturated resin based 3D composites had the best tensile,bending and compressive properties when the ratio of unsaturated resin to curing agent was 100∶2 and the oven temperature was 70℃.The bending and compressive properties of composites were much larger than those of unsaturated resin-based composites,but the tensile properties were not big between these two.
