摘要
将石墨烯和二硫化钼(MOS2)的复合粉体加人到E-44环氧树脂中并以650低分子质量聚酰胺固化,制备了复合材料。通过力学性能、耐磨性测试研究了复合粉体中石墨烯含量及复合粉体用量对材料性能的的影响。结果表明,粉体中石墨烯质量分数为20%时材料的弯曲强度达到最大值35.73MPa,较只掺加MOS2的体系提高了77%,而复合材料的固液比不宜超过1:20。石墨烯/MOS2复合粉体对环氧复合材料的力学强度、断裂韧性以及耐磨性能均有明显的改善作用。
The compound powder of graphene and molybdenum disulfide(MoS2)was added to E-44 epoxy resin and cured with 650 low molecular weight polyamide to prepare a composite.The effects of the graphene content and the amount of compound powder on the properties of the composite were studied by testing the mechanical properties and abrasion resistance.The results showed that the flexural strength of the material reached a maximum of 35.73 MPa when the graphene mass fraction was 20%,which was 77% higher than that of the system containing only MoS2,and the solid-liquid ratio of the composite material should not exceed 1:20.The graphene/MoS2 compound powders had obvious effects on improving the mechanical strength,fracture toughness and wear resistance of the epoxy composites.
