摘要
随着超高分子量聚乙烯(UHMWPE)纤维在轻质复合材料方面的应用越来越广泛,UHMWPE纤维作为增强基体制造符合材料的研究日益深入,但经过三维编织结构加工成的复合材料的应用性能研究尚在初期。本文以UHMWPE纤维做为轻质增强基体,采用三维编织的方法,经过真空模塑成型(VARTM)工艺制备复合材料。在相同的真空注塑成型工艺条件下,对比不同编织结构对复合材料的树脂体积分数、面密度、弯曲性能和抗拉伸性能的影响。通过对比深交联、浅交弯联、浅交直联编织结构VARTM制备的复合材料力学性能,结果表明:深交联结构复合材料的力学性能优于浅交弯联和浅交直联结构三维复合材料。
UHMEPE fiber is more and more widely applied in lightweight composites.The research of UHMWPE fiber as reinforcing matrix to manufacture composites is deepening,but the application performance of composites fabricated by3D weaving structure is still in the early stage.In this paper,the composites were prepared with three-dimensional weaving method by using UHMWPE fiber as the lightweight reinforcing matrix,and vacuum assistant resin transfer molding(VARTM).In the same VARTM process conditions,the effects of different weaving structures on resin volume fraction,surface density,bending properties and tensile properties were compared.The mechanical properties of the composites prepared by deep cross-linked,shallow cross-linked bending-connected,and shallow cross-linked straight-connected braided VETM were compared.The results showed that the mechanical property of deep cross-linked composite was better than that of shallow cross-linked bending-connected and shallow cross-linked straight-connected three-dimensional composites.
