Problems solved by technology

[0003] The purpose of the present invention is to propose a kind of ultra-high molecular weight polyethylene fiber and aramid fiber mixed cloth for the shortcomings of poor creep resistance and poor interface adhesion of traditional single ultra-high molecular weight polyethylene fiber cloth products. The structure improves the obvious problems of poor interface compatibility and creep resistance of UHMWPE fibers, and also solves the problem that due to the difference in diameter between UHMWPE fibers and aramid fibers, the material is prone to produce pores when there are too many layers, resulting in many pores in the composite material and resin filling. The problem of uneven glue quantity and decreased strength

Abstract

The invention relates to hybrid fabric by employing ultrahigh molecular weight polyethylene fiber and aramid fiber, wherein UHMWPE fiber has the advantages of small density, high specific strength, high specific modulus, good chemical corrosion-resistant and optical radiation-resistant performances, impact resistance, wear resistance, cutting resistance, low temperature deflection resistance, high electromagnetic transmissivity, and good biological compatibility. The UHMWPE fiber is polyethylene essentially, the melting point and the vicat softening point are low, so that the fiber heat resistance performance is poor, and creep deformation is obvious. The produced hybrid fabric improves the problems of interface compatibility and obvious creep deformation of the UHMWPE fiber, can be used for a resin-based composite material, solves the problems that diameters of the UHMWPE fiber and the aramid fiber are different, a gap is easily generated between the layers of the fiber cloth when the layers are overmuch, pore quantity of the composite material is large, glue amount of the resin after filling is inuniform, and intensity is decreased. The fiber can be used for enhanced fiber of the resin-based composite material.

Description

technical field [0001] The invention relates to a mixed fabric using ultra-high molecular weight polyethylene fiber and aramid fiber, especially the mixed fabric of ultra-high molecular weight polyethylene fiber and aramid fiber used in the field of various resin-based reinforced composite materials. Background technique [0002] Traditional ultra-high molecular weight polyethylene fiber cloth is usually woven from a single ultra-high molecular weight polyethylene fiber bundle, which is usually directly spun into fiber products such as body armor or gloves, and is not used in epoxy resin composite materials. Although it has been reported to modify the surface of UHMWPE fiber bundles to enhance its interfacial compatibility with the resin, it will also bring about problems such as a decrease in the tensile strength of the fiber bundle multifilaments; the Vicat softening point of UHMWPE fibers is 85 °C, It cannot be used at high temperature for a long time. The above two point...
