Abstract

The invention discloses a graphene-glass fiber composite material and a preparation method thereof. Crosslinking of glass fibers can be realized by means of the swelling and fusing actions of grapheneoxide coatings on the surfaces of the glass fibers. Graphene oxide is taken as a sizing agent as well as a crosslinking agent with which the glass fibers can be coated uniformly, the crosslinking process is rapid and easy, and high crosslinking strength is achieved. Through further reduction, a graphene oxide crosslinking layer is turned into a graphene crosslinking layer, so that mutual action among the glass fibers is enhanced, contact resistance among the fibers is lowered, and the glass fibers show excellent mechanical performance, electric conductivity and heat conductivity and can be applied to a wild phase of the composite material. The method for crosslinking the glass fibers with the graphene has a great researching value and a wide application prospect.

Description

Technical field [0001] The invention belongs to the field of composite fibers, and particularly relates to a graphene-glass fiber composite material and a preparation method thereof. Background technique [0002] Glass fiber, also called glass inorganic fiber, can be divided into three categories: textile glass fiber, insulating glass fiber and glass fiber special products according to its technological perspective. Textile glass fibers are divided into filaments and short fibers, which are processed into intermediate products or final products. Glass fiber is made of silicate melt. The structure and composition of various glass fibers are basically the same, and they are all made of random SiO 2 The network is composed. The main component of glass fiber is SiO 2 . According to the shape and length, glass fiber can be divided into continuous fiber, fixed-length fiber and glass wool; according to the glass composition, it can be divided into no alkali, chemical resistance, high ...
