Abstract

The invention discloses an interlamination reinforced fiber composite material with a flow guiding layer . The interlamination improvement fiber composite material comprises an interlamination reinforced fiber pre-woven piece and basic body resin, the interlamination reinforced fiber pre-woven piece comprises glass felt laid layer by layer, flow guiding layer fiber cloth and interlamination continuous fibers, wherein the flow guiding layer fiber cloth is located at the position of a middle layer of the glass felt laid layer by layer, and the glass felt laid layer by layer and the flow guiding layer fiber cloth are sewn together through the interlamination continuous fibers. According to the interlamination reinforced fiber composite material, the interlamination shearing strength of the composite material can be improved while cost is reduced, and it can also be guaranteed that the fiber pre-woven piece can be uniformly soaked with resin.

Description

technical field [0001] The invention relates to the field of reinforcement materials, in particular to an interlayer reinforced fiber composite material and a manufacturing method thereof, more specifically, an interlayer reinforced fiber pre-woven piece suitable for a pultrusion molding process and a manufacturing method thereof. Background technique [0002] FRP reinforced with glass fiber has comprehensive advantages such as light weight, high strength, corrosion resistance, anti-seepage, heat insulation and sound absorption, and low temperature resistance. Exhibition hall, its application products are mainly roof panels, lighting strips, partition panels, wall panels, floors, industrial profiles, etc. The pultrusion molding process is a main molding process applied to building composite materials. The basic process is that the fiber reinforced material is pulled by an external force, dipped in glue, guided by a preformed template, and cured by a thermal mold to obtain a ...
