Abstract

A skin-core structured glass fiber reinforced resin composite material is prepared by compounding continuous glass fibre wire beams, polypropylene resin and polyethylene resin, wherein the continuous glass fibre wire beams are uniformly dispersed and wrapped in the polypropylene resin; the polypropylene resin is coated with the polyethylene resin; and the continuous glass fibre wire beams are formed in a way that non-alkali untwisted glass fiber winding yarns are processed by a couplint agent. The fabricating method comprises the following steps: the non-alkali untwisted glass fiber winding yarns, which are processed by the couplint agent, pass through a cross extruder head to be coated by the molten polypropylene resin, are cooled and drawn to the next cross extruder head to be coated by the molten polyethylene resin, and then are cooled, drawn and wound to form reels. The composite material has the characteristics similar to those of thermoplastic engineering plastics, can replace metal, ABS (Acrylonitrile Butadiene Styrene), nylon and other engineering plastics, and can also serve as either a steel wire replacement product in a steel wire winding pipe or a reinforced body in a steel wire hose.

Description

technical field [0001] The invention relates to a composite material, in particular to a glass fiber reinforced resin composite material with a skin-core structure and a manufacturing method thereof. Background technique [0002] Polyethylene is one of the most important synthetic resins with the largest output and wide variety in the world. Due to the low heat resistance of polyethylene, low hardness, heat sensitivity, and easy creep, a single polyethylene material is often difficult to meet the requirements of special working conditions such as load and high speed, and often needs to be improved by blending and compounding. sex. Glass fiber reinforced plastics can greatly improve the mechanical properties, dimensional stability and other properties of the matrix resin. As a polymer reinforcement material, the effect is very significant, so it develops very rapidly and is currently the most widely used type of reinforcing fiber. [0003] The current research on glass fibe...
