In-situ additive manufacturing equipment for continuous fiber reinforced high-performance resin composite material

Abstract

The invention discloses in-situ additive manufacturing equipment for a continuous fiber reinforced high-performance resin composite material. The in-situ additive manufacturing equipment for the continuous fiber reinforced high-performance resin composite material comprises a supporting frame, a printing head and a printing hot bed, wherein the supporting frame comprises an upper supporting plate and a lower supporting plate fixed to the upper supporting plate through three supporting stand columns; each supporting stand column is provided with a sliding block capable of sliding up and down along the corresponding supporting stand column; a supporting rod is hinged to each sliding block; the printing hot bed is fixed onto the lower supporting plate; the printing head comprises an upper connecting plate, a lower connecting plate connected with the upper connecting plate through a fixing column, four resin trays and one fiber tray which are arranged between the upper connecting plate and the lower connecting plate, a rotating mechanism fixed to the upper end face of the upper connecting plate, and a nozzle fixed to the lower end face of the lower connecting plate; the feeding end of the nozzle is provided with five feeding ports corresponding to the four resin trays and the one fiber tray respectively; and the rotating mechanism is hinged to one ends of the three supporting rods respectively. According to the in-situ additive manufacturing equipment for the continuous fiber reinforced high-performance resin composite material provided by the invention, in-situ impregnation and extrusion of multiple resin materials and continuous carbon fibers can be realized.

Description

technical field [0001] The invention belongs to the technical field of continuous carbon fiber reinforced resin, and in particular relates to in-situ additive manufacturing equipment for continuous fiber reinforced high-performance resin composite materials. Background technique [0002] Carbon fiber has the advantages of high specific strength, high specific modulus, high temperature resistance and good electrical conductivity. It has been widely used in aerospace, fan blades, high-speed rail fronts, car hoods and bicycle frames. Carbon fiber is generally used in the form of carbon fiber composite materials. At present, carbon fiber composite materials are mainly made of continuous carbon fiber reinforced resin, which has good strength and molding processability. [0003] At present, carbon fiber reinforced resin molding technology mainly focuses on continuous carbon fiber reinforced resin and short carbon fiber reinforced resin, among which continuous carbon fiber reinforc...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing continuous carbon fiber-reinforced resins all use a single resin and carbon fiber composite, so it is urgent to design a system that can impregnate multiple resins and carbon fibers at the same time
