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

Abstract

An in-situ additive manufacturing equipment for continuous fiber-reinforced high-performance resin composite materials, including a support frame, a print head, and a printing heat bed; the support frame includes an upper support plate and a lower support plate fixed with the upper support plate through three support columns, Each support column is equipped with a slider that can slide up and down along the support column, and the support bar is hinged on the slider; the printing heat bed is fixed on the lower support plate; the print head includes: the upper connecting plate, and the upper connecting plate through the fixing column The connected lower connecting plate, four resin material trays and one fiber material tray arranged between the upper connecting plate and the lower connecting plate, a rotating mechanism fixed to the upper surface of the upper connecting plate, and a nozzle fixed to the lower end surface of the lower connecting plate; The feeding end of the nozzle is provided with five feeding openings respectively corresponding to four resin material trays and one fiber material tray; the rotating mechanism is respectively hinged with one end of three supporting rods. Utilizing the invention, the in-situ impregnation and extrusion of various 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
