Problems solved by technology

Since high temperature resistant thermoplastic resins generally have good solvent resistance and oil resistance, and are insoluble in conventional organic solvents, hot melt impregnation is mainly used at present, but due to the relatively high melt viscosity of thermoplastic resin matrix
Hot-melt prepreg has high requirements on equipment, and it is difficult to control technology and process, so its application is greatly limited

Embodiment 1

[0023] The plain weave 2D carbon fiber woven preform with a weaving angle θ = 90° is soaked in acetone and heated for 48 to 72 hours with ultrasound to remove the carbon fiber surface sizing agent, then washed with dedistilled water, dried, and weighed. Dissolve the biphenyl polyether ether sulfone (PPSU) powder in an appropriate amount of chloroform to form a polymer solution with a mass concentration of 3.2%, and then in the solution according to the mass ratio of carbon fiber (CF): polyether ether ketone ultrafine powder (PEEK) = 0.45:0.55 ratio of high melt index polyetheretherketone (PEEK) superfine powder is added, fully stirred, so that it is evenly mixed to obtain a suspension. Spread the treated carbon fiber fabric in a cloth funnel, pour the prepared suspension on the carbon fiber fabric, filter under low pressure, and take it out after the chloroform is completely volatilized. Put it in a hot press, raise the temperature to 380°C, melt for 60 minutes, pressurize at ...

Abstract

The invention discloses a preparation method for a carbon fibre fabric-reinforced polyetheretherketone polymer composite material, and belongs to the technical field of composite material preparation. The preparation method comprises the following steps: carrying out slurry remover treatment on the surface of a carbon fibre fabric; dissolving polyarylsulfone powder in chloroform or N,N-dimethyl formamide to prepare polymer solution with a certain concentration, then adding polyetheretherketone ultrafine powder, and stirring to obtain a suspension; flatly paving the treated carbon fibre fabric in a cloth-type funnel, pouring the suspension on the carbon fibre fabric, and carrying out low-pressure suction filtration; melting, pressurizing and maintaining a pressure in a hot press; then cooling to a room temperature and demoulding. The preparation method disclosed by the invention solves the problems of high process control difficulty, too high equipment and energy consumption costs, poor adhesive property of polyetheretherketone and carbon fibres, and the like of the existing polyetheretherketone resin during a carbon fibre soaking process, so that preparation for the large fibre fabric-reinforced polyetheretherketone composite material is realized by using simple equipment and a simple and convenient process method.

Description

technical field [0001] The invention belongs to the technical field of preparation of fiber fabric resin-based composite materials, and in particular relates to a preparation method of carbon fiber fabric reinforced polyether ether ketone composite materials. Background technique [0002] Fiber fabric reinforced high-performance thermoplastic resin-based composites are used in almost all advanced engineering structures such as aircraft, helicopters, space shuttles, ships, ships, ocean platforms, automobiles, sports equipment, bridges, buildings, etc. The use of fiber fabric reinforced high-performance thermoplastic resin composites is growing, not only in traditional industrial fields, but also in some emerging fields (such as biomedicine). However, there are not many domestic research reports on this aspect. [0003] The prominent features of carbon fiber are high strength, high modulus, low density, and its specific strength and specific modulus are much higher than alloy...
