Problems solved by technology

Although this method solves the difficulty of fiber impregnation to a large extent, due to the introduction of polyethersulfone resin, it is still a carbon fiber reinforced polyethersulfone composite material to a large extent, and does not fundamentally solve the problem of polyether ether. The problem that ketone is difficult to impregnate, and the participation of solvent in the preparation process will cause certain harm to the environment
The invention of patent No. CN102134372A discloses a preparation method of a three-dimensional braided carbon fiber reinforced polyether ether ketone composite material, but this method simply mixes carbon fiber and polyetheretherketone fiber, and the impregnation effect is not obvious. Carbon fiber is also extremely susceptible to wear and tear. The three-dimensional weaving technology is more difficult and costly, and the resulting composite material cannot achieve high mechanical strength.

Abstract

The invention discloses a one-way continuous carbon fiber reinforced polyether-ether-ketone composite material and a preparation method thereof, belonging to the technical field of thermoplastic composite materials. The method comprises the following steps: (1) preparing polyether-ether-ketone multi-filaments with the line density of 10-150tex from special spinning grade polyether-ether-ketone materials by using a melt spinning method; (2) uniformly wrapping continuous carbon fibers with the prepared polyether-ether-ketone multi-filaments through a fancy twister, thereby preparing hybrid fiber bundles; (3) weaving the hybrid fiber bundles as warp fibers and the polyether-ether-ketone multi-filaments as weft fibers to form plain weave fabrics in a plain weaving mode; and (4) overlapping the woven plain weave fabrics, hot-pressing on a hot-pressing machine, exhausting, cooling, and demolding to obtain the one-way continuous carbon fiber reinforced polyether-ether-ketone composite material disclosed by the invention. The preparation method has the advantages that the whole process is free of a solvent, so that the environment is not polluted, the preparation process is relatively simple, and the prepared composite material is relatively high in strength.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic composite materials, and in particular relates to a unidirectional continuous carbon fiber reinforced polyether ether ketone composite material and a preparation method thereof. Background technique [0002] Continuous carbon fiber-reinforced resin-based composites usually use thermosetting resins as the matrix, because thermosetting resin prepolymers usually have low viscosity and easy handling at room temperature. These low-viscosity prepolymers can effectively infiltrate carbon fibers and Solidify and form during heating. In recent years, with the continuous improvement of the performance requirements of carbon fiber reinforced resin matrix composites, thermosetting resin matrix composites can no longer meet the requirements of high fracture toughness, high damage tolerance, etc., so thermoplastic resin matrix composites are receiving more and more attention. s concern. [0003] The rea...
