Embodiment 1

[0025] Prepare 1000 mL of a DMF solution of polyetheretheramine with a mass percent concentration of 5%, place it in a fiber treatment solution tank, and keep the solution temperature at 40°C. The carbon fiber filament (T700) is pulled by the pulling roller at a line speed of 1m / min, and then immersed in the above polyetheretheramine DMF solution for coating; after heating and drying system, the drying temperature is 150°C, and the surface coating is obtained after winding. Continuous carbon fiber filament (L-CF-5) coated with polyetheretheramine. The amount of sizing on the fiber is calculated as 1.9% by mass weighing method.

Embodiment 2

[0027] The method described in Example 1 was changed to 1% by mass of the polymer solution to obtain a continuous carbon fiber (L-CF-0.1) coated with polyetheretheramine. Calculate fiber sizing amount 0.5wt% by mass weighing method.

Embodiment 3

[0029] The method described in Example 1 was changed to 20% by mass of the polymer solution to obtain a continuous carbon fiber (L-CF-20) coated with polyetheretheramine. The amount of fiber sizing was calculated to be 5.2wt% by mass weighing method.

Abstract

The invention provides a continuous fiber-reinforced polyaryletherketone composite material and a preparation method thereof, and belongs to the technical field of polymer composite materials and preparation thereof. The preparation method of the continuous fiber-reinforced polyaryletherketone composite material comprises the steps that the characteristics of solubility of polyarylether amine resin is adopted, firstly surface finish is carried out on a fiber, then polyarylether amine is hydrolyzed, and the continuous fiber with a crystal type polyaryletherketone interface bonding agent is prepared; and then a polyaryletherketone thin-film material is used, a composite winding technology and a layer-by-layer laying technology are adopted to prepare a continuous fiber-reinforced polyaryletherketone composite material precursor, and then the polyaryletherketone continuous fiber composite material is obtained through hot pressing. According to the continuous fiber-reinforced polyaryletherketone composite material and the preparation method thereof, a bonding interface of the fiber and the resin is improved, very high mechanical strength is achieved, and meanwhile, a novel technology for preparing the fiber-reinforced polyaryletherketone composite material is developed. The composite material has wide application prospects in the fields such as aviation, spaceflight and industrial machinery manufacturing.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials and preparation thereof, and in particular relates to a continuous fiber reinforced polyaryletherketone composite material and a preparation method thereof. Background technique [0002] In recent years, aromatic polyaryletherketones have been widely used as high-performance engineering thermoplastics. This type of polymer has excellent mechanical properties, electrical insulation properties, corrosion resistance and high temperature resistance. Polyaryletherketone composite materials inherit the excellent performance of polyaryletherketone resin, and at the same time have the potential of light weight and high strength, and the potential of replacing steel with plastic has been extensively studied. Continuous fiber reinforced PEEK materials are usually prepared by melt prepreg, solution prepreg and fiber blending techniques. The preparation process of this type of composite ...
