specific Embodiment approach 1

[0025] Specific embodiment 1: The carbon fiber used in this embodiment is the T300 carbon fiber provided by Harbin FRP Research Institute; the polyether ether ketone filament is purchased from Changzhou Chuangying New Material Technology Co., Ltd., the model is 200D36F; a small hand-knitting machine is used to carry out Plain weave.

[0026] In this embodiment, the preparation method of carbon fiber reinforced polyetheretherketone composite material is specifically carried out according to the following steps:

[0027] Step 1. Use plain weave to weave carbon fiber and PEEK fiber and then cut them. The warp yarn is carbon fiber, the weft yarn is PEEK fiber, and the number of PEEK fiber strands is 6 strands, 12 strands or 18 strands respectively. Strand, obtains mixed weaving flexible premix;

[0028] Step 2. Lay the mixed-knitted flexible premix obtained in step 1. A total of 8 layers are laid, wherein the unidirectional carbon fibers of any adjacent two layers are set at an a...

Abstract

The invention relates to a carbon fiber reinforced polyetheretherketone composite material and a preparation method thereof, belongs to the technical field of continuous carbon fiber reinforced polyetheretherketone composite materials and aims to solve the technical problem of difficulty in laminated paving existing in the preparation of a complex component when an existing APC-2 prepreg is applied. The carbon fiber reinforced polyetheretherketone composite material is prepared by weaving carbon fibers and polyetheretherketone fibers in a mixed manner by using two-dimensional weaving and sequentially performing shearing, laminated paving and hot-press molding treatment, wherein warp yarns are the carbon fibers; weft yarns are the polyetheretherketone fibers; arbitrary two layers of unidirectional carbon fibers in the laminated paving process are in included angle arrangement. According to the preparation method provided by the invention, the flexibility and the hangability of the fibers are kept, and the laminated paving is more convenient.

Description

technical field [0001] The invention belongs to the technical field of continuous carbon fiber reinforced composite materials; specifically carbon fiber reinforced polyether ether ketone composite materials and a preparation method thereof. Background technique [0002] Continuous carbon fiber reinforced polyether ether ketone composites have excellent performance and are widely used in a wide range of fields. In the 1980s, the British ICI company first prepared unidirectional carbon fiber reinforced polyetheretherketone prepregs by means of pultrusion melt impregnation, and successively developed a series of prepregs named APC (abbreviation for aromatic polymer composites). Among them, APC-2 is the most widely used continuous carbon fiber reinforced polyetheretherketone composite material prepreg. This prepreg itself is already a composite material with certain mechanical strength. There are many problems in the preparation of complex components. Big limitations. [0003]...
