The carbon fiber reinforced composite material has the advantages of high strength, small specific gravity, high temperature resistance, corrosion resistance and the like, and is widely used in various industries. The carbon fiber prefabricated body is used as a reinforcement body and plays a decisive role in the performance of the carbon fiber reinforced composite material. The needling-formed carbon fiber preform has the advantages of uniform pores, easy compact forming and the like, but because the needling needle has large damage to the fiber during needling, the bonding among the layers of the preform depends on the fiber implanted during needling, the implantation amount of the needling fiber is small, the length is short, and the bonding force among the layers of the preform is weak.
Accordingly, those skilled in the art have endeavored to develop a method for preparing a needle-punched carbon fiber preform, thereby overcoming the above-mentioned disadvantages of the prior art.

In order to achieve the aim, the invention provides a preparation method of a needle-punched carbon fiber preform, which comprises the following steps:
step 2, the needle plate drives the felting needles to move to be penetrated into the carbon fiber preform, and the felting needles simultaneously rotate for a first angle along a first direction until the felting needles reach the deepest position;
and 4, driving the felting needles to continuously move reversely by the needle plate and returning to the initial position.
Furthermore, a plurality of felting needles arranged in an array are arranged on the needle plate, and the plurality of felting needles rotate synchronously.
Furthermore, the number of the needle plates is two, and the two needle plates are respectively positioned on two sides of the carbon fiber prefabricated body.
Further, the two needle plates move synchronously towards the carbon fiber preform.
Further, the two needle plates move asynchronously facing the carbon fiber preform.
Further, the first direction in the step 2 and the second direction in the step 3 are opposite to each other.
Further, the first angle in the step 2 is 0 ° to 120 °.
Further, the second angle in the step 2 is-120 ° to 0 °.
Further, the first angle in the step 2 is 50 ° to 70 °.
Further, the second angle in the step 2 is-70 ° to-50 °.
The invention has the advantages that:
after needling, the fiber structures implanted in each needling hole are distributed in the prefabricated body in a three-dimensional spiral manner, so that the friction force between the implanted fibers and the prefabricated body is increased, the interlayer binding force is improved, and the felting needles can rotate to wind a plurality of strands of implanted fibers on the same felting needle together, so that the overall strength of the fibers is enhanced.
