Forming process and forming device of carbon fiber preform

Abstract

The invention relates to a forming process and a forming device of a carbon fiber preform, the forming device comprises a needling plate, the upper end face of the needling plate is vertically and downwards provided with a needling hole in a penetrating manner, a supporting plate is arranged above the needling plate, the upper end face of the supporting plate is provided with a driving mechanism, and the lower end face of the supporting plate is provided with a needling body corresponding to the needling hole; a cleaning plate is arranged between the needling plate and the supporting plate, a through hole is vertically and upwards formed in the upper end face of the cleaning plate, and the needling body penetrates through the through hole in a sliding mode. When the needling body penetrates into the needling hole, the cleaning plate is pressed on the upper end face of the composite layer to achieve a certain extrusion effect on the composite layer, so that the carbon fiber woven fabric and the carbon fiber net felt are better attached together, and when the supporting plate drives the needling body to rise quickly, and the rising speed of the cleaning plate is lower than that of the supporting plate, the cleaning plate can be used for cleaning the carbon fiber woven fabric and the carbon fiber net felt. The needling bodies are drawn out from the through holes in the cleaning plate, and then the fibers adsorbed on the surfaces of the needling bodies are removed.

Description

technical field [0001] The invention relates to a forming process and a forming device of a carbon fiber prefabricated body. Background technique [0002] During the processing of carbon fiber prefabricated body, the needle-punching process of the composite layer is a conventional method, and in the process of repeated piercing of carbon fiber by the needle-punched body, static electricity will be generated due to continuous friction, so that the broken fiber filaments will be adsorbed On the surface of the needled body, after a long period of accumulation, more filaments are wound on the needled body, which in turn will affect the normal acupuncture work, and the fibers wound on the needled body Cleaning up is more troublesome. [0003] In order to solve the above problems, the present invention proposes a carbon fiber preform forming process and forming device. Contents of the invention [0004] (1) Technical problems to be solved [0005] The purpose of the present i...

[0002] During the processing of carbon fiber prefabricated body, the needle punching process of the composite layer is a conventional method, but in the process of repeated piercing of carbon fiber by the needle punched body, due to the continuous friction There will be static electricity, so that the broken fibers will be adsorbed on the surface of the acupuncture body. After a long period of accumulation, more fibers will be wound on the acupuncture body, which will affect the normal acupuncture. Needling work is carried out, and it is troublesome to clean the fiber filaments wound on the needling body
