Preparation method of carbon fiber plate and accordion based on carbon fiber plate

The invention discloses a preparation method of a carbon fiber plate and an accordion based on the carbon fiber plate. The preparation method of the carbon fiber plate comprises the following steps: S1, performing resin infiltration treatment on carbon fiber yarns and carbon fiber cloth to prepare carbon fiber prepreg yarns and carbon fiber prepreg cloth; s2, laying a plurality of layers of carbon fiber prepreg cloth according to different angles, and then laying at least one layer of carbon fiber prepreg yarn along four sides; s3, covering the structure in S2 with carbon fiber prepreg cloth; and S4, pressing the structure obtained in the S3 into the carbon fiber plate by adopting a flat plate pressing machine. The carbon fiber prepreg cloth and the carbon fiber prepreg yarn are laid and pressed according to a specific angle to form the carbon fiber plate, and then the carbon fiber plate is applied to the component of the accordion, so that the weight of the accordion can be greatly reduced, the carrying conv
