Problems solved by technology

[0002] In the traditional carbon fiber prototype product manufacturing technology, no matter sample preparation or mass production, it is necessary to design and manufacture corresponding molds to form products. Not only the time cost of mold manufacturing is high, but also the product development cycle is long and costly. The dimensional accuracy of carbon fiber prototype products is poorly controllable and poor in stability

Abstract

The invention discloses a preparation method of a carbon fiber hand plate. The preparation method comprises the following steps of that the carbon fiber block material or the high-temperature-resistant plastic block material is subjected to CNC machining to obtain a hand plate blank piece, and carrying out reinforcement treatment on the surface of the plate blank part by using a carbon fiber material. The carbon fiber block material or the high-temperature-resistant plastic block material is subjected to CNC machining to obtain the hand plate blank piece, then, the scaffold board blank is subjected to reinforcement treatment, so that a scaffold board product is obtained; on one hand, the preparation method does not need a corresponding mold for forming, the time cost of the mold cost and the time cost for designing the manufacturing mold are effectively saved, and the development period of the scaffold board product is shortened; on the other hand, so that the precision controllabilityand the stability of the obtained scaffold board product are high., and has relatively high tensile strength compared with a hand plate product prepared by the traditional mould, tensile modulus andshear strength and rigidity.
