Abstract

The invention discloses a manufacturing method of a prepreg. The manufacturing method comprises the following steps that fiber cloth is paved and attached on release paper; liquid resin is provided onthe fiber cloth; and scraping and coating of the resin are achieved through a scraping plate, so that the resin is immersed into the fiber cloth to obtain the prepreg, wherein the scraping and coating step comprises the following sub steps that the scraping plate is used for performing scraping and coating at the position away from the fiber cloth by a first preset height, and then the scraping plate is lowered, so that the scraping plate is used for performing scraping and coating at the position away from the fiber cloth by a second preset height. According to the manufacturing method of the prepreg, the scraping plate is used for performing scraping and coating of the resin, so that the equipment investment of a production line is simplified, and the uniformity of the distribution of the resin on the fiber cloth is ensured by sequentially performing scraping and coating of the resin at different heights.

Description

technical field [0001] The invention relates to the field of composite materials, and more specifically relates to a method for making a prepreg. Background technique [0002] Prepreg refers to a semi-finished material formed by impregnating resin into fibers or fabrics under predetermined conditions and treating them. Most of the current composite materials are obtained by prepreg paving and treatment. Therefore, prepregs are Aerospace, rail transit, sports and leisure and other fields have a wide range of uses. [0003] At present, there are many methods for preparing prepregs, which can be roughly divided into two types: dry method and wet method. However, in the various existing preparation methods, if the quality requirements of the prepreg are high, for example, if the uniformity of the resin distribution is required to be high, there will be higher requirements for the entire set of equipment of the prepreg production line, and the production The cost of equipment, ...
