Description

technical field [0001] The invention belongs to the technical field of composite material genome, and relates to a rapid preparation method and device for a fiber-reinforced resin-based composite material laminate. Background technique [0002] Advanced polymer-based composite materials have a wide range of application requirements, but in the existing R&D model, each link of the R&D chain is mainly based on experience and trial-and-error screening, and lacks collaborative design optimization, resulting in high R&D costs, long experiment cycles, and large consumption of raw materials. . [0003] Therefore, the material genetic engineering proposed by referring to the ideas of the Human Genome Project is dedicated to solving this problem. Develop an advanced polymer matrix composite material research and development model based on material genetic engineering. Among them, it is one of the key links to explore new methods for the preparation, R&D and evaluation of high-throu...
