Composite resin material capable of resisting high and low temperatures and high-energy radiation environment, and preparation method thereof

Abstract

The invention discloses a composite resin material capable of resisting high and low temperatures and a high-energy radiation environment, and a preparation method of the composite resin material, belonging to the field of an organic resin and chemical fiber composite material and preparation thereof. The composite resin material comprises a base layer and a composite layer closely combined with the base layer, wherein the base layer is a fabric taking heterocyclic aromatic polyamide fibers as a main material; and the composite layer is made of m-xylylenediamine tetra-glycidyl-amine epoxy resin and / or reinforced resin taking m-xylylenediamine tetra-glycidyl-amine epoxy resin as a matrix material. The preparation method sequentially comprises the following steps of: gluing in a two-step method, cold press molding, hot press curing, carrying out heat preservation at a constant temperature, and cooling to obtain the finished product. The resin-based fiber composite material disclosed by the invention is capable of resisting high and low temperatures and high-energy radiation.

Description

technical field [0001] The invention belongs to the fields of organic resins, chemical fiber composite materials and their preparation, and particularly relates to resin composite materials for extreme applications (high and low temperature resistance and high-energy radiation environments) and their preparation. Background technique [0002] Due to the characteristics of insulation, heat insulation, and no magnetic interference, multifunctional epoxy resin has become an indispensable and important material in ultra-low temperature equipment. However, currently commonly used bisphenol A epoxy resins and phenolic glycidyl ether resins do not have the above-mentioned comprehensive properties; with the continuous expansion of the field of use of composite materials in ultra-low temperature environments, the above-mentioned needs and deficiencies have become more prominent; Epoxy resins were modified to accommodate this need.

Problems solved by technology

However, currently commonly used bisphenol A epoxy resins and phenolic glycidyl ether resins do not have the above-mentioned comprehensive properties; with the continuous expansion of the field of use of composite materials in ultra-low temperature environments, the above-mentioned needs and deficiencies have become more prominent; Epoxy resins are modified to accommodate this need

However, the low-temperature resistance of ordinary epoxy resins mainly depends on the addition of low-viscosity tougheners; for example, the most commonly used bisphenol-A epoxy resin material has poor condensation resistance to low-temperature and high-energy radiation. Although composite materials made of fiber and carbon fiber as reinforcement materials alleviate the above-mentioned defects to a certain extent, the result leads to poor comprehensive performance (such as electrical performance)

To sum up: At present, there is a lack of a resin-based fiber composite material that is resistant to high and low temperature and high-energy radiation in the field of materials.
