Abstract

A polymer matrix composite used for liquid-oxygen containers and a preparation method and a using method of the polymer matrix composite relate to polymer matrix composite and a preparation method thereof. Aiming to solve the problems that existing liquid-oxygen containers made of resin matrix composite are poor in liquid oxygen compatibility or liquid-oxygen containers made of perfluor polymer are difficult in forming. The polymer matrix composite used for the liquid-oxygen containers is made of epoxy resin, benzoxazine resin, prussic acid fat, solvent and auxiliaries. The preparation method includes: firstly, weighing; secondly, preparing prussic acid fat prepolymer; thirdly, fusing and mixing to obtain epoxy / benzoxazine rubber solution; and fourthly, preparing the rubber solution. The using method includes: firstly, subjecting to impregnation, forming by combining a winding forming method, a vacuum bag hot-pressing tank forming method and a hang-pasting forming method, curing by a gradient-heating curing method, and finally performing thermal treatment, and obtaining a liquid-oxygen container. The polymer matrix composite is mainly used for preparing liquid-oxygen containers.

Description

technical field [0001] The invention relates to a polymer-based composite material and a preparation method thereof. Background technique [0002] The basic technology of composite cryogenic liquid oxygen container originated from the late 1980s to the early 1990s, and was first developed by the United States for the development of high-performance spacecraft. [0003] Compared with the traditional all-metal material liquid oxygen container, the polymer matrix composite material cryogenic liquid oxygen container has many advantages such as light weight, high pressure bearing, and safe failure mode of leakage before bursting. These advantages of composite material low-temperature liquid oxygen container will make it widely used in various industrial sectors in the future: clean energy vehicles powered by hydrogen-oxygen fuel cells have become the development trend of clean energy transportation in the future; steelmaking requires a large amount of oxygen; mobile Industries s...
