Abstract

The invention discloses a molding method for a graphene modified epoxy resin high-strength fiber wound shell. The molding method for the graphene modified epoxy resin high-strength fiber wound shell comprises the following steps that firstly, oxidized graphene is modified; secondly, modified graphene-enhanced epoxy resin is adopted; thirdly, components and parts of the wound shell are molded; fourthly, graphene modified epoxy resin is adopted, and the composite material shell is molded through wet wrapping of graphene modified epoxy resin; fifthly, the shell is solidified; and sixthly, the shell is demolded, and high-strength graphene modified epoxy resin fiber wound shell is acquired. According to the molding method for the graphene modified epoxy resin high-strength fiber wound shell, graphene is modified so that graphene is fully fused with epoxy resin, then the fiber wound shell is molded through wet wrapping of graphene modified epoxy resin; and the special structural property ofgraphene is utilized to fully strengthen the fiber wound composite material.

Description

technical field

[0001] The invention relates to the technical field of rocket motor casing molding, in particular to a molding method for a graphene-modified epoxy resin fiber-wound casing.

[0002] technical background

[0003] Under the same volume and weight, improving the blasting strength of the filament-wound engine casing is one of the goals that the design and manufacture of the engine casing has been pursuing. Graphene is a two-dimensional honeycomb planar structure formed by a single layer of carbon atoms tightly packed, with a thickness of only 0.34nm. It is currently the thinnest and most ideal two-dimensional nanomaterial. The special structure endows it with excellent electrical, optical, force, thermal and other characteristics;

[0004] The existing rocket casings are all wound with ordinary epoxy resin fibers, so there is a lot of room for improvement in their weight and blast strength. Contents of the invention
