Problems solved by technology

[0003] However, with the continuous development of military bulletproof materials to multi-functionality, high performance, and lightweight, the requirements for composite materials are getting higher and higher. However, due to the shortcomings of the adhesive itself, the comprehensive performance of this composite cloth is affected, and the body function is single. The UHMWPE fiber composite material made of it only plays the role of resisting bullet energy, and has no effect in anti-radar detection, which reduces the practicality of the battlefield

The method comprises the following steps that S1, a coupling agent is used to pretreat graphene so that the surface of the graphene can have active functional groups; S2, an absorbing agent is prepared; S3, graphene modified resinadhesive is prepared, wherein a graphene composite absorbing agent and a resin binder are combined and dispersed uniformly to obtain the graphene modified resin adhesive; S4, the graphene modified resin adhesive is put into a glue tank, and reinforcement ultra-high molecular weight polyethylene fiber (UHMWPE) is uniformly spread on a continuous line; S5, hot press molding is carried out on the prepared fiber composite material under a certain temperature, pressure and time conditions by a flat vulcanizing machine to prepare a sheet material. According to the preparation method of the graphenemodified bulletproof stealth composite material, the graphene is combined in the bulletproof material so as to obtain a stealth bulletproof structure integrated material, and the material has the advantages of radar stealth, bulletproof performance, lightweight and the like.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a graphene-modified bulletproof and stealth composite material. Background technique [0002] Ultra-high molecular weight polyethylene fiber (UHMWPE) bulletproof composite material is made by UHMWPE fiber impregnated with resin, arranged uniformly, parallelly and straightly under the condition of strictly controlling the glue content, and dried. The resin matrix generally includes polyethylene, polypropylene, vinyl copolymer, propylene copolymer, epoxy resin, phenolic resin, polyurethane, unsaturated polyester and so on. These low-modulus elastomers coat each fiber and, in addition to anchoring the fibers, can also improve the ballistic and impact resistance of the composite. [0003] However, with the continuous development of military bulletproof materials to multi-functionality, high performance, and lightweight, the requirements for composi...
