Background
According to market feedback, more and more customers put higher requirements on the areal density of the bulletproof product, and the product is required to have certain comfort and stability. Especially for foreign customers, the demand for light weight is increasing. Taking aramid bulletproof materials as an example, the surface density of the domestic GA-3 bulletproof chip is 7.98kg/m2On the left and right, even the body armor resisting NIJ IIIA level can only be reduced to 5.88kg/m2On the other hand, there is a strong need for lightweight research on existing products.
According to the results of professional investigation, the ultra-light flexible body armor (PE) prepared by graphene adopted by a certain research institute of the middle-aged aviation industry has the surface density of only 5kg/m2On the left and right, it has attracted strong attention in an intra-industry academic conference. The graphene is known as the thinnest and hardest future material, and the development prospect is magical. With the increasing demand of domestic and foreign customers for high-grade body armor, graphene becomes one of the most popular materials in the application of the modified material of the bulletproof product. It has been reported that it can not only produce ultra tough body armor, but can even be developed to make ultra lightweight aircraft materials as thin as paper sheets. Therefore, the graphene modified bulletproof material meets the development trend and can meet the requirements of the market on high-grade bulletproof products.

The graphene modified bulletproof composite non-woven fabric is characterized in that the high-performance fiber is aramid fiber or high-strength high-modulus polyethylene fiber.
The bulletproof composite non-woven fabric modified by graphene is prepared by adopting bulletproof composite non-woven fabric prepared from graphene modified resin and high-performance fibers and preparing a bulletproof composite material by multilayer physical superposition or multilayer mould pressing, wherein the number of layers of the non-woven fabric is 20-80.
