Problems solved by technology

However, due to the mechanical and physical and chemical properties of the reinforced fiber itself, the bulletproof helmet made of unit composite material also has many insurmountable problems.
For example, UHMWPE composite helmets have great high-temperature creep resistance, and are prone to poor deformation resistance in high-temperature environments. In addition, there is also a large amount of convex deformation in the process of resisting projectile penetration. It may indirectly cause impact injuries similar to blunt objects on the head; aramid composite helmets have a serious problem of anti-ultraviolet aging of the fibers themselves. During long-term use, the durability of the helmet is prone to be poor, and the overall rigidity of the helmet is also poor. The problem

Embodiment 1

[0034] A ballistic helmet lining part, reference figure 1 , the inner lining component includes: an inner lining shell 1 and a reinforcing guard 3, the inner lining shell 1 matches the shape of the helmet shell, so that the inner lining shell 1 can be close to the inner surface of the helmet shell The reinforcing guards 3 are arranged on the key protection parts 2 of the lining shell 1, and the key protection parts are: the forehead, the back of the head, the top of the head, and the left and right ears. The lining shell 1 is a hollowed-out structure, and the hollowed-out parts are as follows: figure 1 shown in 4.

[0035] The thickness of the inner lining part is 4mm, and it is made of carbon fiber impregnated with epoxy resin. The carbon fiber is T300, and it is designed with a plain weave fabric structure. The carbon fiber fabric is laminated and then impregnated with epoxy resin. After curing and molding, the resin content is 35% of the total mass of the inner lining par...

Embodiment 2

[0038] A bulletproof helmet inner lining part, the same as the first embodiment, the difference is: the thickness of the inner lining part is 5mm, and it is made of carbon fiber impregnated with phenolic resin. In the design of overlapping layers, the carbon fiber fabrics are laminated, impregnated with phenolic resin, and then thermally cured. The resin content is 45% of the total mass of the inner lining part.

[0039] The reinforcing protective member 3 is an alumina ceramic sheet with a thickness of 1 mm, a length and a width of 25 mm, and the alumina ceramic sheet is embedded in the above-mentioned key protection portion.

Embodiment 3

[0041] A bulletproof helmet inner lining part, the same as the first embodiment, the difference is: the thickness of the inner lining part is 4.5mm, and it is made of carbon fiber impregnated with unsaturated polyester resin, wherein the carbon fiber is T700, and the twill woven fabric is used The multi-layered design of the carbon fiber fabric is made by impregnating the carbon fiber fabric with unsaturated polyester resin and then thermally curing it. The resin content is 40% of the total mass of the inner lining part.

[0042] The reinforcing protective member 3 is an alumina ceramic sheet with a thickness of 1 mm, a length and a width of 30 mm, and the alumina ceramic sheet is embedded in the above-mentioned key protection portion.

Abstract

The invention relates to the technical field of bulletproof helmets, in particular to an inner lining component of a bulletproof helmet. The inner lining component includes: an inner lining shell and a reinforcement guard, the inner lining shell matches the shape of the helmet shell; the reinforcement guard is arranged at a key protection part of the inner lining shell; the inner lining shell matches the shape of the helmet shell; The lining part is made of carbon fiber impregnated with a thermosetting resin, and the carbon fiber is a two-dimensional fabric or a unidirectional fabric arranged in an orthogonal layup manner; The key protection part is buried, and the reinforcement protection part is attached to the key protection part; the reinforcement protection part includes: a solid sheet-shaped body or a porous sheet-shaped body. The invention adopts high-performance carbon fiber composite impact-resistant resin to form the inner lining part of the composite structure, and the key protection parts of the inner lining part are provided with reinforcing guard stickers, so as to realize the reinforcement of the anti-ballistic performance of the helmet, and at the same time increase the ability of the anti-bullet helmet to resist deformation .

Description

technical field [0001] The invention relates to the technical field of bulletproof helmets, in particular to an inner lining component of a bulletproof helmet. Background technique [0002] The disclosed information in this Background of the Invention is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] The composite material bulletproof helmet is an important equipment for individual head safety protection under the current situation of individual soldiers or single police dealing with dangerous events or military combat conditions. At present, lightweight high-performance fiber composite materials have become the main material of bulletproof helmets, and have completely replaced metal bulletproof helmets and become the mainstream of military and police un...
