Problems solved by technology

However, bulletproof helmets made of a single composite material also have many problems due to the physical properties of the fiber itself. For example, the high-temperature creep of UHMWPE fiber composites is serious, and the overall deformation of the projectile penetration protection process is relatively large; The problem of anti-ultraviolet aging is serious, which affects the service life and safety of the overall helmet

Embodiment 1

[0032] A kind of composite rigidity reinforced bulletproof helmet (reference figure 1 ), which includes: a bulletproof helmet shell 1, a composite rigid reinforced inner liner 2, a suspension system 3 and a reinforcing rib 4, and the composite rigid reinforced inner liner 2 is fixed on the inner surface of the bulletproof helmet shell; the suspension system 3 is fixed on the edge of the composite rigid reinforced inner liner 2; the bulletproof helmet shell 1 is formed by compounding fiber and thermoplastic resin; the composite rigid reinforced inner liner 2 is formed by compounding carbon fiber and thermosetting resin matrix, and the composite The rigid reinforced inner lining layer 2 has a hollow mesh structure; the reinforcing ribs 4 are fixed on the surface of the composite rigid reinforced inner lining layer 2 through bolts 5 .

[0033]The bulletproof helmet shell 1 is laminated by the unidirectional prepreg fabric of UHMWPE fiber impregnated with polyurethane, and the lam...

Embodiment 2

[0036] A composite rigid reinforced bulletproof helmet, and the structure and connection relationship are the same as embodiment 1, the difference is:

[0037] (1) The bulletproof helmet shell 1 is laminated by an orthogonal prepreg fabric impregnated with aramid fiber polyolefin resin, and the laminated prepreg fabric is pressed at 130 ° C and 20 MPa for 30 minutes. Forming a bulletproof helmet shell 1 with a thickness of 6 mm.

[0038] (2) The composite rigid reinforced inner lining layer 2 is made of a composite material formed by unidirectional fabric cross-laminated T1000 carbon fiber impregnated with phenolic resin, and its thickness is 5 mm. The composite rigid reinforced inner lining layer 2 is vacuum-assisted. It is embedded in the inner surface of the bulletproof helmet shell, and the composite rigid reinforced inner liner 2 and the bulletproof helmet shell 1 are formed as a whole by means of bonding.

Embodiment 3

[0040] A composite rigid reinforced bulletproof helmet, and the structure and connection relationship are the same as embodiment 1, the difference is:

[0041] (1) The bulletproof helmet shell 1 is laminated by unidirectional prepreg fabric impregnated with PBO fiber polyethylene resin emulsion, and the laminated prepreg fabric is pressed at 140 ° C and 21 MPa for 35 minutes. Forming a bulletproof helmet shell 1 with a thickness of 5.5mm.

[0042] (2) The composite rigid reinforced inner liner 2 is made of a composite material formed of two-dimensionally woven cross-laminated T700 carbon fibers impregnated with unsaturated polyester resin, and its thickness is 4 mm.

Abstract

The invention belongs to the technical field of bulletproof helmets, and particularly relates to a bulletproof helmet with a composite rigid reinforced lining layer implanted. The bulletproof helmet comprises a bulletproof helmet shell, the composite rigid reinforced lining layer and a hanging system; the composite rigid reinforced lining layer is fixed to the inner surface of the bulletproof helmet shell, the hanging system is fixed to the edge of the composite rigid reinforced lining layer, the bulletproof helmet shell is formed through compositing of fibers and thermoplastic base resin, thecomposite rigid reinforcing lining layer is formed through compositing of carbon fibers and a thermosetting resin base, and the composite rigid reinforced lining layer is of a hollow mesh structure.The fiber composite resin is used for preparing the helmet, the composite rigid reinforcing lining layer is arranged to be of the hollow mesh structure, the uniform and stable rigid supporting is provided for the inner surface of the bulletproof helmet shell, stable rigidity after bullets impact the helmet shell is ensured, and the phenomenon that large back protruding deforming is generated in the helmet shell, and the head of the human body is hurt in an impact manner is avoided.

Description

technical field [0001] The invention belongs to the technical field of bulletproof helmets, in particular to a bulletproof helmet implanted with a composite rigid reinforced inner liner. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Bulletproof helmet is a kind of protective equipment for individual combat, which has the most direct protective effect on the penetration damage of projectiles on the head of individual soldiers. At present, bulletproof helmets made of traditional lightweight composite materials are prepared by molding with UHMWPE composite materials or aramid composite materials. Bulletproof helmets made of composite materials are light in we...
