Description
Technical Field
The invention relates to a Kevlar fiber cloth reinforced polyurea composite material and a preparation method thereof.
Background
The polyurea elastomer as a high polymer material has lower density and price, and the excellent physical and chemical properties of the polyurea comprise extremely high tensile impact strength, flexibility, wear resistance, wet skid resistance, aging resistance, corrosion resistance and the like.
The American air force first applied polyurea coatings to the blast protection of buildings, and then the American Navy applied polyurea to the outer layer of high Motor multipurpose vehicle (HMMWV) armor plate in an attempt to mitigate ballistic debris and bullet hazards. Experimental research shows that the polyurea layer has a good protection effect and can remarkably enhance the penetration resistance of the armor plate to gunfire and explosive fragments. The polyurea elastomer can generate glass transition under high-speed impact, the strength modulus of the material can be greatly improved, and a large amount of energy is dissipated so as to achieve the aim of bulletproof property, and the elastic material is often used as a back plate to form a composite bulletproof structure of a steel plate/ceramic/elastic material (German leopard-2, Russian T90 tank).
Besides having good application prospect in the field of military bulletproof, polyurea is also widely applied in the field of large-scale infrastructure due to the waterproof, anticorrosion and wear-resistant properties. Such as pipeline corrosion prevention, tunnel waterproofing, bridge protection and the like.
The high-strength fiber mainly comprises carbon fiber, glass fiber, aramid fiber, ultra-high molecular weight polyethylene fiber and the like. These fibers are widely used in civil and military applications due to their ultra-high strength and modulus. Fiber reinforced polymer matrix composites are also widely used due to their excellent properties.
The fiber reinforced composite material has superior performance to pure fiber and matrix. Firstly, the matrix can keep the position and direction of the fiber pairs unchanged during impact and can disperse the stress between the fibers; secondly, the existence of the matrix can protect the fiber, and avoid the reduction of the fiber performance caused by environmental factors, such as the reduction of the impact resistance of the pure fiber under the high humidity condition and the reduction of the mechanical property caused by the ultraviolet radiation photodegradation; delamination caused by matrix cracking is also an energy absorption mechanism. The impregnated aramid fiber fabric has better dynamic anti-intrusion performance. When used as lightweight ballistic or soft armor, the lower adhesion of the fibers to the matrix allows for greater deformation of the fibers, which in turn allows for greater absorption of impact energy.
The fiber cloth reinforced polyurea-based composite material laminated plate integrates the common advantages of fibers and polyurea elastomers, and the fiber cloth reinforced polyurea-based composite material laminated plate with high strength, high toughness, low density, corrosion resistance, water resistance and particularly elastomer invasion cutting resistance can be obtained through different layers and fiber volume fraction design. The method can be used in the field of large-scale infrastructure, such as pipeline corrosion prevention, tunnel water prevention, bridge protection, house explosion prevention and the like; can be used in the civil protection field, such as helmets, kneepads and other protective equipment; and the composite material can also be used in the military field, such as body armor, armor plate, airplane structure and the like.

secondly, mixing the reaction liquid A and the reaction liquid B, and stirring for 2-10 min to obtain a polyurea elastomer; the molar ratio of diamine in the reaction liquid A to diisocyanate in the reaction liquid B is 1 (0.8-1.2);
thirdly, soaking Kevlar fiber cloth into the polyurea elastomer, and vacuumizing for 2-10 min to obtain the Kevlar fiber cloth soaked with polyurea;
and fourthly, paving the Kevlar fiber cloth soaked with the polyurea in a mold layer by layer, applying pressure to the Kevlar fiber cloth soaked with the polyurea on the uppermost layer by using a press machine under normal pressure or vacuum atmosphere, keeping the pressure for 0.1-2 hours under the pressure of 10-100 kN when the pressure is increased to 10-100 kN, and demolding after the polyurea is solidified to obtain the Kevlar fiber cloth reinforced polyurea-based composite material.
