Problems solved by technology

In the ultra-high molecular weight polyethylene chest plate involved in this patent, the fiber sheets are arranged vertically and connected with each other by resin. When attacked by bullets and shrapnel, it is easy to cause insufficient connection of the fiber sheets, resulting in insufficient impact resistance. resulting in poor ballistic performance

Embodiment Construction

[0032] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0033] This example provides a method for preparing an ultra-high molecular weight polyethylene three-dimensional fabric, with a breaking strength of 32 cN / dtex, a breaking modulus of 1200 cN / dtex, an elongation at break of 2.78%, and a linear density of 3200D.

[0034] (2) Add 90 twists to the ultra-high molecular weight polyethylene fiber, and separate 80 small rolls, each small roll is 0.5kg;

[0035] (3) Arrange the small rolls on both sides of the wire frame in a 10×4 pattern; and wind them on the guide rollers through the wire mesh, layered frame, heald frame, and heald reed.

[0036] (4) Start the computer, turn on the weaving system, input the deep cross-link pattern, set the weft d...

Abstract

The invention provides a preparation method of an ultra-high molecular weight polyethylene three-dimensional fabric. The method comprises the steps of fiber preparation, fiber bundling, beaming, knitting, taking-down and edge finishing so as to weave the ultra-high molecular weight polyethylene three-dimensional fabric, wherein the ultra-high molecular weight polyethylene three-dimensional fabricis a prefabricated member, the good anti-elastic performance is achieved after a composite material is manufactured, when the ultra-high molecular weight polyethylene three-dimensional fabric is subjected to impact of external force, the good connection between fiber structure is achieved, the impact force is dispersed, penetration of bullets and shrapnel can be effectively avoided, and the fabrichas the good bulletproof performance for the human body or armored cars.

Description

technical field [0001] The invention relates to the field of three-dimensional fabrics, in particular to a preparation method of ultra-high molecular weight polyethylene three-dimensional fabrics. Background technique [0002] With the rapid development of modern science and technology, the attack weapon system has made great progress, forcing the metal protective layer of tank vehicles to become thicker and thicker, and its combat weight is increasing, which seriously affects the maneuverability and quick response ability of combat. It is increasingly difficult for traditional metal materials to meet the comprehensive combat technical index requirements of new tank vehicles. To reduce the weight of armored vehicles, improve the protective performance of tank vehicles, and enhance the ability to penetrate defenses on the battlefield, it is urgent to replace traditional metal materials with lightweight materials with high strength, good ballistic resistance and excellent fati...
