Embodiment 1

[0044] Boron carbide particles with an average particle size of 200 μm and polyamide fibers are hot-rolled and cast, and the volume fraction ratio of inorganic particles / polymers is 58:42, and a stab-resistant composite sheet is attached to the multi-layer fabric to form a multi-layer fabric. The overall square meter weight is 5.26kg / m 2 , see Table 1 for details. The puncture probability of this composite fabric is zero. If converted into the current 6.66kg / m 2 The fabric has a puncture-resistant energy of 29.4J, which is equivalent to the current conventional square meter weight (6.66kg / m 2 ), it can reduce weight by about 21.0%. It adopts a homogeneous high-density stacked structure, which belongs to a homogeneous structure. It is a stab-proof mechanism that emphasizes both the collision barrier passivation mechanism and the reverse cutting roughening mechanism, which shows that its stab-proof performance has been improved. , and can be lightweight and softened.

Embodiment 2

[0046] Artificial diamond particles with an average particle size of 30 μm and polyimide fibers are mixed and hot-rolled, and the volume fraction ratio of inorganic particles to high polymers is 25:75. The anti-stab composite sheet is attached to the multi-layer fabric, and the resulting product is multi-layered. The overall square meter weight of the layer fabric is 5.14kg / m 2 , see Table 1 for details. The puncture probability of this composite fabric is zero. If converted into the current 6.66kg / m 2 The fabric has a puncture-resistant energy of 30.5J, which is equivalent to the current conventional square meter weight (6.66kg / m 2 ), it can reduce weight by about 22.8%. It adopts a gradient distribution stacking structure, which belongs to the gradient distribution of upper sparse and lower dense. It is the main mechanism of passivation of the collision barrier during penetration. softening and softening.

Abstract

The invention relates to a method for preparing a piercing-prevention clad sheet through waste fiber cut segment and inorganic particle mixing laying-up hot pressing and a purpose. The piercing-prevention clad sheet is formed in a manner that waste textile is subjected to slicing up, opening and smashing and then is cut into a fiber cut segment with the length of 1 to 10 mm, the fiber cut segmentand inorganic particles are mixed or the layer of fiber cut segment is laid, then, the inorganic particles are subjected to laying up, a mixed sheet layer or the laying-up sheet layer is subjected tohot melt pressure casting, and the thermoplastic piercing-prevention clad sheet with the uniform density and the gradient density is made. The piercing-prevention clad sheet adopts the piercing-prevention cutting-prevention mechanism with a collision blocking part as the main and a reverse cutting piercing sharp instrument as the auxiliary, the use face is the high-density flat rigid surface, andblocking passivating is achieved; the reverse face is the pliable and tough surface, the impact resistance and deforming energy consuming effects are high, and the method can be used for base materials of helmets, armors and the like of individual protective clothing of anti-terrorism, anti-riot, fire protection, anti-explosion, earthquake search and rescue and national defense military.

Description

technical field [0001] The invention relates to individual anti-stab and anti-ballistic clothing materials, belonging to the field of functional technical textiles, in particular to a flexible, light-weight, high-efficiency resin composite sheet for anti-stab, cut and chop clothing and its preparation technology. Background technique [0002] Specialized protective equipment is required for anti-terrorism, anti-riot, firefighting, mutation accidents and other rescue and escape in peacetime, as well as in war or armed operations. The basic requirements of these equipment are: high-efficiency protective function and the requirement of light weight and softness without barriers to movement; and the latter is becoming more and more important and becoming more and more lightweight and soft. The control of guns in our country is relatively strict. Although there are controls on knives, they are easier to obtain and carry with you. Therefore, clothing in anti-terrorism and riot co...
