Problems solved by technology

However, at high speeds, there is a dramatic increase in the molecular friction, resulting in an dilatant rheological response
[0003] Bulletproof materials known to date are high weight and bulk and lack flexibility, thereby greatly limiting their usefulness

Embodiment 1

[0018] Example 1: Preparation of bulletproof material.

[0019] Material X3M

[0020] Three layers of dense ballistic fibers based on ultra-high molecular weight polyethylene (UHMWPE) commercially available for example under the trademarks Dyneema or Spectra (hereafter referred to as mats or laminates), by having spherical SiO 2 Styrene-butadiene / polyterpene / dipentene based non-Newtonian shear thickening adhesives of nanoparticles and their clusters are linked (bonded, glued) together. The primary nanoparticles range in size from 1 nm to 20 nm, with clusters having sizes up to 500 nm. The adhesive forms a thin flat film with a maximum thickness of 0.5 mm. Three mats are thus bonded to form three layers.

[0021] A total of five triple layers were used to make the ballistic panel (on the ballistic side), which was further reinforced by ten additional individual mats. The final layer on the intercept side of the panel was a padding made of polyethylene (PE) foam that acted a...

Embodiment 2

[0047] Embodiment 2: ballistic limit speed

[0048] According to NIJ Standard-0101.04, the ballistic critical velocity for the individual materials prepared was determined. Using a 9x19FMJRN round weighing 8 grams (via S&B manufacturing) for testing. Velocity (thus complete or partial penetration under test conditions) is evaluated. The result is the arithmetic mean of the speed of 5 x (times) full penetration and 5 x (times) partial penetration.

Abstract

The present invention provides a material for ballistic protection, characterized in that it comprises: - a plurality of compact layers of ballistic fiber and - between the layers of ballistic fibers inserted at least one intermediate layer of non- Newtonian fluid exhibiting an increase in viscosity resulting from an increase in shear stress, optionally containing particles having the size of from 1 to 700 nm or antiplasticizing agents, said intermediate layer being placed either directly between layers of ballistic fiber, or placed between the layers on a packing or a perforated packing or applied on a fabric. The invention further provides a method of preparation of said material. This material is flexible and has a low weight and can be used in particular for bulletproof vests, combat helmets, personal body armor and / or for shielding light infantry and passenger automobiles.

Description

technical field [0001] The present invention relates to novel ballistic and puncture-resistant materials, their preparation and use. The material is particularly suitable for use in bulletproof vests, combat helmets, personal body armor and / or for protecting light infantry vehicles and passenger cars, trucks and movement control commands from ballistic threats. Background technique [0002] New improvements in the field of flexible ballistic resistant materials and material combinations are continually being attempted to keep in touch with the development of ballistic technology. US Patent No. 3,841,954 discloses laminated panels or laminates formed from layers of fabric stitched together and compressed under heat and pressure, thereby resulting in a rigid panel for use as a component in personal body armor. US Patent No. 3,509,833 discloses a flexible protective garment of ceramic plates mounted on an underlayment of flexible laminated fibers arranged obliquely in a cross-...
