Definitions
- the present invention relates to a ballistic vest and its manufacturing process, the vest being used for individual protection against penetration of firearm projectiles.
- Bulletproof vests consisting of a plurality of layers of high strength ballistic fabrics joined to other materials which are used as a support or to improve the penetration resistance of projectiles through the vest are known in the art.
- this type of vest is very heavy, and it is uncomfortable to wear it for long periods.
- prior art vests perform poorly on the NIJ STD 0101.06 (US Standard Minimum Ballistic Clothing Testing) drum test. In this test the vest is rotated by a drum, similar to a washing machine centrifuge, and at the end of the test the garment must be resistant without damage. As prior art vests have their unprotected layers, only joined by seams, when subjected to drum rotation, the fabric crumbles. This is because the seam allows a gap (GAP) between the fibers, which makes the product vulnerable and easy for the fibers to separate at these locations, so the fabric when subjected to Some effort goes away where there is no sewing.
- GAP gap
- the vest of the present invention has been developed, which unites in unprecedented ballistic protection and durability, even when subjected to said drum test.
- the present vest is formed of polyethylene resin coated aramid fiber fabric, where impregnation with this resin ensures uniformity to the fabric, increasing its ballistic capacity, absorbing the kinetic energy of a projectile, while giving it durability. Said vest does not suffer the usual damage to prior art vests when subjected to the drum test (NIJ STD 0101.06), it does not fray and its fibers do not bundle, as the resin holds the fibers together.
- the various layers of aramid fiber fabric that form the waistcoat are not fully sewn like the usual waistcoats, they have only a few connection points, which gives the vest more flexibility and comfort in use.
- Figure 1 illustrates a front view of the waistcoat of the present invention showing the joining points of the various layers of aramid fiber fabric.
- the present invention is directed to a ballistic vest (1) formed from a plurality of aramid-fiber fabric layers impregnated with resin. polyethylene on both sides of said fabric, which are then sewn to at least two points (2) distributed on the edge of the vest (1).
- the vest (1) is provided with a front and a rear portion which may be joined by any suitable means such as velcro, strap etc.
- the impregnation of said aramid fabric in general, consists of a bath of a polyethylene resin on both sides of said fabric.
- the material bath is preferably performed by flattening with a squeegee ruler in which the material is applied on both sides of the fabric, and thereafter applied temperature and cooling for curing.
- the fabric is cut to the shape of the vest (1), after which the various layers of cut fabric are joined by non-continuous stitching, the central portion of which is without joining points between the various layers, forming the vest ( 1).
- the present vest (1) is further characterized by the manner in which the various layers of aramid fiber fabric are sewn, the seam not being continuous, only a few stitches (2) being sewn which, in this particular example illustrated in Fig. 1, they are points (2) near vertices or places of change of direction of the tissue cut. ⁇
- the aramid fiber fabric used is made using high tenacity aramid fiber, preferably tenacity greater than 20 gpd (grams per denier).
- An example of suitable fabric has 18 ⁇ 0.5 inch weft and 18 ⁇ 0.5 inch warp, with 1500 denier title yarn.
- the fabric thus constituted offers good impact resistance of firearm projectiles, making it possible to use a reduced number of layers, providing a lightweight vest (1).
- a suitable polyethylene resin is particularly, but not limited to, a water-based polar polyethylene resin having a viscosity of 100 ⁇ 10 sec. Ford 06 cup, solids content 30 ⁇ 2% and density 0,98 ⁇ 0,03 g / cm 3 .
- the present invention further relates to a vest manufacturing process (1) which is carried out according to the following steps:
- the aramid fiber fabric is made of 18 ⁇ 0.5 inch weft and 18 ⁇ 0.5 inch warp, with 1500 denier title yarn and lxl construction, producing a fabric with tenacity greater than 20 gpd (grams). by denier).
- thermocouple calibration is about 200 to 760 ° C and thermometer at about 0 to 300 ° C.
- the fabric is cut to the desired waistcoat format, for example on a CNC (computer numerical control) machine. Following this step the layers of cut fabric are stitched together by joining them at some points distributed on the edge of the cutout; The set of sewn layers is then vinyl coated. The vest (1) is then identified with a tag.
- CNC computer numerical control
- the samples containing 24 layers of aramid fiber fabric, were fixed to a range at 5.0 m (16.4 ft) from the barrel of the test gun to produce a zero and thirty degree tilt impact.
- Speed gauges were positioned at 1.98 to 3.51 m (6.5 and 11.5 ft) where time interval counters (chronographs) were used to compute projectile speed at 2.44 m (8 .0 feet) from the barrel of the gun.
- Table 1 below provides a summary of the records.
- the present vest (1) has total penetration resistance of .44 Magnum and 9 mm projectiles by the combination of toughness of its technical fabric, impregnated with polymer resin.
