Definitions

  • the present invention generally relates to projectile resistant matrix and, more particularly to manufacture of projectile resistant armor trauma shields.
  • Conventional ballistic resistant armor utility trauma plates include metal and ceramic based armor used for both military and civilian use. While metal based armor is effective in stopping most types of rounds, it suffers the disadvantage of being very heavy and this property leads to performance degradation, especially in use with personal body armor. While ceramic based armor trauma plates are somewhat effective in stopping various rounds, it has the disadvantages of being brittle and subject to cracking and is much less effective on stopping multiple rounds than the metal based armor trauma plates. In addition, there are currently no effective side or other specific area utility trauma plates either incorporated into the vests or that can be easily attached to a vest or placed in pocket of coats, jackets, vests uniforms or the like in order to effectively protect the vulnerable side area or other specific areas or body parts required of the personnel.

After completion of the spray onto the plates, one or more layers of projectile resistant textile 302 or 310 are placed on top of the plates.
  • FIG. 13B is also an exemplary illustration of a manufacturing technique for the spray-on application of the encapsulation component (a third type of elastomer) onto the projectile resistant matrix. As illustrated, it is best to spray the second and the third types of polymer resins within a booth or closed area 1340 that also includes an exhaust system 1342 for safety. As illustrated in the FIG. 13B, the encapsulating (third type of) elastormer 1360 is directly sprayed onto the surface area of the projectile resistant matrix 1302 using the spray-mixing gun 1312.
  • the encapsulating (third type of) elastormer 1360 is directly sprayed onto the surface area of the projectile resistant matrix 1302 using the spray-mixing gun 1312.
  • the third type of polymer resin (a third type of Polyurea) that forms the encapsulation covering 1360 may comprise equal parts of an isocyanate and amine- terminated resin, which when combined comprises the third type of Polyurea.
  • the third type of polymer resin (the third type of elastomer) is sprayed-on in the form of a third type of fluid precursor that crosslink's (cures) under ambient conditions to form a solid rubbery layer that adheres strongly to the projectile resistant matrix 1302, forming into Polyurea.
  • the selected third type of elastomer is preferably one that cures without addition of heat and without evolving solvent vapors, so that it can be applied in an inhabited room 1340.
  • elastomers that cure within these limitations are two-component systems "A” and "B,” that is, cross linking results from reaction between two different chemical components, the "A,” which is the isocyanate and the "B,” which is the amine-terminated resin. Both components may end up as part of the elastomer, or one component may act as a catalyst to enable the other component to react within itself to form crosslink's, which solidify the fluid into a solid.
  • One preferred third type elastomer is a third type of Polyurea, preferably sprayed on as a two-part mix.
  • the spray-mixing gun 1312 mixes the two components 1304 and 1306 often called Part A and Part B, in the correct stoichiometric ratio so that Part A 1304 and Part B 1306 mix in flight and begin to cure into a rubbery solid immediately.
  • the third type of mixed precursor is fluid for a short time, then becomes a gel as crosslink's start to form.
  • a gel does not run or slump, but is plastically deformed by small forces.
  • third type of Polyurea is cured and considered a solid, although it is rubbery.
  • a preferred, non-limiting exemplary formulation of the third type of elastomer that encapsulates the projectile resistant matrix 1302 using the spray-on application technique has been found to have the following typical, exemplary properties / characteristics:
  • the equipment used After preparing the composite (the part A and part B) for the spray of the encapsulating layer of third type of Polyurea, the equipment used must be set to specified temperature ranges, depending on material in use, the weather conditions, and etc.
  • the hoses 1350 are pre-heated for approximately 20 to 30 minutes before the main heat exchangers for the "A & B" material is activated, and the part "B" side of the composite is pre-mixed for approximately 30 minutes, at minimum.
  • the pressure setting, gauges "A & B" are 1800 to 2500 Pounds per Square Inch (psi), and must be within 500 psi of each other.
  • the final encapsulating layer 1360 of the third type of Polyurea is sprayed from the application zone 1320 facing in the direction of the exhaust 1342 and in front and center of the projectile resistant matrix 1302.
  • the spray-mixing gun 1312 is aimed at zone 1 , 1316 bottom-left corner away from the user.
  • the spray towards the projectile resistant matrix 1302 is in sweeping passes in an up to down motion overlapping each pass and working towards zone 2, 1318, finishing the spray of the third type of elastomer at zone 2, 1318.
  • the gun is then aimed at zone 1, 1316 top left corner, but the spraying action is in a lateral (side-to-side) motion from zone 1, 1316 to zone 2, 1318, from top to bottom.
  • the spraying is repeated (up and down and laterally) while the projectile resistant matrix is rotated on a base unit 1358 until a desired thickness for the encapsulation reached.
  • the projectile resistant matrix can be facing the sprayer horizontally or vertically.
  • the labels such as left, right, front, back, top, bottom, forward, reverse, clockwise, counter clockwise, up, down, or other similar terms such as upper, lower, aft, fore, vertical, horizontal, proximal, distal, etc. have been used for convenience purposes only and are not intended to imply any particular fixed direction or orientation.
