Definitions

  • United States Patent No. 4,859,393 issued August 22, 1989 on the application of Yang and Chiou, discloses a process for making p-aramid yarns said to have a high elongation at break.
  • the present invention provides a p-aramid ballistic structure which utilizes yarns having a combination of especially high tenacity and elongation to break.
  • the ballistic structure is laminated and comprises a plurality of fabric layers made from that p-aramid yarn exhibiting an elongation to break of greater than 4.0%, a modulus of less than 600 gpd, and a tenacity of greater than 23 gpd.
  • P-aramid fibers are extremely strong on a weight basis and provide good ballistic protection with a relatively high
  • There has been great effort expended in developing yarns and fabrics with improved ballistic performance because even small improvements save the lives of users of ballistic garments.
  • Each improvement is hard- won and highly significant.
  • the present invention represents an improvement in ballistic performance, measured by V5 0/ of about 5%.
  • the kind of fabric or weave to which the yarn is applied is not important to realize the benefit of the invention. That is, for any fabric or weave pattern, ballistic performance obtained using the yarn of this invention will be improved over that obtained using a similar yarn having a lower toughness due to lower tenacity or lower elongation to break.
  • Body armor using ballistic fabrics is usually made with several layers of fabric laid or sewn together to yield a laminated structure.
  • the laminated structure can include additional layers of other materials such as decorative or moisture resistant covering fabrics or other shock absorbing materials.
  • the form of the laminated structure and whether or not it includes additional layers of other materials is not important to realization of the improved ballistic performance of this invention. It has been discovered that the effectiveness of any ballistic structure will be improved by utilization of yarn having relatively higher tenacity and/or elongation to break instead of similar yarn having relatively lower tenacity and/or elongation to break. Test Methods
  • Ballistic tests of the composite samples are conducted in accordance with MIL-STD-662e as follows: A lay-up to be tested is placed in a sample mount to hold the lay-up taut and perpendicular to the path of test projectiles.
  • the projectiles are 17-grain fragment simulating projectiles (MIL-P-46593) , except where indicated otherwise, and are propelled from a test barrel capable of firing the projectiles at different velocities.
  • the first firing for each lay-up is for a projectile velocity estimated to be the likely ballistic limit (V 50 ) •
  • the next firing is for a projectile velocity of about 50 feet per second less in order to obtain a partial penetration of the lay-up.
  • the next firing is for a velocity of about 50 feet per second more in order to obtain a complete penetration.
  • subsequent velocity increases or decreases of about 50 feet per second are used until enough firings are made to determine the ballistic limit (V5 0 ) for that lay-up.
  • the ballistic limit (V 50 ) is calculated by finding the arithmetic mean of an equal number of five of the highest partial penetration impact velocities and five of the lowest complete penetration impact velocities, provided that there is not more than 125 feet per second between the highest and lowest individual impact velocities.
  • Tenacity is reported as breaking stress divided by linear density. Modulus is reported as the slope of the initial stress/strain curve converted to the same units as tenacity. Elongation is the percent increase in length at break. Both tenacity and modulus are first computed in g/denier units which, when multiplied by 0.8826, yield dN/tex units. Each reported measurement is the average of 10 breaks.
  • Tensile properties for yarns are measured at 24°C and 55% relative humidity after conditioning under the test conditions for a minimum of 14 hours. Before testing, each yarn is twisted to a 1.1 twist multiplier (for example, nominal 1500 denier yarn is twisted about 2.1 turns/inch) . Each twisted specimen has a test length of 25.4 cm and is elongated 50% per minute (based on the original unstretched length) using a typical recording stress/strain device.
  • the twist multiplier (TM) of a yarn is defined as:
  • the dope was deaerated under vacuum and spun through a spinneret having 672 capillaries of 2.5 mil (0.0635mm) diameter. Spinning was at a dope temperature of about 71°C directly through an air gap.0.64 cm in length and then into a spin tube together with coagulating liquid which was an aqueous solution of 8% by weight sulfuric acid maintained at 20°C. The spin stretch factor was 6.3.
  • the coagulated yarn was forwarded to a water-washing stage, to a neutralization stage, to a drying stage on a pair of internally steam-heated rolls with surface temperature of 150°C, and then to windup on bobbins at a moisture content of about 12 weight percent.
  • Yarn tension during washing/neutralization was 0.2 to 0.4 grams per denier (gpd) and during drying was 0.05 to 0.2 gpd.
  • the resulting yarn was 1000 denier (1111 dtex) and 1.5 denier per filament (dpf) (1.67 dtex per filament).
  • the yarn exhibited an elongation to break of 4.3%, a modulus of 450 gpd, and a tenacity of 24 gpd.
  • Test fabrics were made using the yarn of this example and control test fabrics were made using commercially-available aramid yarn sold by E. I du Pont de Nemours & Co. under the trademark designation Kevlar® 29.
  • the control yarn exhibited an elongation to break of 3.4%, a modulus of 605 gpd, and a tenacity of 23 gpd.
  • the control yarn was, also, 1000 denier and 1.5 denier per filament.
  • the fabrics were plain weave with a basis weight of about 244 g/m 2 (7.1 oz/yd 2 ) and a construction of about 29 x 26 (W x F/inch) . Finish was removed from each of the fabrics by washing in water with detergent and rinsing in water.
  • PPD-T yarn was spun by the same process as was used in Example 1, above, except that the spinneret had 1000 capillaries of 2.5 mil (0.0635 mm) diameter to produce a yarn of 1500 denier (1667 dtex) and 1.5 dpf. This yarn exhibited an elongation to break of 4.8%, a modulus of 365 gpd, and a tenacity of 23.3 gpd.
  • Fabrics again, were made using the yarn of this example and control test fabrics were made using commercially-available aramid yarn sold by E. I du Pont de Nemours & Co. under the trademark designation Kevlar® 29.
  • the control yarn exhibited an elongation to break of 3.6%, a modulus of 560 gpd, and a tenacity of 23 gpd.
  • the control yarn was, also, 1500 denier and 1.5 denier per filament.
  • the fabrics were plain weave with a basis weight of about 325 g/m 2 (9.6oz/yd 2 ) and a construction of about 24 x 24 (W x F/inch) . Finish was removed from each of the fabrics by washing in water with detergent and rinsing in water.
  • Poly(p-phenylene terephthalamide) (PPD-T) fibers having high tenacity and high elongation were spun as described in United States Patent Application Serial No. 07/673,552, filed March 8, 1991.
  • the PPD-T had an inherent viscosity of 6.3 dL/g.
  • the PPD-T was dissolved in 100.1% sulfuric acid to a concentration of 19.4 weight percent.
  • the dope was deaerated under vacuum and spun through a multiple-orifice spinneret having capillaries of 2.0 mil (0.051mm) diameter.
  • Spinning was at a dope temperature of about 71°C directly through an air gap 0.64 cm in length and then into a spin tube together with coagulating liquid which was an aqueous solution of 8% by weight sulfuric acid maintained at 2°C.
  • the spin stretch factor was 4.14.
  • the coagulated yarn was forwarded to a water-washing stage, to a neutralization stage, to a drying stage on a pair of internally steam-heated rolls with surface temperature of 125°C, and then to windup on bobbins at a moisture content of about 12 weight percent.
  • Yarn tension during washing/neutraliza ion was 0.2 to 0.3 grams per denier (gpd) and during drying was 0.2 to 0.3 gpd.
  • the resulting yarn was 1500 denier (1667 dtex) and 1.5 denier per filament (dpf) (1.67 dtex per filament). It exhibited an elongation to break of 4.2%, a modulus of 510 gpd, and a tenacity of 26.2 gpd.
  • Test fabrics were made using the yarn of this example and control test fabrics were made using commercially-available aramid yarn sold by E. I du Pont de Nemours & Co. under the trademark designation Kevlar® 29.
  • the control yarn exhibited an elongation to break of 3.4%, a modulus of 605 gpd, and a tenacity of 23 gpd.
  • the control yarn was, also, 1500 denier and 1.5 denier per filament.
  • Two fabrics were woven: one was a plain weave with a basis weight of about 339 g/m 2 (10.0 oz/yd 2 ) and a construction of about 24 x 24 (W x F/inch) ; and the other was a 2x2 basket weave with a basis weight of about 474 g/m 2 (14.0 oz/yd 2 ) and a construction of about 36 x 35.
  • Finish was removed from each of the fabrics by washing in water with detergent and rinsing in water.
  • Example 2 a test fabric was woven the same as that used in Example 3.
  • the ballistic test resulted in V5 0 , for the test fabric, of 548.2 m/s and V5 0/ for the control fabric, of 520.0 — an improvement of 5.4%.
