  • Ballistic structure
    Patent number: 5035952
    Abstract: Ballistic structure comprising a solid combination of a metal first layer and a second layer consisting of a composite fiber material containing fibers with a tensile strength of at least 2 GPa and a modulus of at least 20 GPa, based on polyethylene with a weight average molecular weight of at least 4 * 10.sup.5 and a thermoplastic binding agent shows good ballistic properties if a binding layer is applied between the first layer and the second layer, which binding layer contains a modified polyolefin.
    Type: Grant
    Filed: May 5, 1989
    Date of Patent: July 30, 1991
    Assignee: Stamicarbon B.V.
    Inventors: Peter Bruinink, Wilhelmus A. R. M. Pessers
  • Combinations of polymer filaments or yarns having a low coefficient of friction and filaments or yarns having a high coefficient of friction, and use thereof
    Patent number: 5035111
    Abstract: The invention relates to combinations of polymer filaments or yarns of high tensile strength, high modulus and low coefficients of friction and filaments or yarns of high coefficients of friction. Combinations of this type, which have been produced in particular by core spinning the filaments or yarns of low coefficient of friction with filaments or yarns of high coefficients of friction or by twisting the two filament or yarn components, are suitable in particular for producing bulletproof wovens, knits and nonwovens.
