Abstract
A ballistic resistant article includes a first layer that has first unidirectional fibers disposed in a first polymer matrix. The first polymer matrix is composed of a thermoset polyurethane. A second layer is laminated to the first layer. The second layer includes second unidirectional fibers disposed in a second polymer matrix. The second unidirectional fibers are cross-oriented with respect to the first unidirectional fibers.
Claims13
A ballistic resistant article comprising:
- a first layer including first unidirectional fibers disposed in a first polymer matrix, the first polymer matrix being composed of a thermoset polyurethane derived from cycloaliphatic isocyanate and polyether polyol, wherein the polyether polyol is polytetramethylene ether glycol (PTMEG) and the thermoset polyurethane is 4,4′-dicyclohexylmethane diisocyanate (H12MDI);
- and
- a second layer laminated to the first layer, the second layer including second unidirectional fibers disposed in a second polymer matrix, the second unidirectional fibers being cross-oriented with respect to the first unidirectional fibers.
A ballistic resistant article comprising:
- a first layer including first unidirectional fibers disposed in a first polymer matrix, the first polymer matrix being composed of a thermoset polyurethane derived from cycloaliphatic isocyanate and polyether polyol, wherein the polyether polyol is polytetramethylene ether glycol (PTMEG) and the isocyanate is isophorone diisocyanate (IPDI);
- and
- a second layer laminated to the first layer, the second layer including second unidirectional fibers disposed in a second polymer matrix, the second unidirectional fibers being cross-oriented with respect to the first unidirectional fibers.
A ballistic resistant article comprising:
- a first layer including first unidirectional fibers disposed in a first polymer matrix, the first polymer matrix being composed of a thermoset polyurethane derived from cycloaliphatic isocyanate and polyether polyol, wherein the polyether polyol is polytetramethylene ether glycol (PTMEG) and the isocyanate is tolulene 2,4diisocyanate (TDI);
- and
- a second layer laminated to the first layer, the second layer including second unidirectional fibers disposed in a second polymer matrix, the second unidirectional fibers being cross-oriented with respect to the first unidirectional fibers.
A ballistic resistant article comprising:
- a first layer including first unidirectional fibers disposed in a first polymer matrix, the first polymer matrix being composed of a thermoset polyurethane derived from cycloaliphatic isocyanate, polyether polyol, and a blocking agent that caps the isocyanate, and the blocking agent selected from the group consisting of oxime, pyrazole, malonate, and combinations thereof;
- and
- a second layer laminated to the first layer, the second layer including second unidirectional fibers disposed in a second polymer matrix, the second unidirectional fibers being cross-oriented with respect to the first unidirectional fibers.
