  • UHMWPE fiber and method to produce
    Patent number: 11066765
    Abstract: Processes for preparing ultra-high molecular weight polyethylene fibers, and the fibers and articles produced therefrom. Exposed surfaces of the fibers are subjected to a treatment that enhances the surface energy at the fiber surfaces. Such treated surfaces are subsequently coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coating comprises at least one poly(alkyl-oxide) polymer.

  • BALLISTIC RESISTANT COMPOSITE MATERIAL
    Publication number: 20160281272
    Abstract: The present disclosure relates to a ballistic resistant composite 20 including a bimodal binder, the composite formable in a manner in which it is exposed to low pressure for a short duration of time and at a controlled temperature. More particularly, the bimodal binder of composite 20 allows the composite to be formed with a flat-bed laminator, for example, which may be less expensive than other processing methods, such as a steel belt press.
