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.

UHMWPE fiber and method to produce

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.

High lap shear strength, low back face signature UD composite and the process of making

Processes for preparing ultra-high molecular weight polyethylene ('UHMW PE') filaments and multi-filament yarns, and the yarns and articles produced therefrom. Each process produces UHMW PE yarns having tenacities of 45 g/denier to 60 g/denier or more at commercially viable throughput rates.

High tenacity high modulus UHMWPE fiber and the process of making

Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of highly oriented yarns are subjected to a treatment that enhances the surface energy at the yarn surfaces and are coated with a protective coating immediately after the treatment to increase the expected shelf life of the treatment.

UHMW PE fiber and method to produce

Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of partially oriented yarns are subjected to a treatment that enhances the surface energy at the fiber surfaces and are coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coated, treated yarns are then post drawn to form highly oriented yarns.

Process of making high tenacity, high modulus UHMWPE fiber

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced flexural properties, which correlates to low composite backface signature. The composites are useful for the production of hard armor articles, including helmet armor.

Rigid structure UHMWPE UD and composite and the process of making

Fibrous substrates and articles that retain their superior ballistic resistance performance after exposure to liquids such as sea water and organic solvents, such as gasoline and other petroleum-based products. The fibrous substrates are coated with a multilayer polymeric coating including at least two polymer layers wherein the first polymer and the second polymer forming said respective layers are the same and optionally comprise fluorine.

Method to create an environmentally resistant soft armor composite

High tenacity high modulus UHMW PE fiber and the process of making

Methods for modifying high tenacity fibers without reducing the physical strength properties of the fibers. More particularly, methods for modifying fibers with a plasma treatment or a corona treatment without reducing the physical strength properties of the fibers.

Surface treated yarn and fabric with enhanced physical and adhesion properties and the process of making

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties and retained or improved ballistic penetration resistance properties. The composites are formed from high tenacity fibers having a tenacity of at least about 33 g/denier at ambient room temperature after being modified by a plasma treatment or by a corona treatment, without tenacity loss due to said treatments.
