Abstract
This invention is related to a woven fibrous article which exhibits relatively low reductions in energy-to-break and tenacity on repeated impacts.
Claims43
A woven article of manufacture comprising a woven fibrous network of a plurality of polymeric fibers wherein the tenacity of said fibers in said network is equal to or greater than about 5 grams/denier (g/d), wherein the ratio of energy-to-break (lbf-in/in) of said article to the tensile strength (lbf) of said article is equal to or greater than about 0.105, and wherein the % change in energy-to-break of said article after the Impact Resistance Test is less than about 55% based on the energy-to-break of said article prior to testing and % change in the tensile strength of said article after said Impact Resistance Test is at least about 25% based on the tensile strength of said article before said testing.
The article of claim 24 wherein said fibers have crystalline domains and amorphous domain.
The article of claim w wherein said degree of crystallinity is equal to or less than about 66%.
