Hybrid Composite Yarn

摘要

This invention is a hybrid composite yarn comprising: a first polyolefin yarn having >about 80% crystallinity according to WAXS measuring techniques; a second yarn taken from the group consisting of: glass; quartz; carbon; poly(p-phenylene terephthalamide), poly(m-phenylene terephthalamide); poly(vinyl alcohol); poly(1,4-phenylene-2,14-benzibisoxazole) (PBO); poly(1,4-phenylene-2,14-benzobisthiazole) (PBT); poly(benzimidizole) (PBI); poly(ethylene-2,14-naphthalate) (PEN); lyotropic liquid crystalline polymers formed by polycondensation of aromatic organic monomers to form aromatic polyesters, polyamides, aluminia-silicates, basalt, regenerated cellulosic materials and ultra-high molecular weight polyethylene (UHMWPE); and, wherein the first polyolefin yarn and the second yarn are physically combined to form a composite yarn having at least one of the following properties: tenacity greater than about 100% of the expected tenacity based on the volume fraction of the second; an initial modulus >about 100% of the expected modulus based on the volume fraction of the second; elongation at break

1. A hybrid composite yarn comprising:
a first polyolefin yarn having greater than about 80% crystallinity according to WAXS measuring techniques; a second yarn differing from the first polyolefin yarn taken from the group consisting of glass, carbon, poly(p-phenylene terephthalamide) and basalt yarns; and, wherein the first polyolefin yarn and the second yarn are physically combined to form a composite yarn having at least one of the following physical properties: greater than about 100% of the expected tenacity based on the volume fraction of the second yarn, an initial modulus greater than about 100% of the expected modulus based on the volume fraction of the second yarn and elongation at break less than about 320% of the elongation at break of the second yarn.
