摘要： Fiber-reinforced recycled thermoplastic composites and methods for their manufacture are presented. In a preferred embodiment, the thermoplastic composite incorporates a matrix of recycled thermoplastic and a plurality of high modulus fibers, with the recycled thermoplastic including polyethylene, polypropylene, nylon, PET and styrene-butadiene rubber, and the high modulus fibers including glass fibers, natural fibers, carbon fibers, and aramid fibers. Preferably, each of the high modulus fibers have a minimum length of approximately null of an inch and a modulus of approximately one million psi.

摘要： This invention is based upon the discovery that cyclized polyisoprene polymers can be incorporated into tire tread compounds to improve traction, treadwear, and resistance to tear. It is further based upon the discovery that cyclized polyisoprene polymers can be blended with halobutyl rubber and/or natural rubber and can be utilized in tire innerliner formulations. The present invention more specifically discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidwalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer. The present invention further discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, an innerliner, at least one ply extending from bead to bead and sidwalls extending radially from and connecting said tread to said beads, wherein said innerliner is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer selected from the group consisting of natural rubber and halobutyl rubber.
