Abstract
The invention is directed to a 'Self-Reinforced Composite' (SRC) made of recycled thermoplastic polymers, methods and an apparatus for their manufacture. In one embodiment of the invention, the SRC is a self-reinforced composite comprising (a) a fiber comprising a first recycled thermoplastic polymer and having a Young's modulus at least about 500 MPa and (b) a matrix comprising a second recycled thermoplastic polymer. In one aspect of the invention, the source mixture is recycled immiscible thermoplastic polymers, obtained from the waste stream in the carpet and automotive industries. In another embodiment of the invention, the method for making the self-reinforced composites, comprising the steps of (a) melt-blending recycled immiscible polymers, (b) phase-migration fiber spinning the recycled immiscible polymers to form a fiber having a first recycled thermoplastic polymer substantially surrounded by a second recycled thermoplastic polymer, and (c) drawing the fiber to form a high modulus fiber.
