Abstract
Composites of a resin and texturized cellulosic or lignocellulosic fiber, and methods for forming the composites, are disclosed.
Claims16
A composite comprising a resin and at least about 2% by weight fiber, wherein
- the resin is selected from the group consisting of polyethylene, polypropylene, polystyrene, polycarbonate, polybutylene, thermoplastic polyesters, polyethers, thermoplastic polyurethane, PVC, and Nylon;
- the fiber is cellulosic or lignocellulosic paper that has been sheared to the extent that the internal fibers are substantially exposed.
A composite comprising polyethylene and fiber, wherein the fiber is cellulosic or lignocellulosic paper, at least about 50% by weight of said paper having been sheared to the extent that the internal fibers are substantially exposed.
A composite comprising a resin and fiber, wherein the composite has a flexural strength of at least 3,000 psi,
- the fiber is cellulosic or lignocellulosic paper that has been sheared to the extent that the internal fibers are substantially exposed, and
- the resin is selected from the group consisting of polyethylene, polypropylene, polystyrene, polycarbonate, polybutylene, thermoplastic polyesters, polyethers, thermoplastic polyurethane, PVC, and Nylon.
