ABSTRACT:
A novel method for generating orientation of short fibers in the matrix of a composite material allows for production of complex high strength components. With state of the art technologies short fibers can be oriented only by elongational flows and these are generally applicable only to extrusion products. The invention is based on the fundamental discovery that short fibers can be oriented by relative movement against a finer three-dimensional isotropic network. Gel networks are of molecular level and satisfy this scaling requirement even for whiskers. The process involves mixing-in the fibers with a gel, pouring (injecting) the mixture into a mold and then orienting the fibers by moving them relative to the gel network. The movement can be driven by sound waves. When orientation is accomplished, the gel is solidified forming the matrix of the composite.
