Patent number: 5077338Abstract: A method of preparing a fiber reinforced elastomer by forming fibers therein in-situ and an elastomer made thereby are provided. In the method, a fiber forming material, preferably a high performance polymer, is dissolved in a compatible solvent to form a solvent/polymer mixture, and the mixture is added to the elastomer during compounding or mixing. The polymer is quickly dispersed into the elastomer, and the solvent rapidly evaporates. The shear of the mixer causes elongation of the polymer into fibers. The fibers may also be oriented by the shear of the mixer.Type: GrantFiled: August 23, 1990Date of Patent: December 31, 1991Assignee: The Goodyear Tire & Rubber CompanyInventors: William C. T. Tung, Deborah A. Tung, Mellis M. Kelley, Douglas C. Callander, 1
