Abstract: A method and apparatus for continuously processing fiber into an elastomeric component uses an expanding die (11, 11a) for orienting fibers in other than the processing direction of the extrusion. In one embodiment, an injection mold (50) is used with the expanding die (11), and in another embodiment, an extruder (30) is used with expanding die (11a). Processing parameters may be alteredto control the direction of orientation of fibers (20) in the elastomer component. Orientation of fibers (20) in an extrudate (17) is dependent on the processing speed viscosity of the elastomer, pressure of extrusion, the length l1 and l2 and height h1 and h2 of gate (12) and expansion cavity (14), respectively, of the expansion die (11, 11a).

Abstract: A method for molding short fiber/rubber composite articles having enhanced mechanical properties by aligning short reinforcing fibers during an injection molding process. The method comprises injecting a molding mixture through an injection gate arranged in a predetermined relationship to the molding cavity. The injection gate has a relatively small thickness in comparison to the thickness of the molding cavity. The fibers are associated with a first direction, generally parallel to the flow of the molding mixture as the molding mixture moves through the gate. As the molding mixture passes through the gate and into the cavity, the fiber direction is altered as the molding material fills the cavity.
