Abstract : A method for orienting non-continuous 3.5 mil glass fibers, 3/8 - 1/2 inch long, into a tape was developed. A converging V groove trough provided the mechanism of orientation. The non-continuous fiber tape was made on a Mylar carrier tape which was subsequently stripped before producing composites. Other methods which showed promise for orientation of smaller diameter fibers were mechanical and electrostatic flocking followed by combing. The 3.5 mil non-continuous fiber composites were relatively weak with with fracture occurring at end of the fiber through the resin, rather than through the fiber. An investigation of methods for orienting smaller diameter discontinuous fibers is planned in follow-on work to determine whether a high percentage of the strength of these fibers can be utilized in composites.
