摘要
The method of the present invention produces a tape of high performance reinforcing fibers having improved alignment between the fibers and improved maintenance of that alignment in processing and molding applications. The method involves contacting one or more of the continuous high performance reinforcing fibers with a polymer impregnated mat. The polymer is compatible with any polymeric material used in the subsequent processing or molding applications. The contacting is performed with the high performance fibers under tension, and the tension is removed when the fibers are properly aligned into a tape in contact with the impregnated mat. The tape material can be used with various molding compounds such as sheet molding compounds and high reinforcement content molding compounds and thermoplastic molding materials wherein the molding compound is contacted with the tape product. The contacting can be performed during formation of the molding compound or the tape material can be applied to an already formed molding compound during compression molding.
