  • Patent number: 6438935
    Abstract: A process and apparatus are provided for the manufacture of a composite fibrous strand comprising glass fibers. Glass fibers and an additive fibrous material (e.g., thermoplastic polymeric fibers) are each introduced separately into a substantially rotationally symmetric zone that is closed circumferentially except for a longitudinal introduction locale. The glass fibers and the fibers of the additive fibrous material are subjected to a vortex to form a homogeneous composite fibrous strand. Good admixture of the fibrous components is made possible thereby facilitating the ultimate production of composite articles wherein the glass fibers are disposed as reinforcement in a highly uniform manner. Such homogeneity and uniformity provides improved mechanical properties to the end user.
