    Abstract: A spliced fiber tow (40) having a uniform density along its entire length is provided. The spliced fiber tow is manufactured by rarefying the ends (22, 32) of the two fiber tow segments to be joined, aligning the rarefied regions (26, 36) and then applying pressurized gas to entangle the filaments in the rarefied regions. An apparatus (50) for forming the spliced fiber tow includes a pair of rarefying blades (86, 92) and an entanglement element(58).

    Abstract: A dry fiber material that includes a fiber tow form having a planar shape of predetermined width and having first major exterior surface and a second major exterior surface, and a discontinuous layer of binder resin fused to at least the first major exterior surface of the fiber tow form. The binder resin is not tacky at room temperature and the amount of binder resin fused to the exterior surface of the fiber tow is less than 20% by weight, based on the weight of the fiber tow form.

    Abstract: A method of making a sized and resin-coated fiber tow for use in a fiber reinforced composite, the method comprising the steps of providing a fiber, contacting at least a portion of the fiber with a sizing slurry to form a sized and resin-coated fiber, the sizing slurry comprising 0.1-25% by weight of a sizing agent and 20-80% by weight of a matrix-resin powder in a solvent, based on the total weight of the sizing slurry, wherein the total solid content, including the sizing agent and the matrix-resin powder, of the sizing slurry is greater than 30 wt.%. The method further comprising drying the sized and resin-coated fiber at a temperature below the melting point of the matrix-resin powder, thereby forming a dried sized and resin-coated fiber and winding the dried sized and resin-coated fiber onto a spool.
