Asymmetric fiber reinforced polymer tape

摘要

An asymmetric tape and a system and method for impregnating at least one fiber roving with a polymer resin to form an asymmetric tape are provided. The asymmetric tape includes a polymer resin, and a plurality of fibers embedded in the polymer resin to form a fiber reinforced polymer material. The fiber reinforced polymer material includes a first surface and an opposing second surface. The fibers are disposed in the fiber reinforced polymer material to form a resin rich portion and a fiber rich portion. The resin rich portion includes the first surface and the fiber rich portion includes the second surface.

1. An asymmetric tape, comprising:
a polymer resin; and a plurality of unidirectional continuous fibers of at least one fiber roving embedded and distributed within the polymer resin to form a single layer of fiber reinforced polymer material, the single layer of fiber reinforced polymer material comprising a first surface and an opposing second surface, the first surface and opposing second surface being formed together during formation of the asymmetric tape in a die and exiting the die as the single layer of fiber reinforced polymer material, wherein the continuous fibers are disposed in the single layer of fiber reinforced polymer material to form a resin rich portion and a fiber rich portion, the resin rich portion including the first surface, the fiber rich portion including the second surface, the resin rich portion and the fiber rich portion each including the identical polymer resin, and wherein the asymmetrical tape having the fiber reinforced polymer material has avoid fraction of approximately 2% or less.
