Abstract
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.
Claims26
An asymmetric tape, comprising:
- 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 comprising a first surface and an opposing second surface,
- wherein 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 including the first surface, the fiber rich portion including the second surface.
A system for impregnating at least one fiber roving with a polymer resin to form an asymmetric tape, the system comprising:
- a die comprising an impregnation section, the impregnation section comprising an impregnation zone configured to impregnate the roving with the resin, the impregnation zone comprising a plurality of contact surfaces,
- wherein a tape exits the die, the tape comprising the impregnated roving and having a resin rich portion and a fiber rich portion.
A method for impregnating at least one fiber roving with a polymer resin to form an asymmetric tape, the method comprising:
- flowing a polymer resin through a manifold assembly of a die, the manifold assembly comprising a plurality of branched runners;
- coating at least one fiber roving with the resin;
- and
- traversing the coated roving through an impregnation zone of the die to impregnate the roving with the resin,
- wherein a tape exits the die, the tape comprising the impregnated roving and having a resin rich portion and a fiber rich portion.
