Abstract
A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.
Claims21
A method for producing a polymer construct comprising:
- coextruding a first polymer material with a second polymer material to form a coextruded polymer film having discrete overlapping layers of polymeric material that each extend the entire length of the coextruded polymer film;
- multiplying the overlapping layers by dividing the coextruded polymer film into portions and stacking the portions to form a multilayered composite film;
- separating the first polymer material from the second polymer material to form a plurality of first polymer material fibers having a rectangular cross-section;
- and
- adhering the first polymer material fibers together to form the polymer construct.
