Claims16
A unidirectional tape comprising:
- a unidirectional fiber layer comprising a plurality of unidirectional fibers and a first polymer;
- and a
- a discontinuous coating layer comprises a plurality of discontinuous coating regions on at least one side of the unidirectional fiber layer, wherein the discontinuous coating layer comprises a second polymer.
A method of producing a unidirectional tape comprising:
- preparing a unidirectional fiber layer comprising a plurality of unidirectional fibers and a first polymer;
- discontinuously coating at least one side of the unidirectional fiber layer with a plurality of particles comprising a second polymer;
- heating the plurality of particles such that the plurality of particles coalesce into a plurality of discontinuous regions on the at least one side of the unidirectional fiber layer;
- and
- pressing the at least one side of the coated unidirectional fiber layer to form the unidirectional tape.
