1. A composite sheet, comprising:
a plurality of extruded polymer ribbons having a ribbon length and a ribbon width, each polymer ribbon bonded to an adjacent polymer ribbon along adjacent lengthwise edges defining a lengthwise interface located between adjacent polymer ribbons,
each polymer ribbon comprising:
a polymer matrix; and a plurality of discontinuous fibers enveloped by and distributed throughout the polymer matrix,
wherein the discontinuous fibers are commonly aligned such that most of the discontinuous fibers are lengthwise oriented within 15 degrees of a common direction;
wherein the lengthwise interface between adjacent polymer ribbons comprises the polymer matrix of a first polymer ribbon continuously bonded to the polymer matrix of a second polymer ribbon adjacent to the first polymer ribbon along the lengths of the first and second polymer ribbons.
