Abstract
Disclosed is a fiber-reinforced composite and methods and apparatuses for making the same. Some fiber-reinforced composites include a matrix material including a thermoplastic material and a non-woven fibrous region having a plurality of continuous fibers dispersed in the matrix material, wherein the width and the length of the non-woven fibrous region are substantially equal to the width and the length, respectively, of the liber-reinforced composite, wherein the non-woven fibrous region has a mean relative area fiber coverage (RFAC) (%) of from 65 to 90 and a coefficient of variance (COV) (%) of from 3 to 20, and wherein each of the plurality of continuous fibers is substantially aligned with the length of the fiber-reinforced composite.
