ABSTRACT:
Apparatus and methods are disclosed for producing fiber reinforced thermoplastic materials having substantially reduced amounts of breakage of the fibers and substantially increased tensile strength. In the preferred embodiment, relatively large diameter rollers are used to guide the filaments through a slurry bath of powdered resin, and spray header means are provided in the slurry bath to forcefully contact the filaments with the resin in the slurry.
