Abstract
Apparatus for producing resin-impregnated fiber tow or strand in the form of prepreg tape. The apparatus includes unique coating wheels for sunface-coating the strand with molten, flowable resin and a kneading section to work the strand and disperse the molten resin uniformly among and between the individual fibers of the strand. The strand, after chilling, has good dimensional stability and is useful as prepreg in forming composite structures.
