Hybrid bicomponent fibers represent a promising class of intermediate materials that facilitate the high-volume production of thermoplastic composites. Compared to existing intermediate materials, bicomponent fibers allow for very short cycle times through the minimization of flow lengths during consolidation, while retaining the high formability of dry fibrous preforms. As a method to manufacture such hybrid bicomponent fibers, we propose a kiss-roll coating process in-line with glass melt spinning. A high-speed study is presented to prove the feasibility of the process to yield fiber volume fractions appropriate for use in advanced structural composites. The influence of the fiber speed, the polymer concentration in the coating solution, and the radius and peripheral speed of the kiss-roll on the resulting coating thickness are assessed via a two-level full factorial parameter study. Finally, some considerations for the realization of a high-speed coating stage in-line with glass melt spinning are given Show more
