ABSTRACT:
The invention is directed to a process for preparing a blended tow of thermoplastic and reinforcing fibers. The process of the invention includes the steps of forming a substantially planar spaced array of thermoplastic multifilament yarns and superimposing the spaced array of separate yarns onto a spread tow of reinforcing fibers. The resulting planar mixed yarn is then gathered into a tow having a nonuniform distribution of thermoplastic fibers throughout the tow. The tow is useful in forming fiber-reinforced composite articles by shaping the tow into a desired form and then heating the shaped tow to melt the thermoplastic fibers which, in turn, form a plastic matrix which is reinforced by the reinforcing fibers.
