    摘要: 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 (12) and superimposing the spaced array (40) of separate yarns (12) onto a spread tow (62) of reinforcing fibers. The resulting planar mixed yarn is then gathered into a tow (135) having a non-uniform distribution of thermoplastic fibers throughout the tow. The tow (135) 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.
