<p>A system and method for uniformly coating one or more fibers (10) with particles of a material is described. The method uses a vibrator preferably an acoustic speaker (17b) in a housing (17c) to fluidize the particles (P1) in a chamber (17 or 30) to deposit them on spread fibers (10b). The fibers can be in the form of a tow of fibers. After the particles are coated on the fibers, the particles can be bonded to the fiber such as by using a heater (19). The resulting product has a uniform deposit of the particles and in the case of the tow of fibers can serve as a prepreg for laminate structures to be produced from the coated tow of fibers.</p>
