  • Prepreg forming apparatus
    Publication number: 20040238106
    Abstract: Fiber tow carrying a resin powder is dispensed from an unwind creel with the tow spread out using a comb. From here the tow is directed between a pair of bands and pressed onto the outer surface of a heated impregnation wheel. It is compressed against the wheel to melt the resin powder. The resin moves in a liquid state to be uniformly distributed across the tow strands. Pressure is applied by wheels pressing on the bands. The result is a composite tape that is cooled upon leaving the impregnation wheel and then wound onto a rewind drum or spool.
