  • Patent number: 4495017
    Abstract: The present invention relates to a process for the continuous production of prepreg sheets unidirectionally arranged in parallel which involves contacting a plurality of fiber bundles arranged unidirectionally in parallel with each other with a solvent and continuously taking up the individual fiber bundle units under tension over curved surfaces of spreader bodies, such as cylinders while in a wet state, thereby spreading out said fiber bundles over the curved surfaces by means of said tension and subsequently drying the thus-spread out fibers. The invention also contemplates impregnating the dried fiber bundles with a specified quantity of molten resin to prepare the final prepreg resin-containing sheets.
