ABSTRACT:
A thermoplastic powder slurry for making fiber reinforced composite structure prepregs having tack, drape and easy handleability is disclosed. A slurry of thermoplastic resin powder suspended in a solution of distilled water, a water-soluble polymer, a wetting agent, a biocide, a plasticizer and an antifoamer, which is used to impregnate suitable reinforcing fibers, either continuous or woven, makes a prepreg having tack, drape and easy handleability. The slurry may also include a viscosity reducer. The disclosed slurry can also be drawn into an adhesive tape or film.
