  • Method for the impregnation of filament wound structures with thermoplastic binders
    Patent number: 4865787
    Abstract: Filament wound or dry lay-ups of structural shapes are impregnated with a binder of thermoplastic resin. Impregnation is achieve by adding a polymer solution to a centrifuge containing reinforcing material. The centrifuge is spun at high rotational speed. Solution is metered into the centrifuge and contacts the inner surface of the reinforicng material. A preheated carrier gas flow is circulated in the centrifuge using baffles, then released to a solvent recovery system. Alternatively, vacuum drying to recover solvent can be used.
