ABSTRACT:
An apparatus used in connection with the construction of a duroplastic, fiber-reinforced article a fibrous web which includes continuously impregnating the web under subatmospheric pressure with a liquid, curable resin composition whose viscosity is gradually increasing. The prepreg thus obtained is covered on both its major surfaces by thin polymer sheets, then cut into the desired length, vacuum molded, pre-cured in the mold and finally cured outside the mold. Construction parts, car parts and boat bodies may thus be produced.
