Abstract

PURPOSE: To obtain a prepreg sheet of uniform thickness by a method wherein a plurality of parallelly arranged hundles of fibers are wetted being or spraying a solvent, taken off continuously under tension along the curved surface of a column or a cylinder and said bundles of fibers are expanded, dried and impregnated with molten resin.
CONSTITUTION: Bundles 1 of fibers are supplied under the control of tension from a plurality of reels 2 which supply continuously a plurality of bundles of fibers , pass through an expanding device 3 and are dried sufficiently in an oven 4. On one hand, a fixed quantity of molten resin is supplied from a resin supply device 5 onto the mold-releasing paper fed off under tension and taken up by a take-up device 8 through a heating roll 7. In this manner, since the bundles of fibers are expanded in the form of a sheet in advance, dried sufficiently and then impregnated with molten resin, the prepreg which is constant in thickness and of a good apearance is obtained continuously without producing shortage of resin for impregnation and ununiformity of distribution of resin and fibers.
