ABSTRACT:
A method for the manufacture of a fiber reinforced thermosetting resin molding material, which comprises feeding a liquid thermosetting resin composition to the surface of at least one transfer roller in rotation, causing the resin composition adhering to the surface to be spread in the form of particles by a spreading roller opposed across a gap to the transfer roller and rotated in the same direction as the transfer roller, allowing the spread said resin composition to be piled up in a state mixed with reinforcing fibers separately spread, and subsequently removing the entrapped air from the resultant pile thereby enabling the resin composition to wet out the reinforcing fibers in said pile.
