Abstract
A method of preparing resin sheets reinforced by glass and carbon strands is described in which the glass strands are passed through a resin bath. The glass strands are passed through a die as they emerge from the bath to control their resin content and wound on a mandrel. The carbon strands are passed directly into the die and are wetted by the resin in the die and on the mandrel. The glass and carbon strands are laid on the mandrel with resin to provide a resin sheet containing 5 to 70 percent glass by weight and 60 to 5 percent carbon strand by weight.
