摘要： Prepregs comprising fibrous reinforcing material and a heat curable resin are provided with a backing sheet whose surface has been treated to increase the surface tension which enhances the bonding between the prepreg and the backing sheet, and reduces resin removal when the backing sheet is removed. The use of the treated backing sheet also provides improved tack between prepregs when assembled in a stack for molding after removal of the backing sheet.
