Method for pre-preg manufacturing

A method of making a plurality of composite parts, the method comprising:

• covering a mold tool for a composite part with a parting film, the parting film comprising a polymer sheet and a pressure sensitive adhesive, the parting film being positioned so that the polymer sheet is between the mold tool and the pressure sensitive adhesive;
• forming a first composite part by carrying out (i) a laying up process comprising laying up at least one layer of pre-preg on the parting film covering the mold tool to form the first composite part, the pre-preg comprising an adhesive;
• and (ii) removing the first composite part from the parting film;
• and
• repeating (i) and (ii) to form an additional composite part, the first composite part and the additional composite part being formed without removing the parting film from the mold tool,
• wherein the pressure sensitive adhesive comprises a material chosen from adhesives of acrylic resin, polyurethane, rubber, styrene-butadiene-styrene copolymer, ethylene vinyl acetate, styrene block copolymers, and combinations thereof.
