Problem of maintaining good prepreg tack and drape has been solved by modification of addition polymide. Tack and drape are ability of prepreg to adhere to adjacent plies and to conform to desired shape during layup process. Alternate approach allows both longer life of polymer prepreg and processing of low-void laminates. It appears to be applicable to all addition polymide systems. Modified addition polymide takes advantage of reactive liquid plasticizer, monoethylphthalate, which is used in place of solvent. Because of low vapor pressure of reactive liquid, it is retained and, thereby, tack and flexibility of prepreg are retained.
