    Abstract: A dicyandiamide crosslinked epoxy prepreg substantially free from dicyandiamide crystals is obtained by subjecting an epoxy composition containing dicyandiamide to elevated temperature to thereby form a substantially prereacted product, adding solvents if desired, desolvating, and then thermally advancing the prereacted product to the desired state of crosslinking to thereby form the prepreg.
