Abstract:
A method for fabricating a composite prepreg, comprising the steps of:(1) masking all but a first area of a prepreg ply fiber reinforcement substrate with a formulated impregnating resin in an uncured form and having a consistent fiber orientation throughout; (2) depositing a first impregnating resin material having a first predetermined dielectric constant to the prepreg ply fiber reinforcement substrate with a formulated impregnating resin in an uncured form and such that said first impregnating resin adheres to said first area; (3) masking all but a second area of the prepreg ply; and (4) depositing a second impregnating resin material having a second predetermined dielectric constant to the prepreg ply fiber reinforcement substrate with the formulated impregnating resin in an uncured form such that said second impregnating resin adheres to said second area.
