Abstract
Prepregs and laminates made from resin compositions having a free resin portion and a resin impregnated reinforcing material portion where the resin includes one or more base resins and one or more high Dk materials wherein the one or more high Dk materials are present in the resin composition in an amount sufficient to impart the resin composition with a cured DkW that matches the DkWR of a resin impregnated reinforcing material to which the resin composition is applied to within plus or minus (±) 15%.
Claims18
A prepreg comprising:
- an at least partially cured resin impregnated reinforcing material portion;
- and
- a free resin portion wherein the resin includes at least one high dielectric constant material, the free resin portion having a dielectric constant DKw and the resin impregnated reinforcing material portion having a dielectric constant DKWR wherein the high dielectric constant material is incorporated into the resin in an amount sufficient to match the DKWR with the DKW such that the DKWR and DKw differ by no more than (±) 15%.
