摘要： A process for preparing a cured composite material useful for radio frequency filter applications comprising the steps of: (a) providing a curable thermoset epoxy resin composition comprising (i) at least one epoxy resin; (ii) at least one toughening agent; (iii) at least one hardener; and (iv) at least one filler; (b) curing the curable thermoset epoxy resin composition of step (a) to form a cured composite; wherein the curable thermoset epoxy resin composition upon curing provides a cured composite product with a balance of properties comprising Tg, coefficient of thermal expansion, tensile strength, thermal conductivity; and having a density of less than 2.7 g/cc; and (c) coating at least a portion of the surface of the cured composite of step (b) with an electrically conductive metal layer to form a metalized coating on at least a portion of the surface of the cured composite. The cured composite material may be useful as a radio frequency cavity filter body housing for radio frequency filter applications.
