An adhesive is provided for bonding cyanate ester composite parts together which is also plateable with metal once chemically etched. The adhesive comprises a po lymeric matrix and a filler of cyanate ester polymer. The polymeric matrix comprises at least one polyepoxide resin and a curing agent, while the cyanate ester polymer filler is present in the adhesive as a powder. In practice, the present adhesive is applied to the surfac e of cyanate ester composite articles to be bonded and is allowed to cure at room temperature . Thereafter, the surface of the assembly is chemically etched and then plated with metal . The present adhesive enable the complete coverage of the cyanate ester composite assembly wi th the plated metal, including the adhesive bondlines. A cyanate ester resin structure assembled with the present adhesive composition may, upon plating, replace certain metalli c components in such applications such as aircraft, spacecraft, and automobiles given i ts highly conductive and comprehensive metallic coating. |
