METHOD FOR BONDING A FACING SKIN TO A FREEFORM-FABRICATED COMPOSITE CORE

摘要

A method for bonding a facing skin to a freeform-fabricated core of a composite article generally comprises the steps of: fabricating a core using a free-form fabrication machine, said core including an internal reinforcing structure with a plurality of integral structural elements formed at or near a surface of the core; applying an adhesive to the surface of the core; placing a facing skin against the adhesive to form a composite lay-up; and curing the composite lay-up to form the composite article, with the adhesive passing through or around the integral structural elements, thus enhancing the bond between the facing skin and the freeform-fabricated core.
