Abstract: A system and method for constructing a composite structure using a multi-piece tool. The pieces are assembled, including making a connection, such as a mortise-and-tenon connection, between pieces using an adhesive mixed with an induction heatable material, such as iron filings having a unit size of between 5 microns and 600 microns, and an amount of between 5% and 50% by volume. Plies of a material are applied around the connection between the pieces, and the plies are cured to create the composite structure, which results in the pieces being trapped within the composite structure by the connection. The adhesive is exposed to electromagnetic induction from an electromagnetic induction coil which generates heat in the induction heatable material and thereby loosens the connection. The tool can then be disassembled by individually pulling at least some of the pieces from within the composite structure.
