ABSTRACT:
A bonding tool assembly (10) for supporting a composite part structure (11) during fabrication and curing processes, includes a bonding tool (12) and a plurality of fairing bars (14). The bonding tool (12) contains a support surface (16) upon which a composite part structure (11) is placed. The plurality of fairing bars (14) are placed completely around the periphery of the composite part structure (11) providing lateral support. The fairing bars (14) each contain a mating surface (18) which is placed directly upon the support surface (16) of the bonding tool (12). Each mating surface (18) contains a plurality of extended indexing protrusions (20) which form a distinct pattern and are secured by threaded fasteners (21). The support surface (16) contains a plurality of indexing recesses (22) that are configured to form the same pattern as the indexing protrusions (20) such that the fairing bars (14) and the bonding tool (12) are matable. Each fairing bar (14) also contains a plurality of magnets (24) that are located in pockets (26) slightly above the mating surface (18) of the fairing bars (14). The magnets (24) are secured in the pockets (26) by a heat-resistant adhesive (28). The fairing bars (14) magnetically adhere to the support surface (16) of the bonding tool (12) which is either adapted of a magnetically conductive material or contain magnetically conductive inserts (30).
