Abstract:
Tooling for on-site repairs of a composite structure, having an outer surface and a concave recess previously machined in a surface of the composite structure, for high pressure polymerization of a non-polymerized composite part including a shape that matches that of the concave recess, the tooling comprising:a bladder including a peripheral edge capable of being fastened around the non-polymerized composite part such that it forms a hermetic leaktight seal between the peripheral edge and the composite structure outer surface;a stack of plates including at least two plates interposed with the bladder and the non-polymerized composite part, wherein the plate proximate to the bladder has a surface area greater than a surface area of the plate proximate to the non-polymerized composite part, whereby pressure on the non-polymerized composite part is increased;means for connecting the bladder to an external source of negative pressure; andmeans for heating the non-polymerized composite part.
