Abstract
The present invention pertains to a method for producing a frame for a working hull, specifically an aircraft fuselage wherein at least a part of the frame is in the form of a monolithic structure. The method includes the steps of draping unidirectional and multidirectional fabrics impregnated with resin on a form, placing inflatable bladders between the form and a counter form, closing a mold on the form, inflatable bladders and a counter-form, inflating the bladders to compress the fabrics and heat-set the resin impregnating the fabrics. Thereafter, the monolithic structure is removed from the mold.
