Abstract
A process for manufacturing pre-cured parts of composite material with green-applied stiffeners, comprising the lamination of superimposed pre-impregnated composite material sheets to obtain a base part ( ) and a second part ( ) intended to be bonded with it; curing the base part ( ); hot forming the laminate destined to form the second part ( ); removing the second part ( ) from the forming tool thereof and deposit it over the base part ( ), intercalating a structural adhesive sheet between both of them; closing the assembly of both parts inside a vacuum bag and loading said bag in an autoclave, carrying out a curing cycle of the second part ( ) under pressure and temperature, so that it is strongly adhered to the base part ( ). The invention is applicable to the field of aeronautics.
