Method for integrating a fitting between the wings of a profile

A method for integrating a laminate composite fitting fitted between two wings of a laminate composite profile comprising steps of:

• I) obtaining a laminate preform of a fitting comprising a fibrous reinforcement impregnated with a thermosetting resin, the laminate preform of the fitting comprising two flanges intended to be inserted in contact between the two wings of the laminate composite profile and a rib extending between the two flanges and integral therewith;
• II) precuring the laminate preform of the fitting to obtain a partially polymerized laminate preform of the fitting;
• III) laying up of a profile preform of the laminate composite profile so that fibers impregnated with a thermosetting resin comprised the two wings of the profile preform of the laminate composite profile are laid up over the two flanges of the partially polymerized laminate preform of the fitting;
• and
• IV) completely polymerizing an assembly comprising the profile preform of the laminate composite profile and the partially polymerized laminate preform of the fitting while maintaining into contact the two flanges of the laminate preform of the fitting with the two wings of the profile preform of the laminate composite profile;
• wherein the laminate preform of the fitting comprises two half-preforms made by a layup of fibers pre-impregnated with the thermosetting resin, the two half-preforms being assembled by precuring during step II) along a contact plane located in the rib.
