A mechanically fastened permanent or detachable joint between two or more parts (21, 23, 25, 41), at least one of them made of a composite material, preferably carbon fibers impregnated with thermoset resin, with continuous plies from the full-composite area along the joint area (15) and including a
A mechanically fastened permanent or detachable joint between two or more parts (21, 23, 25, 41), at least one of them made of a composite material, preferably carbon fibers impregnated with thermoset resin, with continuous plies from the full-composite area along the joint area (15) and including a metal reinforcement, preferably made of titanium, in the joint area (15), the joint area (15) thickness being increased in the thickness of said reinforcement plus the eventual additional composite plies laid only on the reinforced area. The metal reinforcement may consist of one or more metal foils or sheets (31) interleaved between the composite plies or one or more metal plates (33) embedded between two of the composite plies.

The invention claimed is: 1. A mechanically fastened lap joint between two or more parts each made with plies of a composite material wherein said parts are superimposed on each other at the location of the joint and at least one of said parts comprises a metal reinforcement ply between plies of composite material in the joint area and its plies of composite material are continuous along the joint area so that its thickness is increased in the joint area by the thickness of said metal reinforcement. 2. A mechanically fastened lap joint between two or more parts according to claim 1, wherein said at least one of said parts (21, 23, 25, 41) also comprises a composite reinforcement in the joint area (15) consisting of additional composite plies laid only in the joint area (15) increasing additionally the thickness of the joint area (15) in the thickness of said composite reinforcement. 3. A mechanically fastened lap joint between two or more parts according to claim 1, which comprises at least three parts (21, 23, 25) made with plies of a composite material. 4. A mechanically fastened lap joint between two or more parts according to claim 1, wherein one part (41) having a metal reinforcement has a lug shape in the joint area (15) and the joint is formed by a fastening passing through the lug hole (45). 5. A mechanically fastened lap joint between two or more parts according to claim 1, wherein the joint is formed by a permanent fastening. 6. A mechanically fastened lap joint between two or more parts according to claim 1, wherein the joint is formed by a detachable fastening. 7. A mechanically fastened lap joint between two or more parts according to claim 1, wherein said metal reinforcement consists of one or more metal foils or sheets (31) interleaved between the plies of the composite material. 8. A mechanically lap fastened joint between two or more parts (21, 23, 25, 41) according to claim 1, wherein said metal reinforcement consist of one or more metal plates (33) embedded between two plies of the composite material. 9. A mechanically fastened lap joint between two or more parts (21, 23, 25, 41) according to claim 1, wherein the composite parts are made of carbon fibres impregnated with thermoset resin. 10. A mechanically fastened lap joint between two or more parts according to claim 1, wherein the metal reinforcement is made of titanium. 11. A mechanically fastened lap joint between two or more parts according to claim 1, wherein the joint is fastened by bolts.
