Abstract: A method for manufacturing pieces of composite material having varied thicknesses is disclosed. The method includes a first stacking stage and a second forming and drying stage. In the second stage, a forming tool, which is adapted to the configuration of the piece, except in the zone affected by the change in thickness, is used. In the first stage, one or more pre-forms of the piece are stacked successively with some cloths having the dimensions needed for producing the change of thickness, some laminates of a peelable material, and some supplementary cloths in such a way that the resulting layers have the thickness needed to be adapted to the forming tool. At the end of the second stage, laminates resulting from the supplementary cloths and laminates of a peelable material are removed.

Abstract: Aircraft component, such as an aircraft wing, that comprises at least one panel (11) of a composite material formed by a skin (13) and at least a stiffening stringer (15) configured by a web (17) and a foot (19) bonded to said skin (13); the stringer (15) having a run-out zone inside said panel (11) subjected to a high load level; the stringer (15) having a web (17) of decreasing height in said run-out zone and a foot (19) having a first section (31) of variable width from an initial value W1 to a final value W2 and a second section (33) with a width W2 in said run-out zone; the foot (19) and the web (17) of said stringer (15) having a decreasing thickness in said run-out zone for improving the load transfer from the stringer (15) to the skin (13).

Abstract: An object (4) to be taped in carbon fiber has a first taping strip (1), beside which a second taping strip (2) is arranged, leaving between both of them a separation between strips (3), having an automatic taping machine (5). One light generator block (7) produces a light mark (6) that is applied to the separation (3) area; an image capture block (8) captures the light mark (6), being analyzed by a processing and control block (10). If the separation measure (ML, MR) between strips (3) is within an accepted tolerance range (T), then the taping method continues without change. But if the value of the measure (ML, MR) is far greater than the tolerance (T) allowed, or it is far less than the tolerance (T) allowed, then signals (SR, SL) are generated and sent to the position control (10) to correct the position to the right or to the left, until obtaining a new measure (ML, MR) value that meets the allowed tolerance (T).
