Embodiment Construction

[0022] The invention relates to the field of manufacturing structures from composite materials starting from stacking plies consisting of reinforcing fibers pre-impregnated with a polymeric resin and having a defined orientation. According to the present invention, the consolidation process under the action of pressure and temperature achieves: compaction of the material, removal of excess resin and volatiles, and consolidation (by means of cross-linking of the resin if thermosetting, or by cross-linking of the resin if thermoplastic , then by means of welding), so that the panel has high mechanical properties.

[0023] like Figures 1a to 1c Illustratively, three schematic stages of a method generally employed for forming stringers or spars according to the prior art are described below.

[0024] In the first stage, if Figure 1a Observably in , the flat laminates 1, 2 - from which the stringers or stiffeners are obtained, said laminates 1 and 2 having been pre-stacked and c...

Abstract

The invention relates to a device for manufacturing three-dimensional parts, such as a composite-material beam composed of reinforcing fibres preimpregnated with polymer resins, from unpolymerized, precut and taped laminated articles (21, 22), said device comprising a headstock (15) which in turn comprises a train of rollers (17), said headstock (15) being able to move longitudinally along a fixed bench, such that, when said headstock (15) moves, the train of rollers acts on the unpolymerized laminated articles (21, 22), compressing and shaping them, thus imparting to the laminated articles (21, 22) their final form in a single pass. Said laminated articles (21, 22) are thus ready for subsequent integration thereof. The invention also relates to a method for manufacturing three-dimensional parts such as a composite-material beam.

Description

technical field [0001] The invention relates to a device for producing composite material components, in particular for aircraft, and to a method for producing said composite material components. Background technique [0002] Based on weight savings and improved mechanical properties, the extensive application of new composite materials in aerospace primary structures has become an important method of structural optimization and is therefore becoming one of the main goals in the design and manufacture of new generation aircraft. [0003] Numerous applications of such composite materials have been achieved due to improved techniques and equipment for the automated stacking and cutting of laminates / laminates obtained from plies consisting of reinforcing fibers pre-impregnated with polymeric resins. become possible. However, the automation of manufacturing processes is almost exclusively limited to the production of large two-dimensional laminates (large airfoils such as wings...
