Abstract: A compression molding device configured for the production of a part in composite material starting from a plate in composite with a thermoplastic matrix is described. The device comprises: a fixed support structure; an upper half-die provided with a first contoured surface corresponding to the profile of an upper surface of the part to be made; a lower half-die provided with a second contoured surface corresponding to the profile of a lower surface of the part to be made; holding means carried by the support structure and configured to hold the plate in a position interposed between the half-dies; and moving means for moving at least one of the half-dies from and towards the plate. The holding means comprise two or more releasable grippers gripping by friction distinct portions of the peripheral edge of the plate and configured to completely release or allow the complete release of the plate.

Abstract: A method is described for manufacturing a structural element in composite material extending along a straight or curvilinear longitudinal direction, having a Z-shaped cross section and comprising, in its final configuration, a central web and two flanges extending at a given final angle from opposite end portions of the web in respective directions opposite to one another; the method including the steps of: arranging a plurality of layers of composite material on a shaped portion of a forming mold; laminating the layers on the shaped portion so that the web is arranged, at least partially, in its final configuration, that a first flange is arranged in its final configuration at the final angle with respect to the portion of the web arranged in its final configuration, and that a second flange is arranged in its initial configuration at an initial angle distinct from, and greater than, said final angle with respect to the portion of the web arranged in its final configuration; moving a movable portion of the forming mold, which is movable with respect to a fixed portion of the forming mold, from a rest position to a bending position; displacing the second flange from the initial configuration into a final configuration in which it is at said final angle with respect to the portion of the web arranged in its final configuration; the step d) of displacing being carried out by means of the step c) of moving.
