| 20090246531 | PROCESS FOR THE PRODUCTION OF A STIFFENER THAT IS SCOOPED OUT IN THE SHAPE OF AN OMEGA AND CORE FOR THE PRODUCTION OF A STIFFENER THAT IS SCOOPED OUT IN THE SHAPE OF AN OMEGA - A process for obtaining a core for the production of a stiffener ( | 10-01-2009 |
| 20100269948 | THREE-DIMENSIONAL SURFACE WEAVING - A weaving method that makes it possible to directly produce three-dimensional structures having two-dimensional walls with corners, without requiring sewing or other joining between two edges. The weave is created by turning weft threads ( | 10-28-2010 |
| 20100319801 | SYSTEM FOR WEAVING A CONTINUOUS ANGLE - A weaving loom including a mechanism drawing-in threads, for insertion of picks, and for formation of a weaving shed, so as to render possible formation of a continuous angle or corner by a thread during weaving. The loom preferably also includes a vertical offset system, so that it is possible to weave a three-dimensional surfacic structure, the threads of which are continuous between the faces and at the level of the edges. The loom can be configured particularly for manufacture of continuous tridedral corners that are used as reinforcements for composite structures. | 12-23-2010 |
| 20110143085 | ASSEMBLY OF FIBROUS ELEMENTS FOR OBTAINING A PART MADE OF A COMPOSITE - A fiber structure that can be embedded in a matrix for obtaining a piece made of composite material, includes a first fiber element having a first support surface, at least one L-shaped fiber element having a base that is flattened against the support surface of the first fiber element at a junction zone and a wing that is not flattened against the first fiber element, and another fiber element having one part flattened against the wing of the at least one L-shaped fiber element. The elements are assembled by tapping fibers from a second surface of the first fiber element so as to form loops, at least certain fibers being oblique relative to the second surface, in a plane that is perpendicular to the junction zone, wherein certain loops of the oblique fibers protrude to the outside of the outer surface of a wing of at least one L-shaped fiber element. | 06-16-2011 |
| 20110180960 | METHOD FOR PRODUCING A COMPONENT MADE OF A COMPOSITE MATERIAL AND ASSOCIATED DEVICE - A process for manufacturing a piece made of composite material including a fiber preform that is embedded in a matrix, includes placing the preform in a first chamber that is delimited by a first semi-sealed wall, i.e., permeable to gas and impermeable to a product that is able to form the matrix, extracting the gases in a second chamber that is delimited by a second gas-tight wall and the first semi-sealed wall so as to obtain the diffusion of the product that is able to form the matrix in the preform, characterized in that it consists in using—as a first semi-sealed wall—at least one plate with a number of pipes of tapered shape that empty on either side of the at least one plate and at least one semi-sealed membrane that is superposed on the at least one plate. | 07-28-2011 |
| 20110272852 | METHOD FOR PRODUCING A CONCAVE-SHAPED IN PARTICULAR U-SHAPED PIECE IN A COMPOSITE MATERIAL AND DEVICE FOR CARRYING OUT THE SAME - A process for manufacturing a piece made of composite material with a hollow form and including a fiber preform ( | 11-10-2011 |
