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 |
20120138746 | OBLIQUE PANEL AT THE REAR OF A CENTRAL BOX OF AN AIRCRAFT FUSELAGE - An aircraft structure includes a wing spar ( | 06-07-2012 |
20120261069 | AUTOMATED DRAPE-FORMING DEVICE - The invention relates to an automated device for implementing a drape-forming step to form a laminated fibrous preform, which is then impregnated with resin to produce a part made of composite material. The invention relates more particularly to the production of preforms for manufacturing parts such as panels, in particular very thick panels, that extend basically in two dimensions. The device of the invention comprises a manipulator ( | 10-18-2012 |

20130206324 | Method for producing a central wing box - A method for producing a central wing box having an upper panel, a lower panel, a front spar and a rear spar, the upper edges of said spars approximately parallel to an axis Y being connected by the upper panel, and the lower edges of said spars approximately parallel to the axis Y being connected by the lower panel. The method includes producing at least one panel and at least one spar from composite material in one piece. | 08-15-2013 |
20130263966 | THREE-DIMENSIONAL SURFACE WEAVING - A weaving process for direct manufacture of three-dimensional structures with bidimensional walls with corners, without the need for sewing or other assembly between two ridges. The weaving is made by transforming weft threads into warp threads for making at least one face. The process is particularly adapted for the weaving of reinforcing elements for composite structures of corner fitting type. | 10-10-2013 |

20100105217 | DEFECTIVITY OF POST THIN LAYER SEPARATION BY MODIFICATION OF ITS SEPARATION ANNEALING - A method of detaching two substrates at the embrittlement zone situated at a given depth of one of the two substrates. The method includes a separation annealing step implemented in a furnace, wherein the annealing includes a first phase during which the temperature changes along an upgrade allowing a high temperature to be reached and annealing at this high temperature to be stabilized, and a second phase during which the temperature changes along a downgrade, at the end of which the furnace is opened to unload the substrates from the furnace. The second phase is regulated so as to minimize temperature inhomogeneities such as cleavage defects at the detached surfaces of the substrates when the furnace is opened. | 04-29-2010 |
20110195560 | METHOD OF PRODUCING A SILICON-ON-SAPPHIRE TYPE HETEROSTRUCTURE - The invention provides a method of producing a heterostructure of the silicon-on-sapphire type, comprising bonding an SOI substrate onto a sapphire substrate and thinning the SOI substrate, thinning being carried out by grinding followed by etching of the SOI substrate. In accordance with the method, grinding is carried out using a wheel with a grinding surface that comprises abrasive particles having a mean dimension of more than 6.7 μm; further, after grinding and before etching, the method comprises a step of post-grinding annealing of the heterostructure carried out at a temperature in the range of 150° C. to 170° C. | 08-11-2011 |
