20110309547 | DEVICE FOR MAKING A PART OF A COMPOSITE MATERIAL BY RESIN-TRANSFER MOULDING - The invention relates to a device ( | 12-22-2011 |
20130069281 | DEVICE FOR MANUFACTURING A COMPOSITE PART BY RESIN INJECTION MOULDING - A device for manufacturing a part in composite material by resin transfer moulding and method is provided according to the present disclosure. The device includes a manufacturing mould in which at least one preform is intended to be arranged of the part intended to be impregnated with resin during a resin transfer process. The mould is subdivided into a die and at least one movable structural element intended to be indexed on the die to form an assembly, the assembly forming a cavity corresponding to a shape of the part to be manufactured. The mould is associated with at least one positioning frame having a low coefficient of thermal expansion in at least one dimension, the positioning frame being designed to allow the indexing and holding in position of the at least one movable structural element, corresponding to at least one singularity, on the die. | 03-21-2013 |
20130079434 | PROCESS FOR MANUFACTURING A PART MADE OF A COMPOSITE HAVING A HOLLOW CORE - A method for manufacturing a part in composite material with a hollow core is provided that includes applying at least one adhesive layer on an open surface of the hollow core. The adhesive layer is a blocking polymerizable adhesive layer having, after polymerization, sealing properties relatively to a resin and capable of preventing its diffusion towards an inside of the hollow core. Subsequently, the blocking adhesive layer is polymerized so as to achieve sealing of the hollow core. Additionally, various parts manufactured according to the methods of the present disclosure are also provided. | 03-28-2013 |
20130087955 | DEVICE FOR MANUFACTURING A CASING MADE OF A COMPOSITE MATERIAL AND MANUFACTURING METHOD USING SUCH A DEVICE - A device for manufacturing a fan casing of a turbomachine made of composite material, in which a mold includes a cylindrical body of lengthways axis and side flanges, and in which a counter-mold includes a cylindrical body and side counter-flanges. The counter-flanges are configured to be attached securely to the flanges, the body of the mold and the body of the counter-mold are concentric, the preform is configured to be positioned between the body of the mold and the body of the counter-mold, and the material of the body of the mold has an appreciably higher expansion coefficient than that of the body of the counter-mold. | 04-11-2013 |

20140083548 | LIQUID SUCTION DEVICE COMPRISING A TIP REDUCING THE FORMATION OF A SUCTION VORTEX - A device for suctioning a liquid contained in a vessel, that includes a take-up tube that is received in the vessel such that a bottom end of the section is submerged in the liquid. The bottom end of the take-up tube is extended downward by a rotationally symmetrical tip which has a main substantially vertical axis open downward and which includes an outer radial collar. | 03-27-2014 |
20140262046 | IMPREGNATION MANDREL WITH VACUUM LINER FOR MAKING A GAS TURBINE CASING MADE OF COMPOSITE MATERIAL - An impregnation mandrel for production of a gas turbine casing made from composite material, including: a mandrel having a central wall and two side plates; compaction bars, each including (i) a wedge configured to bear against a fibrous reinforcing part covering angles formed between the central wall and the side plates of the mandrel, and (ii) an attachment flange configured to be attached to the corresponding side plate of the mandrel; a flexible casing forming a vacuum bag and configured to be applied at least against the fibrous reinforcing part covering the central wall of the mandrel; and a mechanism for injecting resin into a space defined between the vacuum bag and the mandrel at one of longitudinal ends of the fibrous reinforcement and for extracting the resin at the opposite end. | 09-18-2014 |
