20090309264 | METHOD OF PRODUCING STIFFENED PANELS MADE OF A COMPOSITE AND PANELS THUS PRODUCED - A stiffened panel made of a composite includes a skin and at least one stiffener having a more or less closed volume. In order for the fibres of the composite to be held in place during fibre deposition and during pressure application while the resin of the composite is being cured, a moulding core is placed between the fibres at the position of the more or less closed volume of the stiffener. The moulding core includes a flexible bladder filled with a granular solid material, the thermal expansion coefficient of which is close to that of the composite used to produce the stiffened panel. The pressure in the bladder is increased before the composite is cured, so as to compensate for the forces applied for compressing these fibres during production of the panel. | 12-17-2009 |
20090309268 | METHOD FOR PRODUCING STRUCTURES OF COMPLEX SHAPES OF COMPOSITE MATERIALS - A method for producing a composite material part having a so-called non-strippable shape includes producing mold components, or cores, which are to be extracted from the part after the composite material has been cured. In a first step a core is produced from an elastomeric bladder the granular solid material and the bladder is depressurized. In a second step, after setting the core and the composite material the volume of the core is modified in a controlled manner for example by selecting the solid granular material based on its thermal expansion properties or by acting on the pressure in the bladder. | 12-17-2009 |
20100278586 | STRUCTURAL CONNECTING ROD MADE OF A COMPOSITE AND PROCESS FOR PRODUCING SUCH A CONNECTING ROD - A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process. | 11-04-2010 |
20110042863 | METHOD FOR MAKING A MOULDING CORE, AND MOULDING CORE FOR MAKING A COMPLEX PART MADE OF A COMPOSITE MATERIAL - In order to make a structure of a composite material including elongated hollow shapes, such as hollow shapes associated with stiffeners of a stiffened panel, the invention comprises making cores including a bladder made of an elastomer material. The invention relates to a method for making such extractable cores in order to obtain cores having a very important length, and allowing the use of said cores for the industrial production of composite parts. The bladder is a cylindrical bladder that is conformed in a core mould, wherein the core itself does not have to be cylindrical, before being filled with a granular material and submitted to a negative pressure in order to impart a stable shape to the core by compaction of the granular material. | 02-24-2011 |

20120132310 | COMPOSITE TUBULAR PARTS WITH COMPLEX SHAPES - A tubular part with a complex geometrical shape, the tubular part is made of a composite material including, on the one hand, a core part made of a very high-temperature resin obtained by a 3-D direct-creation method using a very high-temperature thermoplastic resin and, on the other hand, a coating of resin-impregnated fibres. The part includes, for example, at least one internal separation of the tube into several conduits that do not communicate with one another. The part is suitable for conveying air flows in opposite or separate directions. One of the conduits can be a dedicated cable raceway. | 05-31-2012 |

20150224674 | METHOD FOR PRODUCING THERMOSETTING COMPOSITE PARTS BY DRAPE FORMING OF PREIMPREGNATED MATERIAL - A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by drape forming of the prepreg material. The material laid-up in the form of tapes and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return the laid-up material to a temperature below the glass transition temperature of the prepreg state in question. | 08-13-2015 |
20150274912 | METHOD FOR PRODUCING PARTS MADE OF THERMOSETTING COMPOSITE BY LAYING OF FIBERS OF PREIMPREGNATED MATERIAL - A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by placement of fibers of the prepreg material. The material is laid-up in the form of rovings and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return to a temperature below the glass transition temperature of the prepreg state. The temperatures and the pressure are determined so that the part obtained has a void content of less than 4% by volume. | 10-01-2015 |
