Device for making a part of a composite material by resin-transfert moulding
The invention relates to a device (IO) for ma.king a part of a composite material by resin-transfer moulding, that includes a manufacturing mould (IO) in which is placed a blank (1) of the part to be impregnated with resin, characterised in that the manufacturing mould (20) is divided into a matrix (21) and one or more mobile structural members (22) to be indexed on the matrix (21), the whole defining, after assembly, an imprint corresponding to the shape of the part to be manufactured.FUI 072906222 projet CAPSAIRT
Procédés de fabrication en matériaux composites de pièces tridimensionnelles et/ou massives
L'invention concerne un procédé pour fabriquer en matériau composite une pièce brute ayant une forme massive et/ou tridimensionnelle, comprenant les étapes de : - bobiner à chaud au moins un toron de fibres renforçantes (24) imprégné de résine thermoplastique en quantité excédentaire, sur des reliefs de bobinage (17-23 ) d'un outillage de bobinage (16), pour constituer une préforme de la pièce fabriquée ; - matricer à chaud la préforme pour lui donner une forme souhaitée tout en évacuant la résine excédentaire ; - refroidir l'ensemble en maintenant sous pression l'outillage de matriçage (31) pour constituer la pièce brute. L'invention s'applique à la fabrication de pièces mécaniques structurelles telles que des pièces structurelles aéronautiques

A methodology for sharing experiences in incident management
International audienceThis article presents a methodology for the representation and sharing of experience gained during the management of incident and crisis situations. This methodology, which was initially developed for transportation accidents, is founded on the association of engineering and social sciences for the consideration of technical, human and organisational aspects of incident and crisis management. Based on interviews of people who have participated in the management of the situation at different hierarchical levels, this method formalises the development of the accident as a series of decision cycles: the particles of experience. The case study that is presented in this article occurred in a chemical plant, during the loading of a reactor with a dangerous chemical product. This accident caused no casualties but its management has induced an interesting experience in the management of incidents which could produce harmful consequences
