Conférence invitéeAHMADI-SENICHAULT, Azita; VIGNOLES, Gérard; BRESSON, Grégory; CATY, Olivier; AYVAZYAN, Viguen; GREGORI, Maria Luisa; COSTA, S.F. (2014)Aeronautical and space vehicles include many parts made of composite materials. The thermal design of these materials is critical versus their application. Indeed, the presence of very high thermal gradients during use may ...

Communication avec acteBRESSON, Grégory; CATY, Olivier; MERZEAU, Jonathan; DAU, Frédéric; AHMADI-SENICHAULT, Azita; VIGNOLES, Gérard (Association Française de Mécanique, 2013)Silica/phenolic composites are used in atmospheric re-entry heat shield parts in spatial and strategic domains. For this application, the material is submitted to thermo-mechanical stresses that lead to delaminations. To ...

Communication avec acteVIGNOLES, Gérard; BRESSON, Grégory; LORRETTE, Christophe; AHMADI-SENICHAULT, Azita (Journal of Physics Conference Series, 2012)We propose a lightweight method for the determination of heat diffusivity of silica fiber bundles based on the use of a laser and an IR camera. The fiber bundle is maintained in traction in a holder; exposition is made as ...
