Item Materiales compuestos para la optimización de celosías espaciales(2004-04) Mezzacasa, Ricardo; Forcat, Arturo; Isasi, Victor; COMPOSITESpace frames are widely employed in roof structures and in other construction and civil work applications and are generally formed in metal materials and, generally, steel. This employment of traditional materials presents some restrictions in terms of overloading and particularly with regards to rustproofing which limits the use of these systems in aggressive environments. In an attempt to overcome these problems, this article presents a space frame system which has been integrally developed on the basis of advanced materials in the Form of organic matrix composites. When compared with the long-standing experience of steel space frames which have been optimized over the years, these composite variations prove to be a valid alternative which are technically and economically viable for certain applications which need to be lightweight and rustproof as in the case of structures in and around marine environments, chemical plants, extensions to existing buildings, etc.Item Sintesi autopropagante ad alta temperatura in condizioni di microgravità(2003-07) Licheri, Roberta; Orrú, Roberto; Cao, Giacomo; De Wilde, Jimmy; Beloki, Inigo Agote; Jarvis, David John; Froyen, Ludo; EXTREMATSelf-propagating high temperature synthesis (SHS) under microgravity conditions was studied. The green density of the reacting sample also influenced SHS processes since it affected system reactivity and thermal conductivity of the compact. Either for the case of cylindrical pellets or during combustion front quenching (CFQ) experiments, temperature during reaction evolution was measured using thermocouples embedded in the pellet.
