Revista Internacional de Métodos Numéricos para Cálculo y Diseño en Ingeniería

Abstract

International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.

Desde 1985 la Revista Internacional de Métodos Numéricos para Cálculo y Diseño en Ingeniería (RIMNI) contribuye a la difusión en castellano, portugués e inglés de los desarrollos teóricos y aplicaciones prácticas de los métodos numéricos, tanto en relación con su utilidad como instrumentos de cálculo y análisis para el ingeniero y el científico, como en aspectos que inciden en las nuevas tecnologías de diseño y proyecto de producción y procesos en ingeniería. La revista abarca áreas diversas, tales como: modelos matemáticos y numéricos de problemas de ingeniería, desarrollo y aplicaciones de los métodos numéricos, nuevos avances en temas de software, innovaciones en el campo del diseño por computador, aspectos didácticos de los métodos numéricos, etc. La revista constituye una fuente de información imprescindible para ingenieros y científicos sobre innumerables temas relacionados con los métodos numéricos y sus aplicaciones, contribuyendo a promover la transferencia de conocimiento interdisciplinar y, por consiguiente, a acortar la distancia que existe entre los desarrollos teóricos y las aplicaciones concretas.

PLATFORM: Study of the integration of materials manufactured with CNTs in current processes of manufacture by infusion in aeronautics

Abstract

The need to improve non-intrinsic properties of composite materials is a fact that leads to studies such as the one carried out in this project, where the possibility of integrating new materials development into common materials is analyzed to provide them with an improved properties: mechanical or electric.

The main objective of the project is to analyze the possibility of introducing the new materials into the current manufacturing processes, improving the properties of the raw material (dry carbon fiber fabric infused with monocomponent epoxy resin), under aeronautical requirements.

Two material developments are made with carbon nanotubes in two different formats: buckypapers and thermoplastic doped veils.

The implementation of each materials has been studied in current infusion processes, more concretely manufacturing processes by RTM (Resin Transfer Molding). The studied possibilities are: buckypapers incorporated in dry preforms, for their subsequent infusion and doped veils embedded in dry preforms, for their subsequent infusion.

The obtained results at this moment (2nd year of the project) are satisfactory, although it´s necessary to optimize the materials to improve the automation of the manufacturing process and achieve a greater improvement of properties.

PLATFORM: Study of the integration of new nanomaterials in a current processes of manufacture with prepreg materials in aeronautics

Abstract

PLATFORM appear for the need to improve non-intrinsic properties of composite materials, principally its mechanical and electrical properties. The main objective of the project is to analyze the possibility of introducing three new materials in development into the current manufacturing processes, improving the properties of the raw material, more concrectly prepreg unidirectional carbon fibre with epoxy resin. Several material developments are made with carbon nanotubes in three different formats: buckypapers, thermoplastic doped veils and CTN treated prepreg. The implementation of each materials has been studied in current infusion processes, more concretely manufacturing with prepregs and cure in an autoclave. The studied possibilities are: buckypapers incorporated and doped veils embedded in prepreg laminates or full manufacturing with treated prepreg. The obtained results at the 2nd year of the project are satisfactory, but it´s necessary to optimize the materials to automate the manufacturing and improve the final properties.
