Développement de structures composites intelligentes

Depuis quelques années le CETIM-CERMAT et le LPMT développent et élaborent un nouveau type de matériau actif, le M3C, matériau composite à comportement contrôlé. Le principe de ce matériau consiste à rendre une structure composite active sans rajout d'actionneurs ou d`éléments extérieurs. L'activation du matériau est réalisée grâce à une source interne de chaleur creé par effet Joule à l'aide de renforts actifs. L'objectif de cette présentation consiste, dans un premier temps, à faire une présentation complète de ce nouveau matériau, et à situer ses performances par rapport à celles des autres matériaux intelligents, ceci en terme de domaine d'application, de puissance utile, de rendement, de temps de réponse. Dans un second temps, nous présenterons les différents outils numériques qui ont été développés afin de permettre le calcul et l'optimisation de ce matériau. Nous finirons cet article par une application potentielle du M3C

Integrated Product Service Engineering - Factors influencing environmental performance

This paper aims to lead theoretical discussion regarding which IPSE (Integrated Product Service System) factors are expected to increase environmental performance of a life cycle compared to a traditional product sales business. Existing theories such as theory of product development, transaction cost theory and theory for risk management are used and the paper theoretically analyzes and identifies the following crucial characteristics; complexity of the product, uncertainty of offering, control of product operation, asymmetric information and scale of economy

Product Design Considerations for Improved Integrated Product/Service Offerings

"The efficient utilization of energy, sustainable use of natural resources, and large-scale adoption of sustainable technologies is the key to a sustainable future. The Handbook of Sustainable Engineering provides tools that will help us achieve these goals". Nobel Prize Winner Dr. R.K. Pauchauri, Chairman, UN Intergovernmental Panel on Climate Change As global society confronts the challenges of diminishing resources, ecological degradation, and climate change, engineers play a crucial role designing and building technologies and products that fulfil our needs for utility and sustainability. The Handbook of Sustainable Engineering equips readers with the context and the best practices derived from both academic research and practical examples of successful implementations of sustainable technical solutions. The handbook's content revolves around the two themes, new ways of thinking and new business models, including sustainable production, products, service systems and consumption while addressing key assets based on new materials, optimized resource management, and new energy sources. Contributions reflect a focus on state-of-the art insights into employing smart materials, recycling e-waste, water utilization, solar cells, product lifecycles, transportation and reverse manufacturing. Supportive of this, underlying issues such as engineering education, consumer behaviour and the regulatory climate complete the handbook's comprehensive treatment of the problems and most promising solutions
