End of life regulations, material consumption reductions or restrictions, ask engineers about their potential use. Innovative recycling solutions arise that recover efficiently carbon fibres. This paper explores the design for composites recycling issue. Recycler becomes a new knowledge expert for the designer. It is necessary to analyze their information shares and exchanges. The recycler is an end of life facilitator. He is also the second life material user and can ask for material evolutions. The collaboration must be improved using knowledge performance indicators. These discussions will be enlightened by examples from carbon recycling experiments.

However, end-of-life solutions for these materials are still under development. In this chapter, a solution linking design strategies with a recycling process based on the solvolysis of the matrix by water under supercritical conditions is proposed. The needs and multi-disciplinary skills required for (i) taking recycling possibilities into account from the early stages of the product design, and (ii) the necessity to standardize its recycling capabilities with design requirements, will both be discussed. The present chapter highlights the need for designers to take a functional approach into consideration, including material characterization, limits of the recycling process, constraints and opportunities. The first lessons learned from experiments using this technique will be shown.

En conséquence, les industriels doivent dorénavant considérer la satisfaction d’un besoin par la proposition d’un couple produit et service (PSS). Le traitement simultané de ces deux enjeux permettra d'améliorer la position dans la chaîne de valeur, d’accroître la valeur ajoutée de l’offre et d'améliorer le potentiel d'innovation de l’entreprise productrice de la solution PSS. Le challenge se situe donc dans l’optimisation du ratio valeur d’usage/prix de l’offre PSS pour le client et également pour l’industriel. Nous proposons dans cette contribution les prémices d’un modèle d’analyse de la valeur de l’innovation des systèmes de produits et services. Nous avons pour cela identifié les fonctions attendues d’un PSS pour le client et celles attendues par le fournisseur de la solution. Ces fonctions rapportées au coût global du système permettent de déterminer la valeur de l’offre pour les protagonistes et d’aider à la décision du développement effectif de l’offre. Abstract - The traditional economy based on selling products to clients is currently challenged by the growing user interest for the product use value than the product exchange value. Consequences for manufacturers are significant because they must now extend their skills to the fulfillment of a need through the delivery of an integrated set of products and services (PSS). The added service will improve the position in the value chain of the product, increase the added value of the offer and improve the innovation potential. These benefits of the PSS can be obtained considering the global design collaboration and the engineering work necessary to design and deliver PSS. The challenge therefore lies in optimizing the ratio value of use to cost of the PSS for the user as well as for the industry. We propose in this article the foundation of a model for analyzing the value of a PSS innovation. The model is built upon the list of function expected by the user and those expected by the provider of the system. Each list related to the system whole costs will give an idea of the value of the offer for each stakeholder and aggregating the value an aid to decide whether the development is to be launched or not.

Moreover, life-cycle cost can be influenced up to 70% by decisions taken during the conceptual design phases. The need for reliable multi-criteria decision aiding methods is thus greater in these phases. Various multi-criteria decision aiding methods are proposed and used in the literature. The main criticism of these methods is that they usually produce contradictory results for the same problem. In this work, seven widely used multi-criteria decision aiding methods (weighed sum, weighted product, Kim and Lin, compromise programming, TOPSIS, quadratic mean and ELECTRE I) are analysed. This analysis was based on a real industrial case to develop a solar collector. The proposed multi-criteria decision aiding methods were compared in terms of three criteria deemed relevant in the relevant context: (1) adaptation of the type of results the multi-criteria decision aiding method is expected to bring, (2) correct handling of input information and (3) adaptation of the degree of compensation. Based on these criteria, it was proven that weighted product is the most appropriate multi-criteria decision aiding method in our case. In addition, it has been demonstrated that sensitivity analysis can improve the benefit of using the multi-criteria decision aiding method chosen when dealing with imprecise information due to immaturity of concepts.

POMPIDOU, Stéphane; PRINCAUD, Marion; LERAY, Dimitri; PERRY, Nicolas In order to decrease both energy consumption and CO 2 emissions, the automotive, aeronautics and aerospace industries aim at making lighter vehicles. To achieve this, composite materials provide good opportunities, ensuring high material properties and free definition of geometry. As an example, for cold applications, the use of carbon fiber/thermoset composites is ever increasing, in spite of a high fiber price. But in a global and eco-friendly approach, the major limitation for their use remains their potential recyclability. Recycling a composite means having a recycling technology available, getting a dismantle solution and an access for the product, and disposing identification plus selection possibilities to the materials. Thus, carbon fibers recovery (i.e. recycling and re-processing) would both help design engineers to balance energy efficiency and cost, and open new opportunities for developing second-life composites, dedicated to the manufacture of medium or low loaded parts (non-structural in many cases). A first section presents an overview of composite recycling possibilities. Indeed, environmentally and economically, composite incineration is not attractive (even with an energetic valorization), let-alone burying. Reuse and recycling thus remain the two most interesting options. Aeronautics offers a high potential in terms of fiber deposit. In southwest France, composites recycling will increase in terms of quantity due to dismantling platforms TARMAC (dedicated to civil aircraft applications) and P2P (for the disassembly of ballistic weapons). In addition, from a technical point of view, and even if end-of-life solutions for composites still remain under development, solvolysis (i.e. water under supercritical conditions) already offers the opportunity to recover carbon fibers. The resulting recyclate retains up to 90 percent of the fiber’s mechanical properties. A second part will explore the recycling to design issue (i.e. how recycling processes have to balance the previous aspects of the end-of-life proposal). The recycler clearly becomes a new supplier in the carbon fiber lifecycle, by revalorizing wastes with alternatives to burning. Moreover, increasing carbon fiber shelf life reduces its product life impact. Finally, promoting carbon fiber end-of-life would ensure to link aeronautics, automotive, and leisure and sports industries; but one can create demand for recycled reinforcement, by packaging it in useful and attractive forms for those end-users (e.g. pseudo-continuous fiber, felt, strips, bands, patches, etc.). These sections will be enlightened by several examples from collaborations between I2M and local industries.

With today's new environmental standards, the choices of materials must also be compatible with the aims of ecodesign. We promote wood based boats, and replacing exotic woods with local varieties (from France). An environmental impact assessment is needed to clarify the relative position of each solution. Methods: In order to validate the choices, we used a Life Cycle Assessment (LCA) "from cradle to grave" of the hull. This LCA is based on the comparison of the different materials used: aluminum, composite, exotic wood and maritime pine. This study is based on the construction of an 18-meter-long passenger transport boat. These evaluations were carried out with respect to ISO 14040 standards, beginning with an existing database and measurements taken on the building and production sites. Results: Our results demonstrate the benefits of using a wood-based hull compared to other materials. Moreover, the results show that the maritime pine used in replacement of imported exotic woods is more favorable from both economic and environmental points of view. This LCA allowed us to characterize precisely the stages in the life cycle of a passenger boat and to propose a hierarchy between the different materials under comparison for the purposes of boat building. The recommendations and lines of progress highlighted by this study will allow us to enhance the efficiency of upcoming constructions and to promote the ecodesign conception in the boatyard. The authors extend their warmest thanks to the Cluster ABOVE who financed the research and in particular to the Dubourdieu 1800 boatyard (Mr Emmanuel Martin) who built the Greenboat and who supplied us with a great quantity of data for our LCA.
