The COMPACRYL.2 (FUI) project aims to replace the thermosetting composite materials currently used in many applications by thermoplastic composite materials based on acrylic resin. In fact, these new materials make it possible to preserve the mechanical properties while leading to a gain in terms of HSE, economic, environmental and aspect properties. The COMPACRYL.2 project has demonstrated the relevance of its developments for ski and public equipment applications, with a short industrialization time and a medium-term aim.
The challenges of COMPACRYL.2 are of four types: societal (health of the workers, conservation of a French manufacture for skis and development of the activity for public facilities), environmental (use of monomers better meeting the criteria HSE, recycled and use of natural fibers), safety (creation of public equipments meeting future safety standards: breaking poles during shocks) and techniques (new resins, adaptation of reinforcements, adaptation of the implementation processes).
DISP's contribution focused on life-cycle analysis of current and new products. A set of sustainable indicators has been proposed with 8 impact categories. A multi-criteria model has been developed and tested to evaluate the environmental gains associated with new materials or new manufacturing processes.
A study of the impact of standardization in LCA studies was also carried out and gave rise to a scientific communication in an international conference of which an extended version was published in an international journal ('Normalization in Life Cycle Assessment: Consequences of new European factors on decision making ').
