Description du projet
Ingrédients durables pour les structures composites légères
Le projet SUSPENS, financé par l’UE, mettra au point des résines époxy et polyester biosourcées à hauteur de plus de 95 %, présentant de nouvelles formulations qui assureront des performances élevées dans un cycle court. Ces résines seront combinées à des renforts durables fabriqués à partir de fibres naturelles et recyclées pour créer des composants sandwich. Des solutions de recyclage seront également mises au point. Un processus de pyrolyse innovant utilisera le flux de déchets émis par le processus de transformation des fibres de carbone pour optimiser la consommation d’énergie. Un processus de solvolyse spécial permettra de récupérer les résines biosourcées. Cette approche sera démontrée dans le cadre de la fabrication et de la récupération d’un bloc batterie de voiture, d’un pont et d’une coque de bateau de plaisance et d’une ailettes d’aéronef. Une analyse globale du cycle de vie viendra étayer cette démonstration en mesurant son potentiel d’atténuation de l’incidence environnementale sur le cycle du berceau au berceau.
Objectif
SUSPENS will develop a holistic approach, from bio-sourced and recycled materials to faster and lesser energy demanding processes, to produce sustainable composite structural parts, ensuring their manufacturability from the design conceptualization. This ambition is basically achieved by the R&D of the coupling bio/circular-materials and processes. SUSPENS will develop up to 95% bio-sourced thermoset resins, with formulations allowing fast cured manufacturing processes and properties adapted to high performance lightweight composite applications. To produce the parts, these resins will be combined with sustainable continuous reinforcing fibre such as natural based cellulose fibres, lignin-based CF, recycled CF staple yarn and continuous GF made from recycled GF for producing well engineered sandwich and hollow parts for transport industries. Some of these parts will be functionalised for added value and reduced assembling times. SUSPENS will also develop an innovative approach for sustainable, optimized energy reduced pyrolysis, using waste stream from the carbonization of precursors, reducing environmental impact of carbon fibre production. For the bio-epoxy, a specific solvolysis will be developed to separate the matrix from the fibres. SUSPENS will assess the valorisation of oil and organic components in these two recycling approaches to transform them into by-products. LCA and LCC studies will show that SUSPENS approaches, combining sustainable materials and processes, can reduce the CO2eq emissions at expected levels of about 40-50%. These achievements will be validated by producing three demonstrators with their respective business models: (1) automotive battery pack for electric vehicle, (2) sailing boat hull/deck and (3) aero-structure winglet part. SUSPENS results will pay-back in terms of lesser energy consumption and environmentally friendly products that can be recycled and expects to bring its assets to the market end of 2028.
