PILOTS STRATEGY 2
Long fiber and matrix demanufacturing, textile reprocessing and re-use.
Input material will be mainly related to Glass Fiber Reinforced Plastics scraps and waste from wind energy sector. High efficiency pyrolysis will be used to obtain long fibers clean and with a minimal decrease of mechanical performances. Innovative re-sizing and textile reprocessing of the recovered carbon fibers will lead to a variety of textile products like continuous roving or mats that will allow the realization of products for aerospace sector and markets with a high demand of cheaper Carbon Fibers (as automotive).
Strategic importance of the pilot
Carbon fibers reclaimed by different routes exhibit different retention rates of mechanical properties with respect to virgin fibres. Pyrolysis may reach a retention of strength of 98-99%. However, the energy consumed is 2.6 times higher than mechanical methods and it needs a significant process optimization. As a whole, the pyrolysis process is acknowledged as the most viable and sustainable CFRP recycling process to achieve process and resource efficiency.
A challenge is represented by the optimization of the textile reprocessing technologies, aimed at obtaining continuous yarns from recovered discontinuous fibers, which is a key-aspect in DeremCo project.
The availability of rCF with high retention of mechanical properties and competitive costs can unlock the potential as secondary material. For example, the automotive market is driven by cost reduction strategies encompassing reduction of cycle time and material cost.
According to this the 5 Demo-cases are:
- Injection molding of bathtubs for the production of automotive pump bracket
- Injection molding of wind turbines for the production of shipbuilding boat battery cover
- Hybrid yarn spinning and weaving of windturbines for the production of technical yarns and fabrics
- Injection molding of aeronautic and wind turbines for the production of automotive components
- Rolling of wind turbine for constructions
