Descripción del proyecto
Cerrar el circuito en el ciclo de vida de los plásticos reforzados con fibra de carbono
Debido a la amenaza cada vez mayor del cambio climático, los países de todo el mundo presentan iniciativas para disminuir sus efectos y luchar contra la contaminación. Ello incluye medidas para fomentar el reciclaje de los plásticos reforzados con fibra de carbono (CFRP, por sus siglas en inglés), un material de desecho. A pesar de que están fabricados con una gran cantidad de materiales reciclables, resulta difícil descomponer o reciclar los productos con CFRP. El proyecto d-CFRPs, financiado con fondos europeos, tiene como objetivo cambiar esta situación mediante el desarrollo de CFRP reciclados o discontinuados que se pueden reciclar incluso cuando han pasado por graves fracturas o fatigas. El objetivo de la nueva tecnología propuesta es cerrar el círculo del ciclo de vida de los CFRP, lo cual resulta esencial para el uso sostenible de las fibras de carbono.
Objetivo
This project aims to develop high-performance RECYCLED/discontinuous carbon fiber reinforced plastics (d-CFRPs) with tailored mechanical, fracture and fatigue properties using state-of-the-art nano-modification technology. Moreover, a significant side benefit of this research is a further development and validation of a fatigue test method for CFRPs towards standardization. The project involves: (1) formulate and characterize a series of epoxies modified by different nano-additives, i.e. rubber, silica, carbon nanotubes and graphene; (2) produce a series of d-CFPRs based on selected nano-modified epoxies and recycled carbon fibres; (3) characterize the mechanical properties, fracture toughness and fatigue resistance of the d-CFRPs; (4) investigate the fracture mechanisms and quantify the fracture features of d-CFRPs for both quasi-static and fatigue failure to build the correlation between fracture features and energy dissipation; (5) further develop and validate a fatigue test approach for CFRPs towards standardisation, together with other world-leading researchers from ESIS-TC4 (European Structural Integrity Society Technical Committee 4). Turning CFRP waste into a valuable resource and closing the loop in the CFRP life-cycle is vital for the sustainable use of carbon fibres. The research outcomes of this project (turning CFRP waste into high-performance d-CFRPs) will fit neatly with the big priority of Horizon 2020 Work Programme 2018-2020 in ‘Increased investment in sustainable development and climate related R&I’, and the new ‘From Waste to Resource (VANG)’ programme developed by Dutch government. The successful development of high-performance d-CFRPs will facilitate the recycling of CFRP waste and promote the applications of recycled d-CFRPs, hence to make contributions to ‘From Waste to Resource’. Moreover, the contribution to the development of a reliable standard for fatigue test of CFRPs will significantly benefit the research and industrial communities.
