Mechanical Characterization of Carbon Fibres Recycled by Steam Thermolysis: A Statistical Approach
Abstract : The recent development of technologies for recycling carbon fibre reinforced plastics (CFRPs) leads to the need to evaluate the
mechanical response of recycled carbon fibres. As these fibres are likely to be degraded during the recycling treatment, it is very
important to determine their tensile residual properties so as to evaluate their ability as reinforcement for new composite
materials. Carbon fibres reclaimed by a steam-thermal treatment applied to degrade the epoxy resin matrix of a CFRP are here
analysed. Two conditions were chosen so as to reach two degradation efficiency levels of the steam thermolysis. Several carbon
fibre samples were selected for mechanical testing carried out either on single filaments using single fibre tensile tests or on fibre
tows using bundle tensile tests. It is shown that the single fibre tensile test leads to a wide variability of statistical parameters
derived from the analysis. Bundle tensile tests results were able to indicate that fibre strength of recycled carbon fibre is similar to
corresponding as-received carbon fibres thanks to a statistically relevant database. Wide number of tested filaments enabled
indeed to obtain low scatters.
