N2 - High strength carbon fibre was recycled from aerospace epoxy composite scrap using a pyrolysis process. The feasibility of using the recycled fibre in a non-woven form for a flame-retardant epoxy was investigated. Single fibre tensile tests and SEM analysis were used to determine the quality of the recycled fibre. No significant change in the tensile properties of the fibre was seen and the fibres generally had a clean surface. The recycled fibre was converted into a non-woven mat using a wet process. The mat was then compression moulded with resin film into a plaque to give fibre volume fractions ranging from 20 to 40%. The mechanical performance of the plaques was then analysed. A positive linear relation between stiffness and fibre volume content was observed. However, the contribution to composite strength with increasing fibre volume content was less significant due to the degradation in fibre length during the high-pressure compression moulding process.
