A bioinspired interphase for improved carbon-fibre composite performance

This work focused on the surface properties of carbon-fibres and the effects of different surface treatments on the adhesion behaviour between fibres and matrix. An alternative approach to the current production process of carbon-fibres is presented which uses a dry plasma treatment to achieve comparable results in regards to fibre-matrix adhesion. Preliminary studies focused on single layer plasma films with controllable mechanical properties to form an interphase between fibres and matrix that combines high strength and energy absorption/damping capabilities. This would increase the service life of carbon-fibre composites by preventing micro-cracks between fibres and matrix.
