Abstract

Carbon-based materials have been attaining a great interest from researchers due to its versatility. This study intended to assess the potential of carbon fibre and its composite for bone replacement. The morphological, electrical conductivity and nanomechanical properties (modulus and adhesion energy) of locally obtained carbon fibre were assessed via microscopic devices of scanning electron microscope (SEM) and an atomic force microscopy (AFM), respectively. The carbon fibre was compounded with polyamide 6 and injection moulded prior to assessment of its tensile and morphological properties. The electrical conductivity of the carbon fibre was in a range of 0–1 mA. Whereas the mean modulus and adhesion energy were 1.96 GPa and 22.97 fJ, respectively. The tensile strength and modulus of the composite increased by 14.7% and 13.7% as compared to unfilled polyamide 6. With potential cells stimulating capability owing to its electrically conductive and excellent mechanical properties, carbon fibre could be hypothetically used with selected matrix for replacement of bone in non-load bearing areas such as craniofacial part.
