Abstract

Extrusion-based processes offer the possibility of producing carbon fibre reinforced composite (CFRC) components for lightweight construction of virtually any size and shape. However, many challenges still need to be addressed before their widespread adoption. Chief amongst them is the presence of defects and the material's anisotropic and heterogeneous internal structure. In this study, X-ray micro-computed tomography (micro-CT) has been utilised to analyse, characterise and compare two suites of five 3D printed short CF/PEEK samples and the two commercial feedstock materials used to produce them. Main material constituents (fibres, matrix, voids) have been identified and segmented, their distribution mapped and visualised in 3D and respective volume fractions quantified. Voids have been individually labelled and their key geometrical characteristics extracted and analysed. Similarly, preferential fibre orientation has been measured. Furthermore, the effect of key 3D printing parameters on samples' microstructure has been assessed.
