Continuous carbon fibre-reinforced thermoplastic composites have convincing anisotropic properties, which can be used to strengthen structural components in a local, variable and efficient way. In this study, an additive manufacturing (AM) process is introduced to fabricate in situ consolidated continuous fibre-reinforced polycarbonate. Specimens with three different nozzle temperatures were in situ consolidated and tested in a three-point bending test. Computed tomography (CT) is used for a detailed analysis of the local material structure and resulting material porosity, thus the results can be put into context with process parameters. In addition, a highly curved test structure was fabricated that demonstrates the limits of the process and dependent fibre strand folding behaviours. These experimental investigations present the potential and the challenges of additive manufacturing-based in situ consolidated continuous fibre-reinforced polycarbonate.

The main objective of this article is to develop a high wear resistance carbon fibre (CF)-reinforced polyether ether ketone composite with the addition of multi-wall carbon nano-tubes (MWCNT). These compounds were well mixed in a Haake batch mixer and compounded polymers were fabricated into sheets of known thickness by compression moulding. Samples were tested for wear resistance with respect to different concentrations of fillers. Wear resistance of a composite with 20 wt% of CF increases when MWCNT was introduced. The worn surface features have been examined using a scanning electron microscope (SEM). Photomicrographs of the worn surfaces revealed higher wear resistance with the addition of carbon nanotubes. Also better interfacial adhesion between carbon and vinyl ester in a carbon-reinforced vinyl ester composite was observed.
