Summary:Carbon fiber reinforced ABS (Acrylonitrile Butadiene Styrene) was produced via extrusion with varying fiber content and length. In this initial study, the challenges of processing this material were investigated along with the determination of rheological and thermal properties of the final composite. For material characterization, Fourrier-Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and capillary rheology techniques were used. Results showed correlation between the presence of process additives and carbon fiber content with composite properties, mainly in thermal stability and actual fiber content whereas rheological properties seemed largely unaffected. All mixtures were also submitted to mechanical testing and SEM (Scanning Electron Microscopy). Mechanical testing showed increases in tensile strength and modulus. Surface analysis showed poor interface between fibers and matrix as well as a random distribution of the reinforcement phase along the composite.
