Acrylonitrile-butadiene-styrene, Carbon Fiber, Sizing Layer, Fiber Reinforced Polymer Composites, Melt Mixing

In this thesis, short carbon fiber (CF) loaded acrylonitrile-butadiene-styrene (ABS) based composites were prepared. The four different loading ratio of CF as 5%, 10%, 15% and 20% were used and the optimum concentration was tried to obtain. Additionally, sizing layer of CF was removed and effect of the sizing to basic properties of composites was studied. Characterizations were based on mechanical, thermo-mechanical, melt-flow and morphological performances of composites.According to test results, properties of ABS were enhanced with CF additions. 10% and 15% loading ratios were obtained as optimum level for ABS/CF composites by the help of mechanical test results. Sized CF containing composites display better results than desized ones. MFI test showed that the processability of ABS did not affected by the inclusions of CF. As the SEM images of composites were examined, it was clearly observed that CF surfaces were covered by polymer matrix thanks to sizing layer of CF and debondings were formed for desized CF filled ABS composites.
