| Resource Title | Muscovite and wollastonite as reinforcement to acrylonitrile butadiene styrene in fused deposition modelling |
| Date Issued | June 2020 |
| Abstract | Muscovite and wollastonite were used as reinforcement to 3D-printed acrylonitrile butadiene styrene (ABS) via fused deposition modelling (FDM). The effects of these fillers to the mechanical and thermal properties of ABS were investigated. Both fillers were loaded at 1, 3, and 5 wt%. The composites were characterized via scanning electron microscopy (SEM), tensile test, shore D hardness, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). ABS/muscovite composites exhibit maximum increase in tensile strength and elastic modulus of 83.6% and 76.6%, respectively at 3 wt% loading. ABS/wollastonite composites exhibit maximum increase in tensile strength and elastic modulus of 46.6% and 56.2%, respectively at 5 wt% loading. Both ABS/muscovite and ABS/wollastonite composites display no significant changes in maximum elongation. The tensile properties of the composites suggest that the addition of both fillers result to stronger and stiffer FDM 3D-printed structures without significant reduction in ductility. In terms of shore D hardness, only ABS/wollastonite composites exhibit significant increase due to the inherent hardness of the filler. Both ABS/muscovite and ABS/wollastonite composites show an increase in glass transition temperature of ABS corresponding to a reduced susceptibility to warping. The degradation temperatures of ABS composites slightly shifted to high magnitude, suggesting an improved thermal stability of ABS with the addition of muscovite and wollastonite. In conclusion, the incorporation of muscovite and wollastonite improves the mechanical and thermal properties of FDM 3D-printed ABS. |
