Mechanical properties of Copper Ferrite CuFe₂O₄‐ polymer composite fabricated using 3D printer
Abstract
The effect of speed of powder dispenser on the mechanical properties of ABS-CuFe₂O₄
composites was studied. The samples in the experiment were printed by 3D printer
which produce three dimensional objects from the digital file are built up layer by layer.
The amount of filler content added into each sample was controlled by the speed of
powder dispenser which is off, low, medium, and high. The properties of pure ABS and
composite ABS CuFe₂O₄ samples were investigated based on the distribution of fillers. Weight percentage (wt. %) of filler added into each sample was determined by using
thermogravimetric analysis (TGA) and the density of the composites were identified by
using density test. Tensile test and Vickers microhardness were carried out to determine
the effect of filler content on mechanical properties. The effect of filler on viscoelastic
behavior was assessed by using dynamic mechanical analysis (DMA). Addition of filler
content in ABS matrix slightly decreases the strength of composite from 17.1MPa to
14.64MPa. Besides, storage and loss modulus were decreases with the speed of powder
dispenser. The agglomeration of filler particle at high loading causes formation of
microvoids that lowering both mechanical and viscoelasticity of composite can be seen
on the surface morphology of the fracture surface with scanning electron microscope
(SEM).
