Abstract Scope |
This study investigates the effect of porosity due to 3D printing on the mechanical performance of natural carbon-enhanced polymer composite (NCPC) materials. High-density polyethylene (HDPE) was compounded with natural carbons at various weight loadings (15-70 wt. %) which allowed for the creation of 3D printable filament that is compatible with commercially available fused deposition modeling (FDM) printers. Computed Tomography (CT) scans were obtained for the NCPC 3D printed structures to determine the percent porosity for each weight loading. Additionally, CT scans were used in the generation of a mesh to be input into the finite element analysis (FEA) software, ABAQUS, to simulate the deformation response due to porosity of the NCPC printed structure under tensile loading. The model was compared directly to a solid model which was validated through experimental testing. The comparison of porous to solid model yielded a noticeable loss of strength relative to the increase in porosity. |
