Mechanical properties and 3D printability of fabricated natural fiber reinforced polylactic acid composites
The study aims at the control of the process parameters specifically the layer thickness, print orientation, raster angle, raster width and air gap to enhance the part building methodology on the 3D printing, fused deposition modelling (FDM) process, by improving the mechanical properties such as the tensile, compression, flexural, impact strength, sliding wear and the surface smoothness. The responses will be studied and validated using appropriate stastical models, microphotographs and non-traditional optimization.
Central Composite Design (CCD) is the process improvement strategy which will be employed to minimize the surface smoothness of the 3D printed object. Empirical models will be developed to relate the experimental response and the process input parameters. The validity of the models will be justified by the ANOVA and residual analysis technique.
The study of the sliding wear of the sample will also be carried out to improve the resistance to wear of the object. To determine the complex dependencies of wear, a statically validated model will be designed which will facilitate the prediction of the wear of the 3D printed object.
