| dc.description.abstract | Fused deposition modelling is a simple and affordable additive manufacturing technology utilising filament extrusion of polymeric materials to manufacture 3D products layer by layer. This work explored the feasibility of using fused deposition modelling to produce natural fibre reinforced elastomeric composite. Kenaf fibre and thermoplastic polyurethane (TPU) composite filament were prepared by using internal mixer for compounding and extruded to form filament for feed stock of 3D printing with different kenaf fibre loading (0-20wt%). The TPU filament with 0-10wt% of kenaf fibre were successfully extruded to fabricate test samples. The composites filament with 20wt% of kenaf fibre fracture prior to extrusion in 3D printing. The results showed that tensile strength, elongation at break, density and shear stress decreased, Young modulus, hardness, water absorption of printed samples increased with increasing kenaf fibre loading. Tolerance test showed shrinkage of printed products can be controlled with increasing of kenaf fibre. Next, in order to improve the matrix flexibility of the composite with higher fibre content for printing purposes, further assessment was carried out by blending TPU with different loading of epoxidized natural rubber (ENR) (10-30wt%). TPU/ENR blends were compounded with 10wt% and 20wt% kenaf fibre and their filament were successfully extruded. Results obtained shows that tensile strength, elongation at break, Young modulus and hardness of the printed samples decreased while water absorption and density of printed sample increased with increasing ENR loading. Tolerance test showed inclusion of ENR increase dimensional stability of printed sample. Shear stress showed the variation in trend with increasing ENR loading. As conclusion, with increasing Kenaf fibre and epoxidized natural rubber loading would affect the mechanical and physical properties of the printed samples. | en_US |
