Analisa Karakteristik Hybrid Komposit Polypropylene diperkuat Titanium Carbide dan Serat Ampas Tebu untuk Aplikasi Material Impeller Turbin Vortex

Abstract

The use of polypropylene polymer composite materials reinforced with sugarcane bagasse fibers has been extensively studied due to its lightweight density, increased strength, and corrosion resistance, making it suitable for applications by adding titanium carbide (TiC) as a nano-sized reinforcement and analyze the polypropylene (76%, 83%, 90%), titanium carbide (5%, 7%, 9%), and sugarcane bagasse fibers (5%, 10%, 15%). Titanium carbide (TiC) and sugarcane bagasse fibers were processed using the mechanical alloying method. Homogenization of polypropylene, titanium carbide (TiC), and sugarcane bagasse fibers was performed using the reflux method at a temperature of 170ᵒC with a stirrer speed of 500 rpm. the mechanical characterization result of the hybrid composite shows the most negligible density of 0.801 g/cm3, the highest tensile strength of 32.898 MPa, the highest bending strength of 58.481 MPa, the highest impact strength of 31.1 kJ/m2, and the highest elasticity of 2101.905 MPa. Morphological observations to asses and identify the interface bonding of the specimens were conducted using Scanning Electron Microscopy (SEM) with magnifications of ×500, ×1000, ×3000, and ×5000, while the matrix and filler elemental composition mapping was identified using Energy Dispersive Spectroscopy (EDS). Crystal structure analysis using X-ray Diffraction revealed the highest degree from the largest at 29.98 nm to the smallest at 5.02 nm. Numerical simulation result showed low deformation, low equivalent elastic strain, and low equivalent stress in the impeller with five blades.
