Mechanical and microstructural characterization of rubber particle reinforced thermoplastic for automobile bumper application
Thermoplastic elastomer composite produced from low-densitypolyethylene (LD-PE) mixed with 150μm pulverised rubber particles in variedproportions (5%, 10%, 15%, 20% and 25%) using stir casting technique wascharacterized for mechanical properties in relation to the base polyethylene.Tensile, impact,...

| Summary: | Thermoplastic elastomer composite produced from low-densitypolyethylene (LD-PE) mixed with 150μm pulverised rubber particles in variedproportions (5%, 10%, 15%, 20% and 25%) using stir casting technique wascharacterized for mechanical properties in relation to the base polyethylene.Tensile, impact, flexural, and hardness tests were conducted to investigate themechanical properties of the elastomer. The results obtained showed that thereinforcement with up to 20%wt of pulverised rubber particle generated acomposite with a higher modulus of elasticity of 374MPa and hardness of14.06BHN relative to those of the base material which are 227MPa and 11.48BHNrespectively. However, the bending strength and the impact energy of thegenerated composite are 40MPa and 19.5J, which are lower than those of the basematerial, which are 57MPa and 20J. This may be due to insufficient adhesionbetween the phases of the matrix and reinforcement. |
