dc.description.abstractThis research project aimed to test the mechanical properties and the capability in wear resistance of ultra-high molecular weight polyethylene composite as well as determine the optimal formulation of UHMWPE-based composites which had a main component of aluminum oxide. The developed formula was used in the manufacture of run-flat wheels and thus applied to build run-flat wheels with an understanding of the proper molding conditions under the run-flat wheel forming process. Two materials used in the research consisted of super-high molecular weight polyethylene (UHMWPE) as the base material and the additive of aluminum oxide (Al2O3). The parameters employed in the hot compression process to obtain the specimen for the experiment consisted of compressive force, temperature, time, and the ratio between super-high molecular weight polyethylene and aluminum oxide. The test for mechanical properties consisted of an impact test, a hardness test according to the ASTM D2240 standard, a tensile test according to the ASTM D638 standard type I, and a wear test according to the ASTM G77 standard. The results indicated that a hot compression condition under a pressure of 5 MPa, a temperature of 210°C for 90 min, and using 5% Al2O3 HTM 30 material caused mixed uneven powder particle sizes between 2 to 5 µm. The tensile test results inferred the yield strength of 20.52 MPa, ultimate tensile strength at 29.96 MPa, breaking strength at 22.83 MPa, elongation at break at 265.8%, and modulus of elasticity at 784.46 MPa. The highest hardness was 62 shore D, the high impact strength was 586.8 J/m, and it was displayed for the wear rate of hot compression specimens made of UHMWPE mixed with 5% HTM-30. Moreover, it introduced a coefficient of friction, the wear rate, and the density of 0.12, 8.66E-11 mm3/N.m, and 1.2446958 g/cm3, respectively.en_US
