The main goal of this study is to analyze the effect of increasing the amount of titanium dioxide (TiO2) particle filler in polyetherimide (PEI) thermoplastic composite materials, which are widely used in automotive and aircraft components. TiO2 generally improves the stiffness of the materials but reduces their erosion resistance, and filler concentration beyond 10 % impairs the bending strength. In the present study, variation of the bending, thermal, and solid-particle erosive wear properties of TiO2-reinforced PEI thermoplastic composites were investigated by changing the amount of TiO2 filler. The results confirmed that higher filler concentrations improved the bending strength of the composite structure, but decreased their erosion resistance. It was also found that the bending properties of the thermoplastic composite samples eroded at a 90 degree impingement angle remained nearly equal to those of the uneroded samples, whereas they were significantly reduced at a 30 degree impingement angle. We also determined the thermal stability of the composites using thermogravimetric analysis (TGA) methods.
