| Abstract: | The tribological properties of unsaturated polyester with a plain weave polyester fabric and poly(tetrafluoro-ethylene) fillers are evaluated in reciprocating sliding at 23 to 220°C. Thermogravimetric analysis and differential scanning calorimetry show that poly(tetrafluoro-ethylene) restricts the thermostability, while the curing reaction becomes more pronounced in the presence of poly(tetrafluoro-ethylene). The pure polyester composites show continuously increasing friction and overload above 120°C, while the poly(tetrafluoro-ethylene)-filled composites indicate a regime of increasing friction up to 100°C, decreasing friction at 100–160°C, and increasing friction above 160°C. The infrared spectra of worn composites have absorption bands representing poly(tetrafluoro-ethylene), curing, and degradation of the matrix. |
