Abstract
In this investigation, the tribological and mechanical performance of 10 wt.-% filled nano and micro epoxy composites were studied and compared. Nano fillers are Al2O3, TiO2 and clay and micro fillers are Al2O3, TiO2 and fly ash. Mechanical and wear tests were carried out. Wear tests were performed on pin-on-disc arrangement. Test conditions were 5, 10, 15 N applied load values, sliding speed of 0.8 m × s−1, 2000 m sliding distance under dry atmospheric conditions. The results show that the mechanical and tribological performance of micro filler filled epoxy composites are better than those of the nano filler filled composites.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Untersuchung wurde das tribologische und das mechanische Verhalten von Epoxy-Kompositen ermittelt und verglichen, die 10 wt.-% Nano- bzw. Mikro-Füller enthielten. Als Nano-Füller wurden Al2O3, TiO2 sowie Ton und Flugasche verwendet. Es wurden mechanische Tests und Verschleißversuche durchgeführt. Die Verschleißtests wurden mit einer Stift-Scheibe-Anordnung und unter folgenden Versuchsbedingungen durchgeführt: 5, 10 bzw. 15 N Kraft, eine Reibgeschwindigkeit von 0,8 m × s−1 und eine Reibdistanz von 2000 m unter trockenen atmosphärischen Bedingungen. Die Ergebnisse zeigen, dass das mechanische und tribologische Verhalten der Epoxy-Komposite mit Mikro-Füllern besser als das der mit Nano-Füllern war.
