Abstract

In this study, the tribological behavior of epoxy composites was experimentally studied and analytically modeled using finite element techniques. Wear test and modeling were carried out for pin-on-disk configuration and under identical boundary and test conditions. The tribological elements consisted of Al2O3 filled epoxy composite pin and a steel disk. The tribological system was modeled two-dimensionally and a quasi-static analysis was performed. The wear amount and the developed stresses during the rubbing process were predicted and compared with the experimentally determined results. A good correlation between the experimental and analytical results were observed.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie wurde das tribologische Verhalten von Epoxid-Kompositen experimentell untersucht und analytisch mittels Finite Elemente Techniken modelliert. Die Verschleißversuche und die Modellierungen wurden anhand einer Stift-Scheibe-Konfiguration unter idealen Rand- und Versuchsbedingungen durchgeführt. Die tribologischen Elemente bestanden aus einem Al2O3-gefüllten Epoxid-Komposit-Stift und einer Stahlscheibe. Das tribologische System wurde zweidimensional modelliert und es wurde eine quasi-statische Analyse durchgeführt. Der Verschleißabtrag und die sich während des Reibprozesses entwickelnden Spannungen wurden vorhergesagt und mit den experimentell ermittelten Ergebnissen verglichen. Es wurde eine gute Korrelation zwischen den experimentellen und analytischen Ergebnissen festgestellt.
