Abstract

FE macro/micro models for contact temperature analysis of a steel asperity sliding over a normally oriented CF/PEEK composite surface Z. Nederi, K. Varadi' & K. Friedrich^ lBudapest University of Technology and Economics, Hungary 2 University of Kaiserslautern, Germany Abstract FE contact and thermal macro/micro models have been developed to study the real thermal behaviour of a fibre/matrix micro-structure under sliding motion of a steel asperity. At first the contact parameters were evaluated using an approximate contact technique, followed by a transient thermal FE evaluation. The latter considers the heat partition between the steel asperity and the real fibre/matrix micro-environment of a normally oriented CF/PEEK composite. 1 Introduction The friction and wear behaviour of fibre reinforced composites has been intensively studied in the last couple of years in order to improve the tribological performance of these materials. In particular, different efforts were undertake
