Description
Summary:Carbon fiber reinforced polymers (CFRP) are increasingly employed within the aerospace industry. Therefore, a lot of Finite Element models have been developed in order to understand their material removal mechanisms. Among the scientific issues faced by these works, the identification of friction coefficients remains a strategic field of research. This paper aims at characterizing the friction properties between composite and cutting tool materials. The specific tribological conditions during machining of such heterogeneous materials are discussed in the paper, especially the configuration of the tribosystem. This paper presents the development of an original tribometer designed to simulate conditions corresponding to machining of randomly structured CFRP materials. It provides quantitative values of friction coefficient and heat partition coefficient depending on sliding velocities.
