Thermomechanical analysis of the high cycle fatigue behavior of a peek CF30 under compressive loadings

Résumé

The assessment of the fatigue life of structures made of short-fiber reinforced thermoplastics is a complex issue due to the non-linear dissipative behavior of the matrix and the heterogeneous distribution of fiber orientations. The aim of this study is to develop an approach for the high cycle fatigue design of PolyEtherEtherKetone reinforced with 30 wt % of short carbon fibers (PEEK CF30), for compressive loadings. This includes the assessment of the ability of the heat build-up technique to predict the fatigue lifetime. To our knowledge, there are no data in the literature for this material and these loading conditions. The results obtained in compression are compared to data obtained in tension. The effects of the loading direction from the injection direction and the load ratio are studied.
