Abstract: Composites are nowadays widely used in primary structures. For safety reasons, the characterization of these materials under fatigue loads is being a very important task. The main advances in this field have been made in glass fiber composites, due to their use in turbine blades, where the fatigue is a crucial factor. The characterization of a unidirectional carbon fibre composite material under fatigue loads is presented in this paper. The objective of the study is to obtain the S-N curve of the material at several frequencies and for different fibre orientation angles. For this purpose, fatigue tests under tension-tension at 0, 15 and 45 degrees for several frequencies (10Hz, 15Hz and 18Hz) have been carried out.
