Abstract
X CONGRESO NACIONAL DE MATERIALES COMPUESTOS. Celebrado en Algeciras los días 2, 3, 4 y 5 de julio de 2013Composites 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.Junta de Andalucía P08-TEP-4071Fondo Social Europeo P08-TEP-407
