== Abstract ==

There are several ways to obtain the fatigue life behavior of composite materials, such as the application of classical theories or complex progressive damage models. Recently, constant life diagrams have demonstrated good effectiveness in predicting the fatigue life of CFRPs. Nevertheless, the large number of tests required, and the time necessary for the characterization, makes this method very expensive in terms of time and resources.
The aim of this work is the evaluation of accelerated characterization techniques in addiction with statistical methods, to obtain constant fatigue life diagrams of CFRPs, with a reduced number of tests and a shorter characterization time.
The results show that, combining universal and accelerated testing techniques with statistical methods, it is possible to obtain constant life diagram for the whole range of tension-tension, tension-compression, and compression-compression loading modes, with a reduced number of tests. Moreover, it is observed that, the accelerated characterization techniques show a fatigue life limit similar to the conventional ones.

 De cualquier manera, se observa que, los métodos de fatiga acelerada, permiten construir diagramas de vida constante fiables para el diseño de vida a fatiga a alto número de ciclos, en un tiempo menor que los métodos estándar. Por otra parte también se  observa que la utilización de los métodos clásicos de cálculo de fatiga en composites, puede sobreestimar el cálculo de vida sobre todo en relaciones de tensión donde la tensión media y alterna son similares, (''R''=0,1 y ''R''=10), pudiendo dar origen a fallos de diseño por rotura a fatiga.
