L\u2019objectif de cet article est de synth\u00e9tiser une \u00e9tude comparative de l\u2019effet de la fatigue en traction sur trois composites \u00e0 base de fibres de verre unidirectionnelles, fibres de verre serg\u00e9s et en fibres d\u2019aramide taffetas et de r\u00e9sine \u00e9poxyde. Pour mieux comprendre les diff\u00e9rents ph\u00e9nom\u00e8nes qui apparaissent durant les diff\u00e9rents essais, nous avons opt\u00e9 pour un suivi acoustique en faisant varier les nombres de cycles de fatigue de 100 \u00e0 50000. A cet effet, nous avons utilis\u00e9 trois capteurs externes pi\u00e9zo\u00e9lectriques reli\u00e9s \u00e0 trois amplificateurs de signaux, le tout reli\u00e9\u00a0 \u00e0 un syst\u00e8me d\u2019acquisition informatique. L\u2019outil acoustique nous a permis de comparer plus facilement les effets de la fatigue sur les trois mat\u00e9riaux. Il nous a permis de d\u00e9tecter en direct les diff\u00e9rents types d\u2019endommagements occasionn\u00e9s par la fatigue (fissuration matricielle, d\u00e9laminage, d\u00e9coh\u00e9sion et rupture des fibres). Les r\u00e9sultats de cette \u00e9tude\u00a0 mettent en \u00e9vidence les effets de la fatigue sur les trois mat\u00e9riaux, qui se manifestent par une diminution syst\u00e9matique des caract\u00e9ristiques \u00e0 la rupture de ces derniers, progressivement en fonction de l\u2019augmentation des nombres de cycles. Il s\u2019av\u00e8re aussi que les mat\u00e9riaux \u00e0 fibres de verre sont moins r\u00e9sistants que ceux \u00e0 fibres d\u2019aramide.<\/p>\n
