| Abstract | ||||
| In the present work, the fatigue behaviour of pure aluminium reinforced with Sic fibers composite has been investigated. The composite was fabricated by squeeze casting technique with different values of fibers volume fraction Vf. Rotating bending fatigue test was used to compare the fatigue strength of the composite with matrix material. Fatigue fracture hrfaces of specimens were investigated by macroscopic and SEM observations. The influence of volume fraction of fibers on the fatigue life was discussed. The obtained results showed that, in comparison with pure aluminium, the fatigue strength at 10' cycles of the composites is superior by 9 1.3% and 90.2% fbr Vf = 45% and Vf = 3 5% , respectively. Fatigue crack does not propagate along the fibers-matrix interface, he propagates in the matrix. The fatigue strength ratio of Sic/& composites indicated about 0.71. | ||||
