The objective of the research work was to investigate the effect of ageing temperature and amount of carbon black (CB) on fatigue behaviour of Al/CB composites. The Al/CB composites were synthesis by using liquid metallurgical technique and characterised for fatigue properties using rotating beam fatigue machine at room temperature. The result shows that CB and ageing temperature increasing the fatigue life of the Al/CB composites due to its formation of precipitation during ageing process. The ageing temperature of 170?C gives higher fatigue life compare to ascast condition but over ageing temperature 270?C gives lower fatigue life. The addition of CB shows fatigue strength is improved significantly. The fatigue fracture surfaces were studied using electron microscope for detection of failure mechanism.
