Abstract
Due to the large difference in the coefficients of thermal expansion of the continuous fibers and the metal matrix in metal matrix composites, a large residual stress pattern could be expected when the composite is cooled from the fabrication temperature to room temperature. This paper will first briefly describe the x-ray techniques used to measure the residual stresses and then present and discuss the residual stress results obtained. Experiments were done on aluminum, magnesium and titanium matrix composites. This paper will concentrate on the measurements in the aluminum graphite system. It should be noted that the reported residual stresses are only from the matrix phase due to the difficulty introduced by the large texture in the graphite fibers.
