The thermal expansion behavior of 10 and 20 volume percent (v/o) Al{sub 2}O{sub 3} particle reinforced composites are studied. It is shown that the prestraining induce an increased coefficient of thermal expansion over the complete temperature range studied. The results are analyzed in terms of the fraction of broken particles, temperature range and volume fraction of particles o the coefficient of thermal expansion of the composites and compared with the CTE data available in the literature.
