In order to produce metal-matrix-composites by a simple method, it has been attempted to fabricate an Al/Ti composite by pressing alternately multilayered pure Al and Ti foils at room temperature. The thickness of Ti foil used, was 10, 25 or 102 μm for the constant thickness, 92μm, of Al foil to fabricate Al/Ti composites with various volume fraction. Effect of Ti foil thickness on fabrication and bending properties of multilayered Al/Ti composites has been examined. Three inflection points are detected on nominal compressive stress-displacement curves for alternately multilayered Al/Ti foils. Joining of the multilayered Al/Ti foils is attained after the 3rd inflection point. Stress at the 3rd inflection point rises with increasing thickness of the multilayered Ti foils and is proportional to the volume fraction of Ti phase. Multilayered Al/Ti composite with Ti flakes of 52.1 volume percent could be fabricated at nominal compressive stresses higher than 3 GPa at room temperature. The bending strength of multilayered Al/Ti composites obtained increases with the volume fraction of Ti phase.
