The liquid extrusion infiltration technique was used to fabricate two 2D CF/Al composites with T700 and T300 carbon fiber fabrics. Microstructure examination demonstrated their different macroscopic infiltration morphology, but the infiltration effect was perfect. The coefficient of thermal expansion of those two composites was shown to be much lower than that of the matrix alloy below 673 K (400°C). At a temperature higher than 673 K (400°C), this value for a T300 CF/Al composite was equivalent to only 22.6%, which was much smaller than that of the matrix alloy. The ultimate tensile strength of T700 CF/Al and T300 CF/Al composites was improved by factors of 2.007 and 2.467 than that of the matrix alloy, respectively. The differences in the thermal expansion coefficient and ultimate tensile strength stem from carbon fiber volume fractions and its grades of the two different fabrics. The fracture morphology of tensile specimens was also influenced by the fiber orientation in fabrics. A T300 CF/Al composite displayed better tensile and thermal expansion properties than a T700 CF/Al composite, which were prepared and designed for further industrial applications.
