Composite materials have a great demand in engineering applications because they have features that conventional materials do not have. Four carbon fiber woven reinforced aluminum matrix composites were fabricated using P/M technique. Proposed reinforcements were a six-axial woven fabric similar to a spider-web, two quad-axial woven fabrics and one tri-axial woven fabric. All composites were tensile tested. Engineering stress-strain plots were obtained and it was found that increasing the axial fibers in a woven enhanced the isotropicity of the composite properties. QWF1 and TWF were isotropic in modulus, with values ranging between 10%--14% and 14%--21% respectively in comparison with the highest value for each weave. QWF2 could be considered quasi-isotropic with 11%--23% of variation in comparison with highest value obtained in this weave. TWF had highest strength at about 153.73 MPa, and SWF had the highest values of modulus of elasticity, 55.7 GPa approximately. All weaves proposed were isotropic in Yield strength as it was expected. QWF1 and SWF with variation in values of 17% and 19% maximum respectively, had the best isotropic properties in strength though they did not reach the values higher than the unreinforced matrix. Although, it was possible to fabricate carbon fiber woven reinforced aluminum matrix composites by P/M technique, the anticipated advantages could not be obtained for this fabrication method because carbon fibers do not withstand high pressures in the transverse directions. In addition, the volume fraction failed to exceed 3.5% due to fabrication process limitations.
