2.5D woven fabric Cf/Al composites with 2.5D graphite fiber fabric as reinforcement and ZL301 as matrix alloy was fabricated by the vacuum pressure infiltration method. The density and microstructure of the composites, which were prepared with three fabric temperature level, was investigated. The crystal structure and composition of the interfacial product was revealed. The quasi-static tensile test and electron fractography was carried out to analyze the mechanical behavior of the composite along the warp and weft direction. The results indicated that the fabric structure can be maintained well, in which the fibers distributed in matrix alloy uniformly. With the increase of fabric temperature, the density of the composites was improved slightly while the relative amount of interfacial product, which was identified to be Al4C3 phase with rod shape, increased obviously, which lead to the reduction of mechanical properties both in warp and weft direction. The tensile strength in warp direction has been proven to be higher than that in weft direction. The stress-strain behavior in warp direction exhibit an significant nonlinear characteristic. The tensile deformation process both in warp and weft direction can be divided into three stages, i.e. the initial elastic deformation segment, the middle elastoplastic deformation segment and the final damage and fracture segment.
