2.5D shallow-bend joint woven C

f

/Al composites with graphite fiber as reinforcement and ZL301 as matrix alloy were fabricated by the vacuum pressure infiltration method

and the ratio of warp/weft fibers of 2.5D shallow-bend joint woven preform was 54%∶46%

65%∶35% and 78%∶22%.The relative density

microstructure and mechanical properties of 2.5D shallow-bend joint woven C

f

/Al composites with different ratio of warp/weft fibers were investigated.The results show that the relative density of 2.5D composites is decreased with the increase of warp fiber volume fraction

and the density of C

f

/Al composites with warp/weft fiber ratio of 54%∶46%reaches the maximum value of 98.5%.Absence of infiltration defect in the microstructure can be observed

and it has the desirable infiltration effect.The ratio of warp/weft fibers has a great influence on the warp and weft tensile strength of 2.5D-C

/Al composites.The 2.5D-C

f

/Al composites with warp/weft fibers ratio of 65%∶35% have a warp tensile strength of 380.6 MPa and a weft tensile strength of 245.6 MPa

presenting the satisfied comprehensive properties.The tensile fracture surfaces are uneven and show a moderate interfacial bonding strength.
