ZL301 alloy was selected as the base matrix.The M40 Jcarbon fiber preform was woven by 2.5D shallow cross-linking

three-dimensional orthogonal and three-dimensional five-direction.The vacuum pressure infiltration method was used to prepare 3D-C

f

/Al composite with a fiber volume fraction of 50%.The effects of fabric structure on the microstructure and compressive strength of C

f

/Al composites were investigated.The results show that the fabric structure has a great influence on the density and microstructure of C

f

/Al composites.The C

f

/Al composites with three-dimensional orthogonal structure has the highest density and compressive strength

which are 99.2% and 417 MPa

respectively.The C

f

/Al composites with 2.5D shallow cross-linking structure have the lowest density and compressive strength of 95.3% and 99.8 MPa

respectively.
