Abstract
Four kinds of Cf/Mg composites with different fabric architectures were fabricated by liquid-solid extrusion following vacuum infiltration (LSEVI) technique. The influence of fabric architecture on compressive properties of Cf/Mg composites was investigated, and the microstructure and failure surfaces were examined by SEM. The results showed that Cf/Mg composites were anisotropic material and the fabric architecture had great influence on their compressive performance. Moreover, fabric crimp had a negative influence on compressive properties of Cf/Mg composite. The composite with non-woven carbon fabric perform had the highest compressive strength (XY direction). Compared with 3 K plain-woven carbon cloth composite whose fiber bundles had 3000 monofilaments, 1 K plain-woven carbon cloth composite had better compressive properties. The analysis of failure surface indicated that the failure modes of Cf/Mg composites were mainly shear failure and delamination failure.
