Notes:
Copper and 2024 aluminum alloy were melt-infiltrated into porous β-SiC to form SiC/Cuand SiC/Al composites. The porous β-SiC was prepared using Moso bamboo as the bio-templateand had structural characteristics of bamboo. The Cu infiltration occurred as low as 1100°C andbecame significant at 1200°C. After infiltration at 1300°C for 4 h, there was still ~5 % of residualporosity. For the composites with low degree of metal infiltration, the samples fractured like thebamboo-structured porous SiC. For the composites with high degree of infiltration, the samplebehaved like monolithic copper. In the infiltration of Al alloy, infiltration occurred at 900°C. HigherInfiltration temperatures would result in significant formation of Al4C3, which graduallydecomposed in air
