摘要: The compressive deformation behavior of 0.5 wt.% graphene-reinforced aluminum-SiC hybrid composite foam under dynamic loading over strain rates 500-2760 s−1 was studied using a split-Hopkinson pressure bar unit. It found that the loading, plateau stress and energy absorption aluminum increased with rate. On other hand, densification did vary only marginally Further, it noted lower relative density more sensitive to lighter foams exhibited higher as compared heavier ones. were enhanced density. Present results showed is rate less coefficient, in scaling relation predict stress, range 0.2-0.5 for 500-2760 s−1.
