摘要：

The compressive behavior of closed-cell copper-coated carbon fiber/aluminum composite foam with 1 and 5 wt % fibers was assessed under quasi-static and high-strain-rate loading conditions The 5 wt % fiber/aluminum foam exhibits higher plastic collapse stress The failure modes of fibers in the matrix were discussed A strain-rate effect was demonstrated for fiber/aluminum foam The strain-rate effect was more apparent at strain rates in the similar to ks(-1) range and is attributed to the rate sensitivity of dense fiber/aluminum composite and to the foam structure (C) 2010 Published by Elsevier Ltd on behalf of Acta Materialia Inc
