摘 要：Lightweight high-strength and tough composites have enormous potentials in a multitude of fields in-cluding biomaterials,sporting goods,aerospace and automobile ***,we present a strat-egy to develop a novel bulk Al/SiC composite with a nacre/foam hybrid structure to combine excellent lightweight of foams with outstanding strength and toughness of *** reduce the adverse effect of foam pores on mechanical properties,we further propose to strengthen the foams with 3D nanofiber networks,obtaining a nacre/nanofiber reinforced foam ***,new particle-bubble co-assembly and selective infiltration technologies are proposed to prepare the novel nacre/foam and nacre/nanofiber reinforced foam *** nacre/nanofiber reinforced foam composite shows greater specific strength and toughness than the nacre/foam composite,conventional dense Al/SiC composites and many engineering *** approach opens a promising new avenue for the structure design and manufacturing of lightweight,high-performance structural materials.
