Abstract
Toughening ceramics has been a long-standing challenge. By chemically infiltrating B4C into aligned carbon nanotubes (CNTs) sheets, we fabricate a novel CNT/B4C composite with a fracture strength approaching the theoretical maximum of B4C matrix. The CNT/B 4C composites simultaneously possess a strongly bonded tube/matrix interface and an amorphous, crack-free B4C matrix. The fracture strength of the CNT/B4C nanowires is about 1-2 orders of magnitude higher than that of the bulk B4C.
