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.
