Abstract
The fracture energy of a porous silicon nitride with aligned fibrous grains was investigated, using a chevron‐notched‐beam technique. A crack was constrained to propagate normal to the grain alignment. The obtained fracture energy was ∼500 J/m2, which was ∼7 times larger than that of a dense silicon nitride with randomly oriented fibrous grains. The large fracture energy was attributable primarily to the sliding resistance associated with interlocking grains.
