Toughening by Aligned, Frictionally Constrained Fibers
The Mode-I fracture toughness of a brittle material reinforced by aligned brittle fibers is studied theoretically. The fibers are assumed to slip relative to the matrix when a critical interface shear stress is reached, and the toughening action of the fibers is presumed to be due to bridging of crack faces in the vicinity of the crack front. The toughening due to the fiber reinforcement is related to basic parameters associated with the related problem of steady-state matrix cracking in the presence of intact fibers. Bridge lengths at fracture and fracture resistance curves are calculated. Keywords: Fiber reinforced composites, Matrix materials, Crack propagation. (aw)
