A micromechanical model extends a hybrid fiber array to describe the microstructure of a blended yarn in which the low elongation to break (LE) fibers are fragmenting. The mixed array consists of a small number of high modulus LE fibers dispersed among high elongation to break fibers. The LE fiber fragments slip relative to neighboring fibers in areas near the fragment tips. The fiber array compresses laterally, and frictional forces at slipping fiber to fiber contact points follow Amontons' law. Researchers identified solutions to a dimensionless boundary value problem for deformation in a unit cell of the fiber array and determined the contribution of LE fiber fragments to the load carrying capacity of the fiber array. 25 refs.
