A kinetic energy absorption method includes receiving a force from kinetic energy at a composite article and distributing a load associated with the force across a designated pattern of lower strength length portions or lower modulus length portions of fibers within the composite article, where the load is distributed by: plastically deforming a ply and a matrix material; separating multiple substantially parallel fibers at the lower strength length portions or plastically stretching the multiple substantially parallel fibers at the lower modulus length portions; and creating gaps in the ply where the multiple substantially parallel fibers are separated or creating shear boundaries in the ply where the multiple substantially parallel fibers are plastically stretched.
