The bottom ply and the top ply have fibers in a substantially orthogonal direction to the longitudinal direction of the article. At least one ply has the fibers substantially in the same direction as the longitudinal direction of the article. At least one of the plies having fibers substantially in the longitudinal direction includes particles selected from the group of thermoplastic tougheners, nano particles, micro particles, elastic particles, elastomer particles and polymer particles or a combination. Also a method of forming an article on a tool.
