Abstract
A method of making a composite article having at least a minimum selected impact strength by first obtaining the impact energy absorption/shear strength relationship for the collimated filaments and matrix material comprising the article. Impact strength is improved by the selection of the relative bond strengths between constituents and the orientation of selected matrix materials relative to the impact surface of the article.
