A vehicular spring leaf comprises a pultruded beam that has about 40-75% by volume filamentary solids of a first modulus and a remainder fraction comprising continuous organic solid of a second, lower modulus that binds together the filamentary solids. A first portion of at least about 80% by weight of the filamentary solids is a multitude of discrete, tensilely stressed filamentary solids, densely packed substantially uniformly throughout the organic solid and coextending the beam longitudinally in a plurality of planes that accept tensile or compressive stress, respectively, upon a flexure of the leaf that bends the beam. A second portion of up to about 10% by weight of filamentary solids is randomly oriented on a surface of the beam, and a third portion of up to about 10% by weight of filamentary solids is woven oriented substantially across one another in one of the planes.
