Abstract
A fiber/metal laminate composite material is comprised of a plurality of metallic layers, reinforced with a plurality of fiber layers. The metallic layers are preferably aluminum, while the fibers in the fiber layers are preferably comprised of an aramid. The fibers are bi-directionally oriented. To provide the laminate with superior fiber failure resistance characteristics, the laminate is post-stretched along a post-stretch axis which bisects the two fiber axes.
