Tensile modulus measures the ratio of stress to strain along an axis and is one way to quantify the strength and stiffness of an FRP material. The graph above shows the result of tensile load applied longitudinally to three laminate samples made with Polystrand™ continuous glass fiber reinforced polypropylene in 2-, 4- and 6-ply configurations, illustrated below.
