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. The 4- and 6-ply samples in the above graph were loaded in the transverse direction. The 4-ply sample here has similar tensile performance as the 4-ply sample in Figure 1, which is expected because the two samples contain an equal balance of 0- and 90-degree fibers.
