This single-ply tape can be layered to form multi-axial laminate sheets and rolls by stacking layers of tape in varying directions and applying heat and pressure. 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.
