such a structure would clearly also provide a degree of ballistic protection simply due to thickness and as will be shown below for certain formulations of the composite the fibers may be treated in such a way that increases resistance to projectile spreading without losing structural strength such panels are a useful size to serve as sections of blast resistant barriers with a significant weight savings compared to concrete or steel barriers in addition to other significant beneficial characteristics thereby demonstrating the applicability of the novel frp composite structure as a blast barrier the fiber orientation for a blast resistant barrier preferably is oriented along the bending axis anticipated which for a barrier embedded in the ground is the vertical axis only the minimum necessary to keep the structure together in the other axis is desirable or to handle other requirements controlling weave geometry to achieve alignment in multi layer laminates is not common which is one reason existing composites are not effective blast barriers to achieve the desired novel construction weave has to be procured with a given orientation and then the weave has to be applied to maintain that orientation as each ply is built up up to 40 or more plies although a range of fiber orientations will deliver useful results the inventors have found that a 89 vertical 11 horizontal fiber weave is near optimum for a blast barrier application while as little as 50 in the vertical direction is still beneficial in order to make a thick laminate 2 u2033 or more several layers of fiber weave are needed close to 40 for some tested versions the inventors have produced the inventors have also found that fiber weight per layer greatly affects the amount of resin which.
