Abstract
The present invention provides a fiber reinforced polymer composite having a plurality of layers containing a plurality of fibers. The layers may be configured to maintain predetermined load sharing ratios among the layers at different load levels to produce a gradual load transfer between the different layers during the progressive failure of the composite. The composite is comprised of mono-fibers and the load sharing ratios of the layers have coefficients of variation that are less than 20%.
