"high-performance fibers embedded in polymer sheets stacked and pressed into 1 extremely lightweight, durable multilayer... prevent cracks from spreading between composite layers by up to 60% by depositing chemically grown (vapor deposition) carbon densely packed nanotubes between composite layers... composite 3 mm thick comprising 60 layers, each made from stiff, horizontal fibers embedded in polymer sheet... lighter, stronger airplanes"
