"lightweight, high modulus, highly electrical, thermally conductive... floating catalyst chemical vapor deposition purified, functionalized... stretched in chlorosulfonic acid containing poly(p-phenylene-2,6-benzobisoxazole), then mechanical densification improving interfacial interactions, nanotube alignment, densification within fibers, improving quasi-static, dynamic strength... Cunniff velocity >1100 m/s... far exceeding that of Kevlar... high strain rate battlefield protection, space debris capture"
