"As strong as styrofoam" doesn't really mean anything. Are you talking about tensile strength? Or about resistance to shear forces? Compressibility? I haven't found much data on the mechanical properties of aerographite, but the Young modulus given on Wikipedia seems way too low to withstand atmospheric pressure.
