(a) Stress–strain curve for a small CF bundle (tow size of 0.4k) and (b) the corresponding modulus versus strain, considering a cross section of 0.8 mm2 and a bundle length of 80 mm. SAXS scattering intensity along the (c) equatorial and (d) meridional directions as a function of the scattering vector magnitude for each loading step. |
