Figure 13
In situ scanning of bent PAN fibre. In the left-hand image the total intensities of the 002 reflection coincide with the volume function (no beam deconvolution required owing to the extremely small beam size). In the right-hand image the width is roughly constant for the straight (control) fibre, and shows a pronounced position dependence for the bent fibre. The effect increases with decreasing bending radius of the fibre (higher tension and compressive stresses). |
