Results showed that the twisting cannot be fully transferred through the whole fiber and the CNTs within fibers possess non-uniform alignments in radial direction. Effective twisting depth was determined from the residue strain distribution within fibers. Larger surface twisting angles can result in higher residue strain, better alignment degree, and deeper twisting depth. This research suggests a balance should be built between the enhancement of CNT interactions and the increase of defect density to obtain high-performance fibers.||URI:||https://hdl.handle.net/10356/101174
