Main Article Content
Abstract
Synchrotron radiation was used to follow the change of c-spacing of meridional reflections with applied tension which allowed the crystal strain to be calculated. The crystal modulus values of Technora, Twaron 81 and 83 fibres were determined and compared to the fibre tensile modulus values. The crystal moduli of both Twaron 81 and 83 had similar values of 200 GPa where as that of Technora fibre was much lower at 105 GPa.
