However, most of the conventional methods are challenging to apply to such objects due to the scale effect of the gauge length (distance between grips) on the static modulus when measuring fiber deformation by moving the grips (crosshead movement). This paper examines several advanced high-modulus fibers, including Twaron and Armos, along with introducing a model for calculating real modulus from measured values.
