Abstract
This paper reports on the tensile toughness of various fibers calculated using the calculated using the stress-strain curves published already. The influence of tensile test conditions such as strain rate, temperature and humidity on their tensile toughness have been analyzed.
As a result, it was concluded that the testing environment as well as the strain rate did significantly affect the tensile toughness. The evaluation of properties using tensile toughness of each fiber showed different with it of tensile strength and elongation for the fibers. Thus, we proposed that the tensile properties of a fiber should be evaluated not only by strength and elongation, but also by toughness.
