Abstract:
To estimate the heat resistance of continuous fiber bar, tensile strength of several types of continuous fiber bars were examined under high temperature and ordinary temperature after heating and cooling. The temperature range was 60 to 400 C. It was found that the tensile strength of organic binder bar was recovered under ordinary temperature after heating and cooling compared with higher temperature. Organic binder bars showed little decrease of tensile strength at high temperature. Carbon and glass fibers have more heat resistance than aramid fiber bars.
