Fiber Fabric

The tensile properties of quartz fiber fabric-reinforced resin composites at high temperature were studied. The effects of specimen type and dimension, temperature loading procedure, holding time and loading rate on the tensile properties of the composites at high temperatures were analyzed through series of comparative experiments, the tensile test parameters were determined. Chinese national standard for high-temperature tensile property testing of the composites was compiled based on the data collected. According to the established standard, the tensile testing at 500°C was carried out. Compared with the tensile properties at room temperature, the tensile strength and tensile modulus of the composite at high temperature decreases significantly, with the tensile strength decreasing by about 42.32% and the tensile modulus decreasing by about 24.18%. This is mainly due to the high temperature which causes part of the resin matrix to pyrolyze and detach from around the fiber, thus losing the integrity of the material. In addition, this national standard for high-temperature tensile properties has some general applicability to different types of fiber-reinforced resin composites.

Rupture Behavior

Austenitic Alloys 230 and 617 have been identified to be the two most suitable structural materials for heat exchanger application within the purview of the next generation nuclear plant (NGNP) program. The NGNP program is aimed at developing electricity and hydrogen using heat from very-high-temperature-reactor (VHTR). A maximum operating temperature of 950 °C has been recommended to achieve the highest possible efficiency in both electricity and hydrogen generation. The identification of Alloys 617 and 230 as heat exchanger materials was based on their excellent resistance to high-temperature degradations including creep, stress-rupture, fatigue and tensile deformation. Extensive efforts have been made to evaluate the creep and stress-rupture behavior of both alloys at temperatures relevant to the NGNP application. This paper presents the results of stress-rupture testing involving these alloys as functions of applied stress and temperature. The time to rupture was gradually reduced with simultaneous increase in stress and temperature, leading to a gradual reduction in the Larson-Miller-Parameter (LMP) indicating enhanced rupture tendency.
