Title: CARBON/CARBON COMPOSITE SPRING ELEMENT AND MANUFACTURING METHOD THEREFOR
Abstract:
[Problem] To provide a spring element that can be used repeatedly even in a high-temperature environment exceeding 1000°C, has high torsional rigidity that enables a large load to be supported, and can be used as a spring washer. [Solution] This spiral annular-shaped spring element is configured so as to comprise a two-dimensional carbon/carbon composite material having a stacked layer configuration in which layers are stacked in the center axis direction of the spring element.
