Abstract

An elastic spring element includes a fiber-reinforced ceramic that is resistant to temperatures greater than 1,000° C. The fibers are in the form of endless fibers and the elastic spring element has a corrugated geometric shape. The elastic spring elements may be used for sealing a control surface against hypersonic flow.
