Abstract

In this paper a simulation strategy for composite structures will be presented taking into account all thermal aspects, which may occure from manufacturing to in-service. Focus herein is laid on the thermo-elastic simulation of the spring-in effect on large airframe structures based on the FEmethod. Besides the identification of curing parameters validation testing will be dealt with in an overview manner. Results of spring-in investigations performed at the DLR Institute of Composite Structures and Adaptive Systems will be presented. They are based on parameter determinations by means of experimental testing and the application to a relevant airframe structure.
