A strategy for accurate, efficient and economic thermal investigation of hybrid composite structures by means of the Finite Element Method (FEM) will be presented. It includes test prediction, validation tests, validation analysis, and an industrial application. Drawbacks of commercial software codes are identified and current research work for the solving of these disadvantages are presented. In design and development of aircraft structures requirements like enhancement of safety, cleanliness and stiffness as well as reduction of mass, fuel consumption, production and manufacturing costs, to name a view, are major issues for basic conceptual decisions. Though the ways to cope with these problems can be manyfold there are two specific topics that are pursued in industry which are also subject to resent research work at the German Aerospace Center (DLR) Institute of Composite Structures and Adaptive Systems. These are: 1. increased usage of composite materials in a wide range of structural parts of airframe structures for weight reduction. 2. reduction of development costs by minimizing the amount of experimental testing - especially for large scale structures - based on reliable simulation abilities.
