This work addresses the structural analysis of lightweight CFRP composite structures that are exposed to thermomechanical load conditions and specifically refers to applications where thermal loads are caused by external heat sources. Such conditions are particularly challenging for CFRP materials, as their behavior is orthotropic and highly dependent on temperature. Thermal expansion can significantly contribute to the deformation state and stress development. However, typical structural sizing makes use of simplified uniform thermal conditions and thermal worst-case scenarios.

摘要

This work addresses the structural analysis of lightweight CFRP composite structures that are exposed to thermomechanical load conditions and specifically refers to applications where thermal loads are caused by external heat sources. Such conditions are particularly challenging for CFRP materials, as their behavior is orthotropic and highly dependent on temperature. Thermal expansion can significantly contribute to the deformation state and stress development. However, typical structural sizing makes use of simplified uniform thermal conditions and thermal worst-case scenarios.
