| Abstract Scope |
Carbon-fiber reinforced polymer (CFRP) composites are commonly used in high performance applications. Although offering several advantages (i.e., superior specific properties and improved structural rigidity), CFRP composites exhibit poor thermal stability due to a low matrix thermal decomposition temperature. Their effective operating temperature can be raised by applying an external protective thermal barrier coating (TBC) layer. Conventional TBC materials include aluminum oxide, yttria-stabilized zirconia, and mullite owing to their high melting points and low thermal conductivities. Characterizing the thermal responses of TBC-coated CFRP composites before their implementation is critical to ensure their proper and reliable function at high temperatures. This work proposes a two-step hierarchical multiscale model framework to determine the effective properties and characterize the global thermal response of TBC/CFRP laminate. This multiscale framework consists of two hierarchically coupled analyses namely: the NASA multiscale analysis tool (NASMAT) and Abaqus. NASMAT is a multiscale recursive micromechanics software that will be used to determine the effective properties of the TBC and CFRP using the generalized method of cells (GMC) family of micromechanics approaches. Abaqus can then be used to perform static/transient heat transfer analysis using these effective TBC and CFRP properties. The model prediction will be validated with previously published experimental results (Kim et al., Compos B Eng, 225, 109308). Developing this framework for TBC-coated CFRP composites will improve their technological readiness level. This will allow these materials to be implemented in extreme environments with a high degree of confidence that they will not undergo unexpected catastrophic failure. |
