In this study, the leak properties through CFRP cross-ply laminates under biaxial loadings were investigated. Leak analysis for damaged CFRP laminates has been developed based on the opening displacements of matrix cracks acting as leakage paths. The leak rate through the damaged laminates under biaxial loading was measured in an experiment using cruciform specimens at room temperature. Calculations of the leak rate based on the leak analysis coincided well with experimental results, showing the leak rate to be closely dependent on crack openings in the laminates. Numerical results indicate that an increase in propellant leakage can be caused by the enlargement of crack opening displacements due to mechanical and thermal loads, increase of crack density and decrease of temperature.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ISSNの誤記:
