To suppress thermal deformation, composite materials that has negative longitudinal coefficient of thermal expansion are layered with material that has positive Coefficient of Thermal Expansion (CTE). Assuming steady temperature fields, beam with no strain at central axis and no curvature can be designed. In unsteady temperature fields, it is possible to suppress thermal deformations while lowering thermal stresses. If it takes a long time until the temperature distribution get steady, the beam should be designed with considering unsteady temperature distributions because the beam that was designed with considering only steady temperature distribution could have large thermal deformations in its transitional period. For suppressing thermal deformations, interlaminar shearing stress, and interlaminar moment, materials with large Young's Modulus, CTE, and thermal conductivity are effective to use for low temperature side, oppositely, materials with small Young's Modulus, CTE, and thermal conductivity are effective to use for high temperature side., 資料番号: AA0063824014, レポート番号: JAXA-SP-07-008E}, pages = {142--149}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Minimization of unsteady thermal deformation by using laminated structures under the stress restrictions}, volume = {JAXA-SP-07-008E}, year = {2008} }
