In many manufacturing fields, i.e., space and airplane, automobile and electric engineering, the engineering use for laminated structures of different materials such as metals, plastics and composite materials becomes very common. If such a laminate is under any temperature change, the thermal stress is generated in it because the thermal properties such as thermal conductivity and a coefficient of thermal expansion of each component are generally quite different. This paper deals with the transient thermal stress analysis of laminates which are made of three components of finite length and manufactured at a certain constant temperature and then an upper and a lower components of the laminate are cooled and kept at 0℃ instantaneously, at the same time, side surfaces of the laminate are cooled by fluid of 0℃. The thermal stress and the temperature distribution at the interfaces between the components are examined from the numerical calculations in order to investigate the thermal strength of the laminate.
