Resin concrete has been used in machine tool structures tool structures in order to improve the dynamic properties and to reduce the lead time of producing. It has been, however, pointed out by MTIRA that the composite structure made of steel combined with resin concrete is inferior to the structure made of conventional materials in the thermal deformation. In this paper, the thermal deformation of a structure consisting of steel and resin concrete has been experimentally investigated using a simple model. It is concluded from the results that large thermal expansion and low thermal conductivity of resin concrete compared with steel or cast iron induce the large thermal deformation if the application of resin concrete is not suitable. In addition, some useful applications of resin concrete to the machine tool structures are proposed ; prevention of thermal deformation due to room temperature change, improvement of cooling efficiency, etc...
