Resin concrete has been widely used in machine tool structures in order to improve the dynamic properties, reduce the lead time of production and reduce thermal deformation. It has been pointed out, however, that Young's modulus of concrete is about one-seventh that of cast iron and thus, that resin concrete is inferior to conventional materials in static stiffness. Therefore, in this paper, a new material referred to as ceramic resin concrete has been developed for use in precision machine tool structures. This material consists of epoxy resin and ceramics, i.e., alumina, silicon carbide, zirconia or a mixture of these. A practical manufacturing method for the ceramic resin concrete was established. It is concluded from the experimental results that the Young's modulus is three times and the compressive strength is two times that of conventional resin concrete.
