| Research Abstract |
A new material referred to as ceramics resin concrete has been developed for use in some structures. This material consists of epoxy resin and ceramics, i.e., alumina, silicon carbide, zirconia, or a mixture of these. Some properties of the compound material were experimentally and theoretically investigated. In addition, a few application for industrial material have attempted. The results obtained are as follows.
(1) A practical manufacturing method for the ceramics resin concrete was established.
(2) Young's modulus was 60%, density was 95%, thermal conductivity was 50%, coefficient of linear expansion was 1.2 times, specific hear was 1.2 times, logarithmic decrement was 60 times and fracture toughness was 1.6 times, that of the used aggregate.
(3) The developed program can be used to estimate some of the fundamental thermal and mechanical properties from the physical properties and volume fluctuation of the constituent materials.
(4) Fracture toughness of the ceramics resin concrete was far better than ordinary ceramics, because of the crack extension resistance is increased by the crack deflection or microcracking.
(5) A large sized structure has been made with simple method and equipment, short working time and low cost.
(6) Tool life in a NC lathe with tool post using this material was five times that of conventional NC lathe.
