Abstract

Control of thermal expansion coefficient of materials is widely needed in the industrial field. Many materials with negative thermal expansion coefficient have been reported. These materials are useful for the secondary phase of composites, because small amounts can effectively offset thermal expansion of the matrix. Materials having a negative coefficient of thermal expansion are classified by their mechanism, i.e. phase transition and framework structure. Composites containing materials with negative thermal expansion coefficient have been reported. Their thermal expansion coefficient was between the value predicted by rule of mixture and Tuner equation. Discussion of interaction of the interface between the filler and the matrix is expected as a future challenge because prediction of the accurate value is difficult.
