The use of a composite with an inorganic matrix as a structural material in high-temperature applications is investigated. The inorganic compound used as a matrix of the composite is easy to use because it can be cured at only 150 °C. In this study, an inorganic-based composite is filled with aluminum particles. The physical properties of the composite were tested before and after heat treatment. The results of high-temperature acoustic tests show that the elastic modulus of the composite containing aluminum particles becomes large after the heat treatment. Also, other results show that as the volume fraction of aluminum particles increases, the coefficient of linear expansion increases and the electric resistivity decreases.
