The approach pointed out the leading role of the temperature and soaking time in the densification process. Temperatures higher than 785 8C lead to oversintering, characterized by the presence of intergranular pores; the amount of porosity increases with longer soaking times. On the contrary, the volume fraction of reinforcement and the applied pressure do not significantly affect the sintering behaviour. Future developments of the present research will include the characterization of the mechanical and electrical properties of the composites even at high temperatures. This will contribute to establish quantitative microstruc￾ture–properties relationships. References [1] Bansal NP, Setlock JA. Fabrication of fiber-reinforced celsian matrix composites.
