| Abstract: | The grooved-foil process is adopted to fabricate SiCf/Ti composite panel.The fiber to matrix interfaces and the matrix of the composites,prepared under different processing parameters,are analyzed,so that the optimum process parameters of temperature 925 ℃,pressure 100 MPa and holding one hour are obtained.Since the SiCf/Ti composite has superplastic property along the fiber direction,a SiCf/Ti composite monolithic with hollow structure is fabricated by consolidation,hot forming,Superplastic Forming(SPF) in sequence.And the feasibility of forming process was verified by investigating the microstructure and mechanical properties of the hollow structure. |
