A Novel Material Preparation of Density Ceramics and Fibre Joining

Abstract:

The joining materials of density ceramics and woven fibres would be potential value as sealing parts for thermal protection system application in aerospace field. Based on ZrO₂-Al₂O₃-SiO₂ phase diagram, the ceramics matrix and interlayer compositions were designed. Using the absorber-microwaves properties of Al-Si alloy, the joining of ZTM ceramics and fibre materials with interlayer was achieved by microwave hybrid heating method. The experiment results indicated that the interlayer ingredients were mullite, zirconia and alumina after microwave sintering. The strength of joint specimens was related with the interlayer compositions and the specimen preserved elasticity property according to the test result of universal testing machine. The joint mechanism of interlayer by microwave sintering was discussed in this paper.
