Microwave and conventional sintering of SiC/SiC composites: Flexural properties and microstructures

Effect of microwave sintering time on the flexural properties of the SiC/SiC composites

“…KD-I SiC fiber bundles (characteristics listed in [14]) are three-dimension and four-direction preforms (fiber volume fraction ~45%), coated with PyC as interface layers. Polycarbosilane (PCS, provided by National University of Defense Technology, China) with xylene as a solvent was used as the polymer precursor of the SiC matrix.…”

“…Yang et al [14] have studied the flexural strength and toughness of the microwave and conventional sintered SiC/SiC composites by PIP process and proved some advantages of microwave sintering. However, the effect of microwave sintering time at each PIP cycle on the mechanical properties or microstructures of SiC/SiC composites has not been involved.…”

High temperature digital image correlation evaluation of in-situ failure mechanism: An experimental framework with application to C/SiC composites

“…In recent years, various experimental methods such as tension [3][4][5][6], shear [7][8][9] and bending tests [10][11][12] have been developed to measure the fracture strength and fracture toughness of ceramic matrix composites. Tao et al found that the tensile strength of 2d-C/SiC composites decreased from 266 MPa at room temperature to 146 MPa at 1000°C [3].…”

A Comparative Study of Conventional and Microwave Sintering of BaCe1 − xGdxO3 − δ Ceramic

“…The microwave sintering can give rise to dense materials at lower temperatures and shortened sintering periods compared to those of conventional sintering [30][31][32][33]. Isolating materials such as silicon dioxide or alumina are supposed to be heated above 600 °C in order to generate time-dependent electric dipoles that can absorb the microwave energy [34].…”
