2024年8月1日 · In this paper, a novel strategy was explored for the photocuring of 3D printed h-BN/PVSA slurries into complex structured PDCs green bodies using PVSA as the matrix and h -BN powder as the filler. Subsequently, these 3D-printed PDCs' green bodies were pyrolyzed and transformed into h -BN/SiCO composite ceramics with complex shapes.

2024年5月17日 · Incessant fiber-reinforced ceramic matrix composites (FRCMCs) are a type of robust ceramic material that derives its toughness from continuous fiber reinforcement and a well-optimized and weakened interphase between the Silicon Carbide (SiC) matrix and fibers.

2017年2月14日 · In this work, molecular dynamics (MD) based on empirical potential and first principle calculation were combined to investigate amorphous SiC x O 6/5 ceramics. The amorphous structures of SiCO...

2024年7月3日 · In the course of this work we are investigating amorphous SiCO formed via polymer-to-ceramic route. Previously a considerable amount of work has been done on structures of stoichiometric amorphous SiCO and a "perfect" random network was obtained (experimentally as well as supported by computational work) up to the phase content of 33 mol-% SiC.

2021年1月1日 · Effects of the polymer infiltration processing (PIP) temperature between 850 and 1050 °C on the mechanical and thermal properties of Nextel 312 fibre SiCO ceramic matrix composite were studied. The aim was to optimise the material system for its proposed application as a mechanical gas-seal at temperatures up to 900 °C.

2023年10月13日 · In this paper, the influence of polyvinyl silicon acetylene (PVSA) content in the photosensitive resin system on the performance of 3D-printed SiCO ceramics has been explored. The formulation of the photosensitive resin was further optimized and on the basis of modification, the two-dimensional filler h-BN was introduced.

In this study we investigated methods of forming matrices of SiC/SiC composite, which have recently attracted considerable attention as high temperature structural materials that can be used in airplane engines etc. We examined ways of balancing the formation of the dense, strong microstructures with the infiltration into fibrous preforms.

2011年4月4日 · We present combined modeling and simulation studies of Li insertion in amorphous SiCO ceramics. Atomistic models of amorphous SiCO with and without so-called “free” carbon have been crafted using a network modeling approach and subsequently relaxed and optimized within density functional theory.

2024年8月1日 · This study not only achieved the preparation of high-performance SiCO ceramics but also extended the application area of 3D printing polymer-derived ceramics by testing and analyzing the electrical and thermal conductivity of SiCO ceramics.
