Summary: Ceramification of polymer composites is an excellent approach for enhancing flame retardancy. The addition of low temperature softening glass frit in the composites plays a crucial role in the ceramification process. Ceramizable PE/WF composites were processed by mixing with three types of glass frit, and the formed ceramic residues were characterized. The density and strength of the ceramic increased with increasing sintering temperature, but were influenced by the wettability and fluidity of the glass frit. Adding glass frit can increase the thermal decomposition temperature of PE. X-ray diffraction analysis revealed the formation of a new phase of hydroxyapatite in the ceramifiable PE/WF composites by adding phosphate glass frit, improving the self-supporting properties of the ceramic residues.

Summary: The dielectric performance of silicone rubber composites can be significantly enhanced by adding one-dimensional carbon nanotubes (CNTs) and zero-dimensional copper calcium titanate (CCTO) ceramic fillers. The addition of CCTO particles allowed for the uniform dispersion of CNTs, resulting in improved dielectric performance and good mechanical properties and thermal stability.

Summary: The tunable porous structure of SiCN(O)-derived ceramic aerogels was investigated by changing the molecular structure of the polysilazanes from linear to branched in this study. The effect of molecular structure on the thermal insulation properties of ceramic aerogels was also studied. As the percentage of branched molecular structure in the polysilazane precursor increased, the internal microscopic pore structure of the aerogels changed from macroporous to mesoporous. The specific surface areas and pore volumes of the ceramic aerogels prepared with different precursors increased after pyrolysis at 1000 degrees C, and the thermal conductivities increased slightly.

Summary: The mechanical behavior of fiber-reinforced polymer composites modified with ceramic fillers at different temperatures and strain rates was investigated. Dynamic and quasi-static compressive tests of B4C-talc modified high-silica/boron-phenolic composites were conducted at temperatures ranging from 25 to 1000°C. The results show that the compressive strength decreases with increasing temperature up to 600°C, but increases significantly at 800-1000°C under high strain rates. The study also investigated the influence of temperature and loading rate on the compressive failure behavior of the composites.

Summary: The conventional sintering process for ceramic materials requires high temperatures over 1000℃, which is energy-consuming and poses challenges in phase stability, grain boundary control, and co-firing. The cold sintering process (CSP) is an extremely low-temperature sintering technique introduced in recent years, which utilizes transient solvent in liquid phase and uniaxial pressure to achieve rapid densification of ceramics at temperatures below 400℃. CSP has attracted extensive attention due to its advantages such as low temperature and short sintering time. It has been successfully applied to sinter nearly 100 kinds of ceramics and ceramic-matrix composites, including dielectric materials, semiconductor materials, pressure-sensitive materials, and solid-state electrolyte materials.

Summary: In this study, a PZCS precursor with a Zr-C-Si main chain was successfully synthesized by copolymerization of Cp2Zr(ii) active species with (CH3)(2)Si(CH2Cl)(2). The pathways of constructing the Zr-C-Si main chain were proposed, which were different from the conventional understanding of using the Grignard reaction mechanism. The PZCS precursor exhibited high ceramic yield and has important application prospects in the field of ultra-high temperature ceramics.

Summary: This study explores the effect of carbon fiber length on the microstructure and ablation properties of silicone rubber-based ablative composites. It was found that carbon fibers longer than 3 mm can form a complete and continuous skeleton in the ceramic layer, leading to a decrease in ablation rate and back-face temperature.

Summary: The strength of the ceramic layer formed during ablation of the silicone rubber composite is closely related to its resistance to ablation. Increasing the content of graphitic carbon in the ceramic layer plays a key role in enhancing the strength of ceramic layer. In this study, series of catalytically graphitized mesophase pitch-modified silicone rubber composites with excellent ablation performance are prepared. And the average linear ablation rate of the composite is reduced to a maximum of 0.046 mm s(-1), which is 44.0% lower than that of the sample without catalyst named 5MP. XRD characterization proves that the addition of transition metal catalysts increases the content of graphitic carbon in the ceramic layers after ablation. The strength of ceramic layer of the 0.13Fe(2)O(3) reached 12.09 MPa, which is 60.3% higher than that of the 5MP. The transition metal catalyst effectively increases the content of graphitic carbon in the ceramic layers, and the strengths of the ceramic layers are significantly improved, thereby greatly improving the ablation performance of the composites.
