Improved sandwich structured ceramic matrix composites with excellent thermal insulation

Study of the Heat Transfer Performance of Laminated Paper Honeycomb Panels

“…For example, Berkefeld et al [ 13 ] investigated the heat transfer performance of honeycomb composites made of paper honeycomb as the skeleton and aerogel as the filling material. Wang et al [ 14 ] prepared a composite honeycomb core layer with SiO 2 powder and SiC reticulated foam to effectively suppress thermal radiation. Most of the above studies focused on conduction and radiation by honeycomb sandwich panels at high temperatures, while there were few studies at room temperature.…”

Increased microwave absorption property of porous Si3N4 ceramics by loading polymer-derived SiCN for a multifunctional design

“…For instance, upon introducing MAX phases into ceramic matrix composites (CMCs), besides the retained excellent mechanical properties, the anti-irradiation, anti-ablation, and electromagnetic interference (EMI)-shielding properties also effectively improved, thus fulfilling the multifunctional requirements of CMCs. [1][2][3][4][5] In a previous study, 6 a compound core material composed of reticulated SiC foam and SiO 2 powder was filled into C/SiC laminates, and the obtained sandwichstructured composite provided high strength and stiffness along with low density and, especially, lower effective thermal conductivity at high temperatures, endowing it with great application potential in thermal protection systems. In another work, 7 a multifunctional ceramic composite system has been developed on the surfaces of carbon-fiber-reinforced polymer composites to achieve simultaneous thermal protection and high EMI-shielding ability in adverse environments.…”

Experimental and Numerical Investigation of Acoustic Performance for Full-Sized SPS

“…As a result, noise reduction technology has become a research hotspot in the elds of shipping, aerospace, and transportation in recent years [4,5]. As a laminated plate, the SPS has excellent designability and advantages, such as small weight, good sound absorption, anti-vibration performance, convenient processing, and a wide application range [6][7][8][9][10]. It has been widely used in various types of equipment such as ships, aircraft, and high-speed rail [11][12][13][14][15].…”
