Ultra High Temperature

In this paper the preparation of carbon fiber reinforced ultra-high temperature ceramic matrix composites was reported. Polymer infiltration and pyrolysis process was used to prepare 2D C/TaC-SiC, C/NbC-SiC, and C/ZrC-SiC composites. The fracture strengths of all the samples were around 300MPa and toughness around 10MPa-m1/2. Standard oxyacetylene torch tests (>3000°C, 30s) showed that the minimum ablative rate of 2D C/SiC-ZrC was as low as 0.026 mm/s, much smaller than that of 2D C/SiC composites (0.088mm/s).

A critical phase in the life-cycle of a material is the transition from the development stage to that of design and industrial application. Advanced technical ceramics are currently in this phase and their future market penetration and acceptance as engineering materials critically depend on the availability of a robust set of standards for test methods which allow one to determine their mechanical and thermal properties in a reliable and reproducible way. In Europe, standardisation on continuous fibre reinforced ceramic matrix composites (CFCCs) officially started in 1989, when CEN TC 184 on Advanced Technical Ceramics was launched. The scope of TC 184 covers testing methods, and no efforts are paid to the development of material and product standards as yet. The work programme of TC 184 in the area of CFCCs, aimed at the establishment of testing methods for the generation of reliable data for design purposes, is reviewed.

SiC-Si3N4 powders and modified SiC-based ceramic matrix composites (CMCs) were fabricated using polycarbosilane (PCS), divinylbenzene (DVB) and Si3N4 filler. Si3N4 was introduced into CMCs fabricated through polymer infiltration and pyrolysis (PIP) to lower down the carbon content by in-situ carbothermal reaction, which derived from pyrolyzed PCS-DVB. The oxidation resistance and three point bending strength of modified C/SiC composites were effectively enhanced. The phase composition, microstructure of SiC-Si3N4 powders and modified C/SiC composites were investigated by XRD, SEM and TEM.
