The European Commission funded a research project, C 3 HARME, under the NMP-19-2015 call of Framework Programmes for Research and Technological Development in 2016-2020 for the design, manufacturing and testing of a new class of ultra-refractory ceramic matrix composites reinforced with silicon carbide fibers and Carbon fibers suitable for applications in severe aerospace environments.
The UHTC composites show higher mechanical properties like Tensile strength, Young's modulus, hardness, flexural strength, and fracture toughness at high temperatures as compared to monolithic UHTCs. The high sintering temperature and pressure result in high residual stress in the composites, which can be released at high temperatures.

Since SiC–SiC composites are generally sought for in high temperature applications, their oxidation resistance is of high importance. The oxidation mechanism for SiC–SiC composites vary depending on the temperature range, with operation in the higher temperature range (>1000 °C) being more beneficial than at lower temperatures (<1000 °C).
Along with the high temperature properties, this thermoset polymer type must be processed at very high temperatures and relative pressure to produce optimum characteristics. With prepreg materials, 600 °F (316 °C) to 650 °F (343 °C) temperatures and 200 psi (1,379 kPa) pressures are required. The entire cure profiles are inherently long as ...
G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. [1] It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures. [2] [3] It is manufactured in flat sheets, most often a few millimeters thick.
[citation needed] SiC–SiC matrix composites are a high-temperature ceramic matrix processed from preceramic polymers (polymeric SiC precursors) to infiltrate a fibrous preform to create a SiC matrix. [6] Several other types of curing agents are also used in the advanced composite industry.
Various matrices and fibre combination can be used to produce different composite properties. (SiC, C, Si 3 N 4, BN, B 4 C, ZrC, etc.). There is very little damage to fibres and to the geometry of the preform due to low infiltration temperature and pressures. [3] This process gives considerable flexibility in selecting fibers and matrices.
