Recently, the similar materials are used to do the experiment both at home and abroad, yet it can't reflect the original nature and others of rock fissure in original rock mass.
Since the similar material are made of synthetic materials，it cannot reflect the original rock nature-like fissure and mechanical properties and so on.
Laboratory model test In this experiment, collected one large size of undisturbed sample of Tertiary mudstone from one project in Nanning, Guangxi,China, which is used as materials of laboratory model test of surrounding rock in underground tunnel.

Introduction Combustion synthesis (self-propagating high temperature synthesis, SHS) is a novel technique to produce high temperature ceramic and composite materials.
The process is a highly exothermic reaction within a mixture of reactive powders in a few seconds and can allow for difficult intermetallics materials to be easily manufactured.

Since, silicon carbide material is used as a polishing material to avoid the deposit of carbon at the inner side of the flow passage and this waste heat energy is used for heating passenger cabin during winter season.
The wood is used as an insulating material to avoid the heat flow from fluid to atmosphere.
The lubricating property of the silicon is more compared to silicon carbide material.
But the thermal conductivity of silicon carbide is more compared to beryllium and silicon material.
