According to the respective limitation and characteristic of gel fire prevention materials and foam fire prevention materials, a new thinking of foamed gel coal fire prevention materials is put forward creatively.
For large coal fire zones, the new fire prevention materials (Foamed Gel) have a broad application prospect.
New fire prevention materials are developed by collages and institutes, and the foamed gel is the most representative.
Summary The foamed gel fire prevention materials that fully combined the advantages of foam fire prevention materials and gel fire prevention materials have the characteristic of strong stability, prefect fire performance and excellent sealing performance.

Nowadays, the inventory control is inclined to adopt different policies to different materials [1].
In the aircraft manufacturing industry, many materials can only be procured from one company and some materials are imported abroad, so it is more common that material can not be procured easily.
The Civil aircraft is manufactured in single-piece, so some materials are used only in one aircraft.

Intelligent Matching of Cutting Tools with Workpiece Materials J.
Those cutting tools, which materials have greatly chemical affinity with workpiece materials, are scarely selected.
Those ceramic tools which materials contain aluminum and Ti elements, i.e.
After matching in material performance between cutting tool and workpiece materials, geometry angle needs to be considered.

In this paper, Continuous Basalt Fiber (CBF) was used as the raw materials, and then woven by the Digital sample looms.
The CBF, would be bound to play a significant role in future of fire-retardant materials and high-temperature composite materials, exhibited excellent flame resistance and heat resistance.
Results and Discussion 3.1 Results 3.1.1 Limiting oxygen index test The limiting oxygen index(LOI), reflected the burning behavior of the materials, is the minimum oxygen content to support combustion of materials in nitrogen-oxygen mixed gas, and abbreviated as LOI.
Therefore, Basalt fibers would have broad prospects in the area of flame-retardant composite materials.
