One of the most interesting materials is ceramic because of its hardness, of its relatively small density and of the reduction of collateral damages, and the other one of the most interesting materials is aluminum because of its small density and ductility.
Clear correlations are observed between the projection capability and the confinement materials.
In this paper, we shall compare results obtained by varying the materials of the confinement plates made of steel, ceramics, aluminum and copper.
MATERIALS USED One steel alloys, one aluminum, one copper and one ceramic have been selected to investigate the behavior of the RACs.
Table 1 lists these materials their properties.

Emergency distribution and emergency supply chain Distribution of emergency materials is an important link of emergency logistics, and emergency supply chain management is the highest level of emergency logistics management (Sheu, 2007).
Except for reasons beyond control such as traffic interruption and communication interruption, unreasonable emergency materials distribution primarily performs as that: some affected points are superfluous of emergency materials; while some are lack of emergency materials which interrupt the operation of relevant rescue activities.
In addition, owing to the unbalanced materials distribution, some kinds of materials are delivered repeated, while some are relative insufficient.
Through the information released by the emergency materials information platform, this study summarizes part of demands of emergency medical textiles.

In the previous research, the recycled materials exhibited excellent mechanical properties.
To improve the mechanical properties of recycled materials fabricated by solid-state process, recycled materials were extruded repeately in this work, and the effect of extruding times on distribution of oxides and mechanical properties of recycled material was investigated.
