These energy absorbing devices are classified based on three types of energy absorption mechanisms namely material deformation, material extrusion and friction.
The material behavior is expressed by following expression (6) 4.
Also, the naturally aged material have tendency to absorb more energy as compared to annealed material.

Zeolites can divide in two types, by natural and synthesis with silica and alumina materials.
Many zeolites occur as natural minerals, but it is the synthetic varieties which are among the most widely form alternative materials such as ash, rice husk, clays and kaolin [2].

The structure of polymer adsorbents has a significant influence on the technical characteristics of sorptive materials.
Hybrid polymer– polymer materials obtained by the sol–gel method combine the distinctive properties of different groups of macromolecular compounds and are promising objects for the newest technologies.
Sorptive hybrid materials containing nitrogen and sulfur atoms in chemically active groups demonstrate sorptive activity toward a wide range of inorganic compounds including ions of noble metals [4, 5].
