In most of bullet proof vests in order to reduce the residual energy of the bullet hits & finally reducing ingeries,various types of shock absorber foams with different thichnesses are used.
Identifying types of foams & choosing the suitable one causes increasd efficiency of this equipment.regarding this issue with the importance of those materials,in this paper we have introduced a variety of shook absorbing foams.
The foam like ZHPLY PORT,POLYOLEFINS,POLIVINLY CHLORIDE, POLYSTYRENE, EPOXY & FOAM RUBBER are investigated.POLYURETHANE FOAMS,BUTADINE RUBBER & POLYETHYLENE KRASLYNK DUE to excellent mechanical properties & especially vulnerable too,have the potential for use in bullet proof vests.
KRASLYNK POLYETHYLENE FOAMS DUE to the possibility of primary raw materiials in the country & the relatively low cost of the process are suitable for use in bullet proof vests.
