From the very beginning of history of making the conflicts are causing a race in designing a various kinds of weaponry froom one side and protection means from the other. Sword was set against shield, bow's arrow of cross-bow's arrow against chain armour and suit of armour.

The development of fire-arms has given the advantage of the party being in the assault and caused great changes in technology and tactics (trenches, bunkers, armoured vehicles). On the contrary the personal covers due to their weight and armou material stiffness has put the limitation on mobility of their users to the considerable degree, and their efficiency was very low.

A scientific breakthrough in that field was achieved by newly designed chemical fibres of very high strength and manufactured composites out of it. The aramid fibres of commercial name of KEVLAR® were designed in 1965 by Du Pont’a concern. Some years later TWARON® fibres were put on the market by AKZO concern. These fibres in the form of multi-ply stitched packs or composite plates appeared to be an excellent resistant material. The further progress in the above field was made when a polyethylene fibre of high degrree of crystallization and molecules packing in line of a DYNEEMA® and SPECTRA® trade names was put on the market.

Data, drawings and diagrams which are presented below were taken from our own materials and DSM's and RBR's companies information leaflets.

production details


Bulletproof helmet 93 model
This helmet has been developed by the professionals of the Military Institute of Armament Technology at Zielonka in the vicinity of Warsaw and since 1994 manufactured by BELLA company.

In a shell manufacturing process the method prepregs moulding was used. A high quality aramid fabrics of last generation KEVLAR HT as well as TWARON CT has been used for manufacturing of this helmet. The usage of T963 3300 tex fibres for manufacturing kevlar fabrics provides high parameters of safety.
Level of protection are specified by testing standard STANAG 2920:
parameter V50  = 620 m/s,

The helmet is having the ability to stop a 9mm Parabellum 8 g bullet of V0 - 350 m/s  from a distance of 5 m.

The helmet is complying with the certificates issued by the Military Institute of Armament Technology and Beschussamt Mellrichstaedt, Baeyern, Germany 
Protection Service helmet
It is the ideal helmet for Protection Service, paramilitary, penitentiary, police, prevention, and bank protection forces. The helmet is equipped with a visor made of polycarbonate and offers protection of the entire neck.
Bulletproof vests
Modern bulletproof vests include soft ballistic plates which contain Kevlar fibres and hard ballistic plates which contain ceramic material or steel in order to increase a level of ballistic protection to protect certain parts of the body such as heart, liver, groin.

In accordance with a design and protection area we can mention concealed undervests of protected area of 0,3 - 0,35 m2 approximately, outer vests of protected area of 0,5 m2 approximately and military tactical assault vests of protected area of 0,75 m2.

These vests are shown on the pictures below:
