About bullet-proof jacket:

• Ballistic protection involves protection of the wearer‘s body and eyes against projectiles and fragments of various shapes, size and impact velocity.
• The projectiles are a part of ammunition shot through weapons such as pistols, revolvers and rifles.
• Ballistic protection equipments have been used for ages, the earliest form of protection was metallic suit.
• The ballistic protection equipments evolved from metallic to natural fibre fabric (layers of silk).
• With the advent of synthetic fibres, all the ballistic protection equipment was made using synthetic fibres like
• Aromatic polyamide (Aramid),
• Ultra High Modulus Polyethylene (UHMPE) and
• P - phenylene-2, 6-benzobisoxazole (PBO).
• The bullet-proof jackets protect the holder by driving away the kinetic energy of the bullet into the equipment layers by deformation of the cloth layer cutting across yarns. For e.g. when a bullet strikes a woven fabric a shock wave or strain wave is initiated in the fabric, which spreads all the way through its yarns. The first and foremost impacted yarns intermingle with other yarns by means of couplings at the cross over points of the fabrics. The strain wave can thus be hard-pressed over a large number of yarns. The upbeat effect of this mechanism is that the force will be absorbed over a large region. The pace of the strain wave dissipation of energy would depend upon the modulus of the component of the fabric

Product characteristics:

• Each jacket weighs about 5 kilograms and is expected to have the following properties:
• Light weight
• Comfortable to wear
• Facilitate body movement
• Ability to spread the projectile energy efficiently
• Each jacket has about 0.6 square meters of non-woven material weighing around 750 GSM.
• Bulk of the jacket is made from woven material as the combination of weave and the fibre characteristics influence the energy absorption characteristics of bullet-proof jacket.

Raw materials:

• The bullet-proof jackets are made from Aramid, Nylon 66, UHMPE, Carbon fibres or PBO.
• With the advent of synthetic fibres, all the ballistic protection equipment was made using synthetic fibres like
• Aromatic polyamide (Aramid),
• Ultra High Modulus Polyethylene (UHMPE) and
• P - phenylene-2, 6-benzobisoxazole (PBO).
