COMPOSITES FOR ARMOUR SOLUTIONS
2
What is Armour
Role of Armour is to protect a person, structure or device
Achieved by absorbing kinetic energy of the projectile
Energy may dominantly be absorbed by plastic deformation and/or fracture
processes
Fragments as a result of fracture process should not cause damage to what is
being protected and should be arrested by another layer at the back
Armour plate may have to fulfill two roles: a protective role and structural role
Both roles can be fulfilled by having sufficient strength at high strain rate and
appropriate thickness to provide both protection and structural requirements
of the Platform (Integral Armour /Structural Armour)
Technical Requirements
Protection requirements are threat driven
Very significant analysis is done to identify threat probability
and threat development under different scenario.
However, threats may be considered to be of some basic fundamental
types
‐Impact
Kinetic Energy, Chemical Energy (“Shaped Charge”)
‐Blast
* Mines (AP, AT, Influence), HESH
‐Combined blast and impact
Specific weapons, entrained debris (Claymore mines)
