Explosion Reduction and Force Protection

Explosion Reduction and Force Protection

Security of facilities, domestic or international, is of cardinal importance to the owners. Problems arise when increasing to security to a facility; the increase would obstruct its ability for business, or give an impression of aggression to the public.

Traditional checkpoints along the perimeter or entrances of facilities are used to control or limit access. But the problem is variability in the need of these checkpoints for different threats. If the threat level is high, a larger standoff or cleared distance around the structure might be desired from main structures in facility. But the increased standoff does not influence the danger to the occupants of the checkpoint. Likewise, the lower threat levels may reduce the need for maintaining any standoff all together.

So the now the problem facing engineers is the need to protect occupants of these checkpoints and still have variability for threat levels; one solution would be a maneuverable structure. The structure would need to provide protection from blast and fragmentation, while still having the ability of being relatively mobile. This would reduce the need for hardened checkpoints.

In addition, larger maneuverable structures could be built by linking components forming barracks, temporary hospitals, and command posts throughout all branches of service. The design of the maneuverable structure must be evaluated to determine its material efficiency, cost, and performance.

Such structures need to be able to resist a variety of blast and fragmentation threats. Due to this, fiber reinforced polymer (FRP) CTech-LLC® composites were thought to be ideal candidates for maneuverable structures with previous research showing them to have high-strength-to-weight ratio.

Fiber-reinforced polymer CTech-LLC® systems have advantages of being relatively flexible, which act as an absorption mechanism from imparted blast loads. CTech-LLC® systems are used to perform:

  • blast stiffening  of existing structures
  • protect structural members from near-proximity blasts with minimal standoff distances
  •  protect cables from various threats
  • forced entry and ballistic resistance system for brick walls
  • protection against firearms
