Composite protection pod dampens and absorbs incoming blast waves on the Ocelot Light Protected Patrol Vehicle (LPPV)

AGY : 03 April, 2011  (Application Story)
Composite protection pod dampens and absorbs incoming blast waves on the Ocelot Light Protected Patrol Vehicle (LPPV)
Designed to meet the UK Ministry of Defence’s (MoD’s) LPPV program requirements, the Ocelot provides unprecedented levels of blast protection for a vehicle its size. FPE has been contracted by the UK MoD for the production of the Ocelot and has received an initial order for 200 vehicles to begin delivery in 2011 for deployment in the most hostile of operational environments.

Force Protection Europe is a subsidiary of Force Protection Industries, a leading provider of survivability solutions, and whose MPRAP vehicles provide high levels of blast protection.

According to Drew Walker, Vice President of Sales and Marketing at AGY, “The MoD’s LPPV vehicle program requires a significant level of armoring to protect against ballistic, mine and roadside bomb threats and this is achieved in part through the use of our S-2 Glass reinforcing fibres. S-2 Glass fibres are a high performance fibreglass offering significant improvements in performance over traditional E-Glass fibres. The composite can be built to provide structure and has the ability to handle the mechanical aspects of an advanced vehicle design. In this particular case, it also offers significant protection for both blast and ballistic testing at weights much lower than traditional metallic materials.”

“The whole crew compartment is manufactured of the S-2 Glass composite,” said Walker. “This composite protection pod dampens and absorbs incoming blast waves much better than metallic crew compartments.”

In traditional light armoured vehicles, a metallic skin is backed by a composite spall liner to mitigate the behind-armor effects in an over-match situation. “In the Ocelot, because the hull is composite,” explained Walker, “There is a greatly reduced spall liner requirement, further reducing weight. The choice of materials in the composite shell also affords a high level of protection against fire, smoke and toxicity that is not inherent in many of the more expensive high performance fibres.”

“Ocelot is a step change in protected mobility for this weight and class of vehicle and I am confident that it will be used to great effect in Afghanistan and any future operations,” said David Hind, Managing Director, Force Protection Europe. “By working with companies like AGY, it enables us to offer innovative and superior survivability technologies to our customers.”

AGY’s S-2 Glass fibres have found increasing application in composite armour systems in recent years in the drive to make armored vehicles light while meeting the demand for protection from new and evolving threats.
