AIKEN, SC, USA – (November 3, 2010) – New applications for composite armor
systems in vehicles are continuing to drive the growth of S-2 Glass® reinforcements from
AGY. S-2 Glass fibers are a significant component of the new Advanced Composites
Demonstrator vehicle from NP Aerospace Ltd. and show how the design of a protection
system can be incorporated into the structural design, reducing the overall weight of both the
protection and structural elements.
NP Aerospace Ltd. is a long-time manufacturer of body armor and security vehicles
and has significant experience in the design and implementation of composite armor systems.
NP Aerospace and AGY have a long history of development of composites for armor
applications starting with collaboration on the SNATCH / CAV100 vehicle, which has been
supplied and used in several versions in various conflicts.
“We hope to show that working with NP Aerospace we are able to provide the right
level of protection and structural performance in a vehicle to meet the demands of today’s and
tomorrow’s threats,” said Drew Walker, AGY Vice President of Sales and Marketing. “The
Advanced Composite Demonstrator illustrates how S-2 Glass fibers can provide high levels of
ballistic and blast protection while also providing a secure compartment protected against the
threat of fire, smoke and toxicity.”
With the unfortunate spread of terrorism and increased use of Improvised Explosive
Devices (IEDs), this vehicle shows how the design of a protection system can be incorporated
into the structural design with benefits in reducing the overall weight of both the protection
and structural element.
AGY’s collaboration with NP Aerospace began with the SNATCH/CAV100 vehicle
which has been used in several versions in various conflicts. “The Demonstrator’s pod and its
protection levels have been developed from the experience we has gained from our programs
with the SNATCH/CAV100 vehicles and the armoring programs for Mastiff, Ridgeback and
Wolfhound vehicles,” said NP Managing Director Roger Medwell.
The shell of the Demonstrator pod is designed using the AGY HJ1 Armor System
which is also a significant component in NP Aerospace’s CAMAC® Lightweight Composite
Armor system. This CAMAC system has been used as the core ballistic and blast protection
system on a full range of vehicles supplied by NP Aerospace and has been developed in
conjunction with AGY’s S-2 Glass fibers.
As NP Aerospace used more glass-reinforced armor to upgrade the protection level of
the new vehicles, the benefits of using high performance glass actually increased. “When we
started using high performance glass-reinforced composites these made up about half the
weight of the total solution,” said Medwell. “Now, as we upgrade our designs to meet new
threats we find we can produce a full composite based solution.”
