The goal of a new five-year, $15 million Army contract to the University of Dayton Research Institute is to save lives.
The program, sponsored by the US Army Research Laboratory’s Survivability Branch, will use nanotechnology to address an immediate need for strong but lightweight armour for existing military vehicles, said Brian Rice, a distinguished research engineer at UDRI and manager of the Army’s survivability systems program. In later stages, the program will foster the development of next-generation composite armour for land and air vehicles, body suits, shelters, cargo containers and more.
“This is about saving lives. This is about protection systems,” Rice said. “And this is not a ground-level academic study project. We’re actually working with two Ohio companies to create a product that, if it tests out well, could show up in Iraq next year.”
Those companies are TPI Composites in Springfield, which is currently working to develop an all-composite armoured vehicle for the Army, and Armor Holdings Inc. of Fairfield, which creates and installs steel plates to armour the Army’s Humvees. “We are developing advanced composites materials to improve the performance of materials for TPI’s armoured vehicle, and we’re working with Armor Holdings to create a composite armour package that will be even stronger than existing armour, but also lighter, to reduce the top weight of the ‘up-armoured’ vehicle,” Rice said.
A number of Ohio Third Frontier awards to UDRI in recent years enabled the development of affordable carbon nanofibres and the specialized processes for their dispersion in polymer matrices to form super-strong composite materials. In addition, UDRI houses one of the top ballistics testing labs in the world for testing of armour and other materials. I
n addition to addressing weight, strength and other mechanical properties of nanocomposite materials, the survivability program will also address issues of flammability, Rice said. “Composites burn, so we’ll include flame retardants in the materials to prevent them from burning.” Improved strength, weight and flame retardance will be especially beneficial in body armour, Rice added, making it easier to wear and far more protective. “Not only will this program help save lives, it will also save limbs – in the battlefield as well as at home. Improved body armour will be affordable enough to be used by firefighters, police and other law enforcement agencies, diplomats and others who need protection.”
Beyond protection, materials advances made in the survivability program are expected to be included in a variety of other applications.
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
Web Industries, a precision formatter of flexible materials and an outsource manufacturer, has been awarded associate membership in the prestigious National Composites Centre.
Alvant says its aluminium matrix composite is proven to offer significant weight and performance benefits for rotor applications found in electric motors, flywheels, fans and turbines.
