Norwegian scientists have come up with a smart and cheap way of bullet-proofing cars by lining the vehicles with flat tanks which, when filled with water, provide excellent protection against armed attackers.
The problem with conventional armour-plating is that metal is very heavy which increases fuel usage.
Researchers at Norway's Forsvarets Institute have found a way around this by building several large, flat, watertight tanks into the sides of car. Each tank is thin, like a domestic radiator, made from plastic or light metal, and has several energy-absorbing carbon-fibre sheets stacked inside.
When the tanks are empty the car is not bullet-proof, but when needed, the tanks are filled with water, transforming the car into a bullet-proof vehicle.
The tanks have been tested using high velocity bullets, and according to a leading international science publication, the novel armour design has now been patented.
The Institute for Advanced Composites Manufacturing Innovation (IACMI) has announced the Phase I completion of a project led by DuPont, partnering with Fibrtec and Purdue University, focused on the creation of a new carbon fibre composite manufacturing process that exhibits improved fabric formability characteristics compared to traditional woven materials.
Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
As part of its mission to address composites end-use industries, JEC Group is investing in composites showcases at key automotive events worldwide.
