ACG Prepreg Used in Hydrogen-Powered Car

11 September 2009

Vehicle weight often attributes a great deal to a cars fuel efficiency, which is why Riversimple used Advanced Composites Group’s composite materials in its recent hydrogen-powered concept car.

Both the body and bonnet of this lightweight two-seater were manufactured in one-shot processes using ACG’s LTM 26ELB (extended out life, black pigmented) epoxy prepreg materials, which ACG say have the added advantage of utilising low cost tooling and manufacturing technologies.

In order to achieve the finished product, Riversimple used out-of-autoclave vacuum bagging, which was calculated as being the simplest and cheapest method. However, ACG say that these prepregs can also be press moulded and autoclave cured. Clear, fire-retarded and low smoke (DIN5510, M1 compliant) variants of this resin system are also available.

The finished product is a zero-emission car which has low running costs. Riversimple say that the estimated annual running costs, inclusive of fuel and maintenance, for urban use are approximately £2,500.

The hydrogen fuel cell powers four electric motors, one mounted at each of the wheel hubs and is capable of delivering a top speed of 50mph, travelling around 200 miles between refueling stops.
