APPLICATIONS
‘Several hundred’ orders for BMW i3 electric vehicle, which has a carbon fibre reinforced plastic (CFRP) passenger compartment and an aluminium chassis. The BMW i3 is designed for use in urban areas. It will be 250-350 kg lighter than a conventional electric car, BMW reports, and it has an approximate range of 150 km. The BMW i3 production plant in Leipzig, Germany. (Picture courtesy of BMW.)
AT A press conference in March, Norbert Reithofer, Chairman of the Board of Management of
BMW AG, reported that several hundred advance orders have been received for the BMW i3
The first pre-series BMW i3 came off the production line in January 2013. It will be on the market by the end of 2013.
The BMW i3 will require only half the time needed to produce a conventional vehicle, according to BMW, as a result of “unique production methods and a significantly lower number of assembly parts.” BMW also says it has developed timesaving repair methods especially for the CFRP components of the BMW i3. As a result, all of the accident repair costs will be similar to those of a BMW 1-Series. BMW; www.bmwgroup.com
Austin odour control project employs composite ductwork Octavia thermoplastic ECS ENVIRONMENTAL Solutions the site. Additional elements of the gases in the air stream are front end carrier has supplied an odour control the project include field joint kits, corrosive – hydrogen sulphide system based on AOC resin for a wastewater project in the city of Austin, Texas. ECS, a supplier of odour control equipment and accessories based in Belton, Texas, and resin supplier AOC, headquartered in Tennessee, worked together to create part of the city of Austin’s complex wastewater infrastructure project. The new 3.9 mile wastewater tunnel increases capacity for the downtown district. An important part of the project is an odour control system. ECS provided the odour control equipment and relied on AOC’s Vipel® resin for more than 1000 ft of glass fibre reinforced plastic ductwork and additional accessories. The ductwork ranges in size from 12 inches to 72 inches in diameter. Approximately half of the ductwork is buried below ground and had to be able to withstand thousands of pounds of high-density traffic driving over

and ammonia. There’s also sulphuric acid. Pipes built with this resin are very resistant to what goes in them: they will not easily corrode.”
ECS manufactured all of the composite ductwork using a computerised filament winder. The fibre was impregnated with AOC’s Vipel K022 corrosionresistant vinyl ester resin.
To help ease installation, ECS prefabricated and sub-assembled the duct system at its facility, then shipped it to Austin about an hour away.
“The K022 resin was the best choice for this project,” says Jeff Jones, president of ECS. “Some of

THE FRONT END of the new Skoda Octavia is made from a 60% glass fibre reinforced polyamide 6 (PA 6) compound supplied by LANXESS. The component was engineered by Faurecia Kunststoffe Automobilsysteme GmbH, Germany, using LANXESS’ Durethan DP BKV 60 H2.0 EF. “We wanted to design a totally plastic part, so that we could manage with just one injection mould and eliminate the complicated handling and shaping of sheet metal,” explains Pascal JolyPottuz, head of development for the carrier component at Faurecia. Although the polyamide has a much greater density on account of its glass fibre content, the component nevertheless is very lightweight.
ECS supplied more than 1000 ft of composite ductwork and fittings incorporating AOC’s Vipel K022 vinyl ester resin.
