Composite stair treads win design award
The rollers have been designed specifically to withstand the 18 tonne weight of the craft and remain unaffected by the harsh marine environment. The rollers will form part of a modular launch and recovery system that carries the Shannonclass craft from the lifeboat house to the sea. ‘Attwater are extremely proud to be involved in such an important project, working with a charitable organisation whose primary focus is saving lives,’ said sales Director Rachael Kennedy.
The UK’s Royal National Lifeboat Institution (RNLI) has called upon composite tube specialist Custom Composites to provide the rollers to help launch its Shannon Class All Weather Lifeboat.
APPLICATIONS
‘The rollers needed to remain free from stress fractures or voids, and required a manufacturer with our level of experience and quality assurance to meet their demands,’ said Andy States, general manager at Custom Composites. ‘Our composite rollers will not corrode in seawater or deform like some rubbers do under such stresses and in such demanding environments.’ APPLICATIONS

FiberSystems supplies composite pile jackets FRP manufacturer Composite Advantage has commissioned FiberSystems to supply fiber reinforced plastic (FRP) pile jackets for a waterfront application. ‘We specialize in very large FRP composite parts up to 100 ft for bridge and waterfront infrastructures,’ said Composite Advantage president Scott Reeve. ‘This was an application where the best approach was to source a pipe expert like FiberSystems.’ The New Zealand waterfront structure’s circular piers were eroding due to salt water, air and sun exposure. Concrete stay-inplace forms were used to repair the piers but corrosive conditions dictated the need for pile jackets for each of the piers. Twenty-four oz fabric knitted from carbon and glass fibers, 50 in wide by 17 ft long, was hand laid up in two sections around mandrels 18 in, 20 in, and 24 in, in diameter. Once the sleeves were custom fabricated, they were removed and split lengthwise. The outer edge of one side of the cut and the inner edge of the opposing cut were pre-sanded for easier bonding. Once installed, a special mortar was used to fill the space between the FRP jacket and the concrete pillar, creating a

Composite stair treads win design award Dura Composites, a UK supplier of fiber reinforced plastic (FRP) products, says that its Dura Slab stair treads have won an award for Innovation in Composite Design at the Composites UK awards. The structural stair treads are lightweight, meaning that the treads and landings can be easily fixed into position thanks to their sin-
gle unit construction, the company says. They feature a built-in riser for rapid installation and an in-built fall to assist with drainage and reduce pooling on stair surfaces. To ensure safety and ease of access for people with limited vision, Dura Slab Structural Stair Treads have DDA and Equality Act compliant contrasting colored nosings, and provide
a slip resistant surface, particularly when wet. Available in 65 mm or 90 mm thicknesses, Dura Slab stair treads can span up to 2.1 m clear open span, achieving 5 kN/ m2 at L/300 deflection, meaning that additional supports can be avoided in most scenarios. The 65 mm and 90 mm sizes 65
APPLICATIONS
are designed to map to the two most customary timber stair component sizes in common usage, which are 75 mm and 100 mm.

The fiber reinforced plastic used will not rot, corrode or lose color during its design life, and is suitable for installation where the footbridge or staircase is located in close
proximity to overhead power lines or electrified areas, due to its non-conductive properties. Dura Composites; www.duracomposites.com
Award for carbon concrete composite
APPLICATIONS
TU Dresden university researchers have been awarded the President of Germany’s German Future Prize for their research into carbon concrete composite. The Federal President’s Award for Technology and Innovation is reportedly one of the most important scientific prizes in Germany and was handed over by Germany’s president Joachim Gauck. Carbon concrete composite could revolutionize the construction industry by enabling resource-friendly, slender construction in the future. The composite is an economical and resource-friendly alternative to standard reinforced concrete: as carbon does not rust, carbon concrete composite structures have a much longer life expectancy. The maintenance required during this time is practically zero. Walls made from carbon concrete composite can be much thinner, and up to 80% of the concrete volume could be saved in this way in the future. The first projects have already been realized successfully using carbon fibers sup-

Composite fac¸ade built for Hague office Resin supplier Aliancys has helped to develop a composite fac¸ade solution for the construction of the new Eurojust office building in The Hague, Netherlands. The project, which required the delivery of over 700 fac¸ade panels of multiple widths and lengths ranging from 3.5 to 10 m was specified by TGM, a Dutch construction company specialized in the installation of building fac¸ade systems. This fac¸ade assembly also includes structural components, insulation to heat and moisture, ingress protection, as well as elements that provide esthetics. The composite components were made by component manufacturer Indupol through a hand lay-up process in modular molds that were adjusted to the desired shape and dimensions, using resin from ¨ fa (delivered through DisAliancys and Bu tributor Euroresins). After molding, the parts were treated with a topcoat in white color and transported to the job site for installation. 66
