Formed in 1992, Surface Transforms originated out of the Advanced Materials group of ICI when four former employees bought the intellectual property rights to the materials technology. Initially, and for quite a lengthy period nf time afterwards, it served as a research and development company. Initial projects were funded programs that looked at various applications including aerospace and railway carriage braking. It even started to become involved in Formula One. However, the timing was unfortunate because the company initiated the project just at the time when the FIA, the sport's governing body, was In the process of banning carbon ceramics on Grand Prix cars. Surface Transforms duly refocused its efforts on fitting its brakes to high-performance road cars. As a result, Surface Transform's System ST brakes can now be found on the Koenigsegg supercar as an option on the CCX. which was launched at last year's Geneva Show and on the CCGT that was launched at this year's show, the $600,00 Ascari AIQ, and a new supercar from Weber Sportcars. Altogether, System ST is now fitted to more than \b different car platforms. Surface Transforms is also working in partnership with StopTech, a California based leader in balanced brake upgrades for production cars and production-based racecars, to promote the adoption of carbon ceramic brakes on high-performance cars in the U.S. market. An annual supply contract has not yet been signed, yet both companies forecast that in the aftermarket between 50 and 100 car sets will be required in the nexl 12 months. StopTech has placed the first production order and will soon be offering the System ST ceramic brake disc on selected vehicle offerings. "Carbon ceramic brake technology was really brought to the market by three cars that were launched, utilizing the technology at a similar time-the Ferrari Enzo, Porsche Carrera GT and the Mercedes McLaren SLR-and Surface Transforms had the appropriate technology." says Antoni Sznerch, Surface Transforms' business development director. Unlike carbon-carbon brakes, carbon ceramics do not need to be hot to work, they work optimally from cold while offering significant weight saving over traditional iron rotors. They also have negligible wear in normal use. "The fundamental difference between the brake discs that are fitted to these three cars and Surface Transform's technology is that they are manufactured using discontinuous carbon fiber, where our discs are made of continuous carbon fiber. This means that their mechanical integrity should be superior because the strength of carbon lies in the direction and length of the fiber." • A How do you stop this Koenigsegg CCX?

"We use what could be called a traditional nought/90 fiber orientation. However, our raw material is carbon fiber precursor which has 30% elongation in the fiber before it will break whereas carbon fiber only has 2%, This 30% elongation allows us to needle the fibers together so that we not only have the nought/90 orientation but also have the fiber in tbe Z direction through the material bundle and that is what binds the fibers together.
