Hybrid Carbon -Composite Wheels
영국 경주용 차량 제작사인 BAC 사는 하이브리드 탄소-복합재 휠을 공개하였다. 이 17인치크기의 혁신적인 휠은 부드러운 곡선형 모서리를 가지고 충분한 강도를 가질 수 있는 탄소복합재로 만들어진 림을 가져서 휠의 회전 무게를 낮출 수 있으며, 강성이 필요한 스포크는 알루미늄으로 그리고 다섯 쌍의 티타늄 볼트를 사용하여 휠을 자동차와 고정함으로서 강도와 경량화 효과를 얻을 수 있다. 이로 인해 일반적인 휠에 비하여 우수한 핸들링 및 성능을 가진다고 밝혔다.
BAC has revealed an upgrade to the looks of the Mono supercar, with a brand new set of hybrid carbon-composite wheels available for new and existing cars.
The new wheels typify BAC's innovative approach to new technology, and show how the company is able to take bold steps in collaboration with its suppliers and to take new developments to market.
BAC's co-founder and Design Director Ian Briggs led the design of the wheel, which was created to complement and enhance the car's looks. BAC put the performance at the forefront, as the design was led by the function of the wheel. As part of its quest to use British suppliers whenever possible, BAC has teamed up with elite performance wheel brand Dymag.
The innovative 17-inch wheels are an advanced carbon composite construction, and are made using the latest technology from Dymag. The rim, which features soft curved corners to aid strength, is made of carbon composite to lower the rotational weight of the wheel.
The spokes, where stiffness is a crucial requirement, are crafted from a solid billet of aluminium, while the wheel is secured to the car with five pairs of titanium bolts, adding further strength and lightness. With each wheel bolt weighing just 30.2g, this amounts to a 212.5g saving per wheel.
As well as adding to the dynamic and purposeful look of the Mono, the new wheels boost the car's handling and performance due to being notably lighter than the standard wheels. The total weight saving on the front axle is 23.5%, where the 7.5-inch by 17-inch wheels weigh 5.7kg each. The 9-inch-wide rear wheels each weigh 6.0kg, despite being half an inch wider than the standard rims, amounting to an overall 22.9% reduction in weight on the axle.
On a wheel with fewer spokes, the rim has to be heavier in order to take the increased load between the spokes. By using five pairs of spokes, BAC has achieved the clean look of a five-spoke rim, but with the structural and weight saving benefits of a 10-spoke wheel.
Visually, the wheels evoke the spirit of high-end sports equipment, thanks to the large graphics on the rim, which give the wheel a strong, bespoke look. The design of the wheel means that the extent of options as part of the BAC Bespoke programme can be increased. As well as choosing to colour match the spokes with the body of the car, the customer will also be able to tailor the colour of the logo and the wheel's finish.
