FFWD F6R MATTE BLACK
產品環境效益說明
FFWD DARCtm technology is short for Double Arc which refers to the profile of the rim. The revolutionary DARCTM profile improves aerodynamics dramatically by reducing the drag. Air has the characteristic to stick to its surface and by cre柑ting a negative arc section the air will be compressed more at the positive section. This will increase the pressure just like on the topside of an airfoil. 1.CARBON :We use High-Tensile TC-35 carbon for the majority of the lay-up. This gives the rim a very high strength with sufficient stiffness to cope with hard application of the wheels. So, rather than use a stiffer, but more brittle carbon type, we chose durability over ultimate stiffness. In some lay-ups we add some higher modulus sheets to increase stiffness locally.We actually use multiple layers of different types of carbon. Only the outer layer is made from a 3K weave. Underneath this layer are layers of UDF (Uni-Directional Fiber) sheets. A mixture of different angles to resemble a uniform material. Because carbon fiber can handle tension very wwell, we have to mix up the layers to make the rim stiff and strong enough. Pressure is not a great feature of a fiber. Just think of a string being pushed. 2.ECOM :All rims are molded with a process we call Ecomtm (Equal Compression). This means that the rims are molded with a custom-made air bag that has the inner shape of the rim. This makes sure that the pressure/compression is equal on the entire inner surface of the rim. Result is a practically void less rim section and a smooth wall on the inside of the rim. Without voids, the carbon sheets are completely fused into one system. The rim structure is much better and you can make the rim lighter and stronger.
