New composite brake disc

Almost brake discs are made ​​by cast iron. Recently,a lot of racing and other high performance vehicles have been equipped with composite design brake disc. This design in the surface of the brake disc using the hybrid composite (carbon fiber – ceramic), while the remaining part of the use of aluminum or cast.
The Brembo launched a new brake disc: the complex cast floating brake discs made of cast iron and aluminum. The new brake disc has a lot of advantages: lighter weight (15-20%) reduced the driving comfort higher, better corrosion resistance, abrasion resistance and higher braking performance.
Complex casting floating brake discs optimize brake system performance SUV from the most basic to the sporty the strongest sports cars and commercial vehicles vehicles.
Complex cast floating brake disc with a cast iron braking surface and aluminum caps Ministry, this design is ideally combines the lightweight characteristics of heat resistance advantages of cast iron and aluminum. Innovative technology so that one member can be manufactured using two materials, in working condition, the brake disc as an integral member at a low temperature effective operation, while at high temperatures, maximum performance, and deformation may occur, then the system dynamic disk will be run as a floating part.
Cast brake discs lighter complex to meet the demand for lightweight braking system, brake response limit work state, allowing a more sensitive and has better performance of high-temperature fatigue resistance. Therefore, the probability of instantaneous thermal deformation and permanent thermal deformation event, appears will be significantly reduced. The the instantaneous deformation events usually occur when the brake pedal is depressed, the brake disc may have a fever, however, the the permanent brake rotor deformation is the main reason for the vibrations of the vehicle during braking.
The cast iron has the best thermal performance, the degree of deformation is low, and good thermal conduction properties, while having good technological properties, such as castability and high machining performance. It also has many other advantages, such as good damping performance. On the other hand, aluminum has the advantages of light weight, the density is only cast iron 2? Times, so that, depending on the application of complex casting the brakes disc than one brake disc light 15-20%.
This is a major step forward, because taking into account the weight reduction will significantly improve ride comfort and driving accuracy, even if the vehicle weight reduced to 1 kg car manufacturers also have extraordinary significance in the removal of “non- hanging “especially after the weight.
Unlike integral braking disc complex casting the brake disc has a symmetrical braking surface, in the embodiment during braking disc surface temperature distribution is more uniform, which means release the residual degree of deformation of the brake after a significantly lower (70% reduction) . In addition, the complex casting design means that the brake ring, having the characteristics of the natural materials free expansion under heat. This effectively improves the performance of the floating disk. But the floating components do not need too many parts.
Given two complex casting material has many excellent characteristics, this performance brake disc successfully reduces the material of the brake disc in the brake is released and the brake pad wear.
