The world's first thermoplastic composite automotive brake pedal successfully mass-produced

    Recently, Times New Material Bogo launched the world’s first mass-produced thermoplastic composite automotive brake pedal. This innovative brake pedal adopts a unique design scheme, mixing three different composite materials, and introducing The distinctive production process meets the safety and economic requirements of automobile factories.

    The brake pedal, also known as the "foot brake", is more closely related to the safety of the car, and has higher requirements for its own strength, rigidity, and torsional load. Bogo's innovatively developed full thermoplastic composite brake pedal has a size of 350*90*60 mm. Compared with the previous design, the amount of organic board has been reduced by 33%, and the nominal wall thickness has been reduced from 3 mm to 2 mm. , The weight of this product is about half of the metal pedal, but the strength is similar to it, or even higher than the latter, which helps to enhance the driver’s driving experience.

    Bogo uses three different materials for different positions of the brake pedal. As the main load-bearing structure of the pedal, the shell structure needs to withstand a pressure of up to 3000 Newtons. At the same time, it needs to be light and thin and cost-effective. Continuous glass fiber organic board; for the part of the organic board that needs to be locally reinforced, unidirectional fiberglass tape is used, and in accordance with the requirements of the automobile manufacturer for the material strain curve under specific temperature and humidity conditions, the placement is calculated by the method of finite element analysis In addition, in order to realize the functional geometric shape in the pedal, Bogo used chopped glass fibers provided by multiple suppliers, and formed stiffeners and other auxiliary structures using a composite molding process. By mixing three different forms of glass fiber reinforced materials, Bogo has achieved precise control of fiber orientation, which not only meets the performance requirements of the brake pedal, but also avoids the waste of materials, reduces the wall thickness, and shortens the production cycle. , Reduce the cost of components.

    As early as 2008, Bogo began to use continuous fiber organic boards and chopped glass fibers to produce auto parts by overmoulding. In 2018, the thermoplastic unidirectional belt was introduced, and the production cycle was shortened, the cost was reduced, and the business volume was expanded through the innovation of the process. The annual output of the production line can reach 1 million pieces.

    Engineer Dr. Daniel Haffelin, General Manager of Bogo Global Innovation Center of Time New Material, said that as the automotive industry gradually develops in the direction of electric, the design of the brake pedal will also become more complicated due to the requirements of electrification and integration, and Time New Material Bogo will also Committed to creating more valuable automotive products and enhancing industry competitiveness.
