The latest application of composites in automobiles

the key to improving fuel efficiency is to reduce weight. Therefore, original equipment manufacturers (OEMs) now pay more attention to the lightweight advantage of composites, while its price advantage over steel and aluminum is second. The government's demand for high mileage and low emission vehicles has led automakers to innovate and seek more expensive materials, such as carbon fiber composites and nanocomposites, to achieve the goal of lightweight

material suppliers are very optimistic about the application of composite materials in the automotive industry. Cedric ball of Ashland high performance materials believes that the automotive industry is in a major period of transformation to a new generation of vehicles. "Under the dual pressure of improving fuel economy and reducing production costs, we are in the 'perfect storm' of market pressure and industry trends. Therefore, composite materials are far more attractive to automotive manufacturers than before."

Ball is the seminar director of the 2010 automotive composites Symposium and Exhibition (acce, September, Michigan, USA) hosted by the American Society of plastic Engineers (SPA). This year, the theme of acce is "Composites: creating new cars". The symposium has been held for nine times, which is the tenth. It is an important forum in the field of automotive composites, attracting many exhibitors, speakers and participants from all over the world

creig Bowland, the technical director and researcher of the long fiber thermoplastic Department of PPG Industrial Company, is responsible for the formulation of the technical agenda of acce. He believes that the demand for composite materials in the automotive industry has surpassed the past. "The slow pace of automobile manufacturing and the urgent demand for energy-efficient vehicles mean that composites have become the real solution."

electric vehicle

many people regard hybrid electric vehicle as a good way to get rid of dependence on fuel and reduce emissions. At the North American International Auto Show held in Detroit in January, about 20 electric vehicles were on display. Lightweight materials are essential to reduce the increased battery weight of hybrid vehicles. But can electric energy be stored in composites? Royal College London says this is not impossible

researchers at Royal College and their European partners (including Volvo Group) have developed a carbon fiber composite prototype that can change the appearance of hybrid cars. This patented material can store and release electric energy. It is not only durable but also light in weight. It can be widely used in all kinds of wood, such as plywood, particleboard, medium density fiberboard and other wood plates, for the manufacture of structural parts and body panels. The researchers said that the car made of this material itself can be used as a battery. It is said that this material can store and release a lot of energy, and the speed is much faster than traditional batteries. There is no chemical reaction in the charging process, so the battery made of it will not age with time

automatic processing of composites

mag industrial automation system company launched its breakthrough automotive composite technology, "which combines the cost and productivity requirements of the automotive industry and the engineering characteristics of oriented fiber structures used in the aerospace industry". Its new continuous foaming line uses continuous fiber thermoplastic and thermosetting prepregs to produce thin-walled structural engineering parts, which are% lighter than steel parts, but their strength is twice that of SMC

According to MAG, the focus is on optimizing the performance of low-cost reinforcement materials, such as E-glass fiber, although carbon fiber and mixed prepreg can also be processed by this machine. It is said that the continuous fiber prepreg developed by the company has a much lower deformation coefficient than SMC, and the distribution and orientation of reinforcing fibers are more uniform than that of chopped fibers. The production line can cut reinforcement materials according to the design requirements of components, regardless of whether the processing is structural components or the whole underbody of multi-component

in order to meet the needs of different production scales, continuous latifying line adopts a modular design, and each module can handle two rolls of 2.4m wide prepreg. The system can lay materials with different widths on one part. One module can process full width materials while the other can lay narrow width materials. Cutting and splicing can ensure continuous operation and the laying of cross layers, so as to strengthen the transition area, such as the stiffener across the car on the floor. Modules for placing sandwich materials in sandwich structures are also being developed
