Mitsubishi Rayon reduces half the time required for molding carbon fiber prepreg, targeting auto applications
Mitsubishi Rayon announced on May 14th that the company commercially developed and started the sales of a rapidly hardened tough carbon fiber prepreg (Tough-Qure) from April. It not only reduced the required molding time by half but also improved toughness compared with conventional products. It takes about five minutes to harden the prepreg in stamping at 140 degrees C. The company is cultivating the market for alternative use of the conventional prepregs as well as automotive and other industrial machinery application areas. The adoption of the CFRP has been difficult because it requires longer time to mold.
For instance, the molding time of the new prepreg, for sheet trapping of golf shafts was reduced to 30 minutes from one hour under an ordinary 130 degrees C hardening conditions. It could cut half the molding time to 5 minutes from 10 minutes to stamp automotive parts under ordinary 140 degrees C environment.

Kyoto University, City of Kyoto, and VMs worked together to trial-manufacture BNF made vehicles, to examine the material which is 80% lighter but eight times stronger than steel
An industrial-academic-and government project for commercially developed next-generation Bio-Nano-Fiber (BNF) material is lighter and stronger than steel. The Kyoto University, City of Kyoto and other leading automakers will start using this material. The project targets to apply the BNF to automobiles for weight-reduction and improve fuel economy. First starting with the Research Institute for Sustainable Humanosphere, Kyoto University, the Kyoto Municipal Industrial R...

...vehicles” it features 16% lighter weight and 40% less torque loss compared with a conventional driveshaft. This driveshaft should contribute saving fuel consumption of RWD systems used for mainly high-end models. NTN will market the products to high-end car models in Europe and Japan.
The new product is comprised from two slide type cross groove constant velocity joints with ball grooves, slidable in an axial direction, is slanted into a reversed direction each other, and a hollow shaft that connects the space. The CJVs introduced smaller size balls compared with before. Increasing the number of balls to ten from the conventional six, the company has designed the outer wheel radius 9% smaller for weight- and size-reduction. It has achieved the durability of the new product by increasing several ball units.

The Carbonization process used to create carbon fiber is called pyrolysis, which uses nitrogen gas and heat as a catalyst to increase the vibrational energy of atoms. The pyrolysis breaks the bonds between carbon atoms and nitrogen atoms as well as the bonds between carbon atoms and oxygen atoms. As a result, the polymer structures formed during cross-links stabilization is converted into hexagonal carbon structures. Non carbon atoms such as oxygen, and nitrogen are removed as gas through the atmosphere. The final carbon content is over 90 % after carbonization and the temperature range of carbonization is from 900 to 1600 °C in an inert atmosphere. Heat treatment, optimum tension, completion of the reactions, and keep the molecular orientation of the precursor fiber are vital variables to produce a crystalline structure aligned more perfectly and improve the tensile strength of the
The raw Carbon Nanotubes recovered from this process can be directly incorporated in composites or rubber tires which increases the tensile strength and that is a direct application (NAIR & (IN), 2012)
When you’re to look upon the Bizzarrini BZ-2001, you’d see that there are no bounds to the imagination of Italian car stylists. The BZ-2001 is the work of Giotto Bizzarrini whose portfolio includes many past exotic cars. Right now, the BZ-2001 rides on the tubular chassis of a Ferrari Testarossa, and is powered by the Ferrari’s 380-horsepower flat-12-cylinder engine. But true to past Bizzarrini designs, plans are afoot to switch to American small-block V-8 power, and to discard the Ferrari’s frame for a chassis built solely of carbon fiber. With more power and less weight than the car has now, performance should be phenomenal.
The 2015 Nissan 370z Roadster near Seattle offers the perfect amount of performance to improve your next driving experience. The 370z is powered by a 332-horsepower 3.7-liter V6 engine. The engine features a variable valve and event lift technology that continuously tunes valve timing for quicker response and fuel efficiency. With a short wheelbase the 370z offers incredible maneuverability. You can stop easier in the 370z thanks to front rotors and 4-piston front calipers. The 370z Roadster offers lighter and quicker wheels in the RAYS forged alloy wheels. The carbon fiber composite driveshaft helps the engine rev quicker.

From the literal meaning, with RWD, the rear wheels drive the vehicle. RWD appear with the invention of automobiles. Before 1950s the RWD are the most common way for cars, like the well-known VW Beetle and Ford Model T. Thereafter with popularizing of FWD and 4WD, the proportion of RWD vehicles decreased dramatically. Currently, only trucks, sports cars and luxury cars are still based on RWD. FWD, which means front wheels drive, are more popular now because it’s cheaper than RWD.
They have designed their supercharger to deliver gains that are both broad and useable. This makes it a perfect addition to either a street car or a track car. They have a demonstrated gain of 100 percent across the powerband on several applications. Their research and develop department is always busy creating leading edge products for the street and the track.
The best model of motor vehicle is the Cadillac because it is characterized by advanced technological model enhancing the motor vehicle’s efficiency. This advanced technology makes the Cadillac a classic model of motor vehicle. The anti-locking brakes of this vehicle enable the wheels to co-ordinate well in order to give the vehicle stability. There is also a sensor that is installed at each wheel of the Cadillac. The work of this sensor is to gauge the pressure exerted by the brakes. This vehicle’s pressure is subject to the capability of the system to produce heat. The sensor and the anti-locking system serve to maintain wheel balancing.
Composites do most of the things metals can do in a bike frame. Although, often the way you go about building with composites is different than if using metals. With composite construction a mold has to be built to form the required shape and then the fibers and resin are held in the mold to harden. With metal tubing construction, off the shelf tubes a...
Carbon-fiber-reinforced-polymer (CFRP) is a composite polymer made up of carbon fibers and a binding polymer. The binding polymer can be a thermoset resin or thermoplastic polymer(s). Examples of thermoplastic polymers that can bind with carbon fiber to make CFRP are polyester, nylon, or vinyl ester. A thermoset resin that can combine with the carbon fiber to make CFRP is epoxy. The combination of the carbon fibers and a thermoset resin or thermoplastic polymer producing CFRP results in a light weight fiber-reinforced plastic that is tremendously strong. Depending on the binding polymer, CFPRs have a wide range of applications and are used when a light weight material with high rigidity and strength are required.

In the quality assurance of machine components the so-called finishing and super-finishing processes have important roles. During recent years, the post-machining cold forming methods such as burnishing, shot peening, etc., have occupied a very important place in industry, because they are reported to induce compressive residual stresses on the work piece surface, which in turn, results in improvement of tribological properties such as wear resistance, fatigue life, corrosion resistance, etc.

It is clear that the US consumption of polluting substances like lead, platinum and rubber has dropped due to improvements in the environmental friendliness of auto manufacturing, since these materials have been in use for cars since the 1950s. By replacing materials with those of a lower density has also made an important impact on fuel economy. Studies show that making 10% reduction in mass yields 5% improvement in fuel economy. Indeed, the US automakers in the last 25 years have responded to the government regulations Corporate Average Fuel Economy by changing materials to lighter ones like aluminum and plastics. Newer developments using other components like Magnesium, polymer composites, and ceramics also are helping to make further improvements to fuel
