In order to make the car more outstanding environmental performance, Brazilian scientists are dedicated to extracting fiber from fruits, developing fruit nano-cellulose reinforced materials, and manufacturing automobile bodies. Lamborghini's new LP700-4 Aventador model uses a single body made of carbon fiber composite material.

With the goal of advancing car weight reduction, reduction, and fuel economy, Ford Motor Co., Ltd. gained inspiration from the foam porous structure of chocolate bars and manufactured honeycomb structural MuCell lightweight plastic parts by injecting air bubbles into the production process.

The MuCell material injects air bubbles into the plastic forming process to form a porous honeycomb structure at the microscopic level. The special structure of MuCell material on the one hand reduces the density and reduces the amount of material used. On the other hand, it maintains a certain strength and the integrity of the components is not compromised.

The new MuCell material has many advantages. In addition to maintaining strength and reducing density, the pressure required to form the mold is significantly reduced, resulting in a 33% reduction in man-hours compared to conventional processes. The above-mentioned manufacturing speed and processing efficiency are improved through new technologies, which effectively reduce energy consumption, processing emissions, and parts manufacturing costs.

In order to make the car more outstanding environmental performance, Brazilian scientists are dedicated to extracting fiber from fruits, developing fruit nano-cellulose reinforced materials, and manufacturing automobile bodies.

The cell wall of green plants consists of cellulose, which is similar to glass fibers, carbon fibers, and other material fibers. The nanocellulose fibers extracted from plants can be used in plastics and other matrix materials, so that the raw materials have better strength characteristics and durability.

The material even exceeds the strength of Kevlar synthetic fibers currently used as bulletproof vest material. Compared with the current automotive plastic materials, in addition to the higher strength and lower density, nanocellulose also has a recycling function. In contrast, both Kevlar and ordinary plastic come from non-renewable oil or natural gas resources.

The US auto parts supplier Johnson Controls has successfully developed a new rear seat system that differs from the common approach of using advanced lightweight composite materials to replace metal materials. Johnson Controls’s approach relies on advances in bonding technology. Achieve the mixed use of aluminum and steel; combined with other measures, the company successfully reduced the weight of the seatback frame by 34% for the rear seats.

Aluminum is mainly used for the upper and lower bars of the seat back frame, while the lateral load-bearing and lateral reinforcement beams are made of steel. The use of a mixture of two materials allows the seat frame to reduce weight by 30%.

In addition to replacing the lower part of the steel with aluminum, the steel back plate reduced the thickness from 0.6 mm to 0.4 mm (0.024 to 0.016 inches) and further reduced the weight by 4%. The seat adopts a modular design and can adapt well to the interior installation requirements of various models.

Teijin Co., Ltd. of Japan announced the world's first mass-produced carbon fiber reinforced plastic CFRP (Carbon Fiber Reinforced Plastic) technology.

Teijin uses thermoplastic resin instead of traditional thermosetting resin as the matrix of carbon fiber composite material. Based on this, three kinds of intermediate materials (IntermediateMaterial) are derived. Using stamping and injection molding processes respectively, the processing time is significantly shortened and can be within 60 seconds. Stamping the cabin frame. At the same time, the company also developed CFRP material welding and bonding technology. To verify the newly developed technology, Teijin used CFRP materials to prototype a small electric vehicle body.

The body consists of more than 20 press-formed and injection-molded parts, with a total weight of 47 kg.

After the body was built, Teijin purchased products such as motors, suspensions, and tires from the market to form a complete vehicle and use it for driving tests. The maximum speed of the vehicle is 60 km/h and the cruise journey is 100 km.
