Thanks to the new manufacturing process developed by Nissan, the Carbon Fiber Reinforced Polymer (CFRP) material, which is widely used in aviation, aerospace and sports cars, can be more conveniently applied to mass-produced vehicles.
The production process introduced by Nissan can speed up the development of auto parts. Carbon fiber composite material (CFRP) has a small specific gravity and high strength, which can make the vehicle safer and more energy-efficient. At the same time, it can also help lower the center of gravity of the car body and bring a more sensitive and exciting driving experience to the driver.
Nissan plans to use a new process to mass-produce carbon fiber composite material (CFRP) components and promote it to more models. Compared with the traditional manufacturing process, this innovation can shorten the front-end development cycle of carbon fiber composite material (CFRP) components by half and the molding cycle by about 80%.
Although the advantages of carbon fiber are widely known, it is more expensive than other materials such as steel. Due to the difficulty in shaping, the mass production of carbon fiber composite material (CFRP) components was also affected.
Based on existing production methods, Nissan has developed the “compression resin transfer molding method.” That is, in the existing production process, the carbon fiber is forged into an appropriate shape and placed in a mold while leaving a small gap between the carbon fiber and the top of the mold, and then resin is injected into the gap and hardened and shaped.

The new technology developed by Nissan’s engineers can accurately simulate the permeability of the resin in the carbon fiber, while using an in-mold temperature sensor and a transparent mold to visualize the resin flow in the mold. After the simulation is successful, high-quality components can be developed in a shorter time.
