EMC countermeasures using Carbon Fiber Reinforced Thermoplastic (CFRTP)
with excellent electromagnetic shielding properties

The importance of electromagnetic shielding countermeasures for mobility is expanding year by year

Many electronic devices installed in mobility, including in-vehicle LANs, emit electromagnetic waves. In this situation, not only are the devices inside the vehicle mutually affected by electromagnetic waves, but they are also susceptible to the influence of electromagnetic waves emitted from outside the vehicle, which can lead to malfunctions. Of course, electromagnetic waves emitted from electronic devices inside the vehicle may also affect other devices outside the vehicle. To minimize these impacts, the importance of EMC^* countermeasures that appropriately shield electromagnetic waves is expanding year by year.
In designs incorporating EMC countermeasures (EMC design), it is necessary to identify the sources of electromagnetic waves inside the device and the parts susceptible to the influence of electromagnetic waves, and to appropriately shield the electromagnetic waves with covers, etc. Indispensable for such countermeasures are shielding materials with high electromagnetic shielding performance. In addition, because the frequency bands used differ for each device, it is also important to be able to block a wide range of frequency bands.

*EMC：Electromagnetic EMC: Electromagnetic Compatibility. The capability to function satisfactorily with sufficient countermeasures taken against both the electromagnetic waves emitted by a certain electronic device interfering with the operation of other devices, and conversely, the electronic device being affected by electromagnetic waves emitted from the outside.

Providing Carbon Fiber Reinforced Thermoplastic (CFRTP) optimal for EMC countermeasures

Millimeter wave radars and 5G devices, which are becoming increasingly popular in recent years, generally use the 20 to 90 gigahertz frequency bands. We develop and provide Carbon Fiber Reinforced Thermoplastic (CFRTP) "TORAYCA™" that exhibits high electromagnetic shielding performance in these frequency bands.
Carbon Fiber Reinforced Thermoplastic (CFRTP) based on resins is characterized by having high strength while being light weight, making it suitable as a material for mobility where both light weight and safety are required. Not only is TORAYCA™ light weight and excellent in abrasion resistance, but it also exhibits excellent electromagnetic shielding performance equal to or better than PBT plated products in each frequency band. It is also capable of handling low frequencies of 100 to 1000 megahertz.

Electromagnetic shielding performance of TORAYCA™ resin

In addition, we have a lineup of two types of pellets with different carbon fiber lengths (long fiber and short fiber), which can be used properly depending on the application. Long fiber pellets excel in strength, impact resistance, dimensional accuracy, and conductivity, while short fiber pellets excel in moldability.

For TORAYCA™, utilizing the polymer technology and knowledge and expertise regarding carbon fibers that we have cultivated over many years, we are developing products using various polymers as a matrix, not limited to our own polymers. We can propose materials according to various applications and required properties, so please feel free to contact us. We also provide technical support to smoothly advance the customer's TORAYCA™ resin introduction process.
