Properties & Features of  Futaba's CFRP PLATE

Futaba's CFRP PLATE is a new material offering the properties of CFRP - traditionally associated with conventional carbon sheet applications - while turning common-sense conceptions of the material upside down.

Material property

As a metal cutting manufacturer, we have thoroughly investigated

the material to verify that it is capable of replacing metals.


  • Both stronger and lighter than aluminum (half the specific gravity of aluminum or less) 

  • High impact absorbing capacity

  • Low thermal expansion coefficient

  • Rust and corrosion resistant

Comparison of physical properties and strength

Replacing aluminum alloy (A5052) with Futaba's CFRP PLATE can reduce weight by 50%.

Despite its light weight, it offers tensile strength approximately 1.3 times that of aluminum alloy.

Futaba's CFRP PLATE can be compared to metals in various aspects.

For more information, please download the physical properties document.


The porosity of Futaba's CFRP PLATE does not exceed 1 %.

​X-ray images show no areas containing defects, making the material safe.

Key points

Comparison of processability to that of ordinary CFRP


  • ​Hole drilling is possible in the tolerance zone equivalent to H7

  • Surface roughness of less than Ra 1.0 achievable as it can be ground. 

  • Using an end mill allows clean grooving on the sides free of burrs


Drilling and end-milling were performed under identical cutting conditions.

The two materials differ significantly in processability, including burr formation.

Chemical and weather resistance test results

No effects on strength were identified following immersion in various chemicals and after UV irradiation.

In contrast to iron and other metals, no signs of rusting or corrosion were identified.

Effect of immersion in chemicals on strength and weight

<Chemicals used>

Salt water: 5 % salt concentration

Lubricating oil: Super Mulpus mineral oil

Grinding fluid: Hocut 702 triethanolamine

​Even 1,000 hours of immersion in various chemicals caused no effects on strength and weight!
