Carbon prepregs (CFRP / CFRTP)


CFRP stands for Carbon Fiber Reinforced Plastics. It is a composite material made of carbon fiber that has been impregnated with a thermosetting resin and formed by curing. Ten times as strong as steel but only one-fourth as heavy, it combines the advantages of metal, such as strength and stiffness, with the ability to make lightweight products. Carbon fiber reinforced plastic is used in a wide variety of industries, including aerospace and automobiles. Machine tools are often used for cutting of carbon prepreg, CFRP (CFRTP) but our ultrasonic cutter can cut the material well.

Common uses of Carbon

  • Aerospace(Fuselage)
  • Automobile(Instrument panel, Bumper, Air back, Weather strip, Ceiling material)
  • Bicycle(flame)
  • Robot(Arm)
  • Sports(Fishing rod, Racket, Golf shaft)
  • Energy(Hydrogen tank, Windmill)

Examples of cut by ultrasonic cutter

Carbon fiber cutting.

Carbon fibers are fibers composed of carbon.
Blade can cut carbon fiber into each one without being caught by the fiber.


Carbon prepregs cutting.

Carbon prepreg is carbon fiber that has been impregnated with resin. It is used as an intermediate material for a wide variety of applications, including aircraft, automobiles and infrastructure.


Un-cured carbon prepreg 12.41mm can easily be cut in vertical and diagonal directions.

Carbon Fiber Reinforced Thermo-Plastics cutting.

CFRTP(Carbon Fiber Reinforced Thermo-Plastics)is also called thermoplastic CFRP, is a composite cured-formed using thermoplastic resin instead of thermosetting resin as the impregnating material.
