Reproducing an enhanced and lightweight component at the same price(CFRP)

CFRP

We combine carbon fiber and resin, providing material with enhanced features, that is not possible using only a single material.

  • carbon fiber
  • +
  • resin
  • Carbon fiber reinforced plastic

PROPERTIES AND USES

CFRP is 1/5 the weight of iron and is rigid. Also, CFRP has excellent x-ray transmittance and conductive properties, drawing attention as an advanced composite material.

Making the most of these features, CFRP is gaining acceptance in a wide range of fields such as sporting goods (golf and snowboarding) and space equipment (satellites and rockets).

Properties and uses

SUGGESTED USES

  • Fishing boat
    Fishing Boat

    CFRP does not rust since it is not produced from iron. It’s reduced weight lightens the entire vessel, increasing load capacities and energy savings.

  • Medical equipment
    Medical Equipment

    CFRP, with excellent x-ray transmittance and conductivity properties, is becoming a preferred material for medical applications.

  • Auxiliary instrument
    Auxiliary instruments

    It is being adapted for use in various medical products since it is light and sturdy.

Molding methods

Sheet winding molding

This is a process where you wrap prepeg (a plastic molding compound which is impregnated sheet-like fiber with resin that is then semi cured) outside of a rolling mandrel (core metal), remove the mandrel after thermal curing to mold a pipe shaped object. This process is used to mold pipes, fishing rods and golf shafts.

Autoclave molding

Autoclave molding

Resin transfer molding

In this molding method you place reinforced fiber into a mold and pour resin, under pressure, into an airtight container. “Transferring resin” is one of the greatest methods as it does not require a pressure vessel, such as an autoclave, and does not produce any waste (bag or seals). This method has excellent dimensional stability during the molding process as it uses an actual mold.

Resin Transfer Molding

Press molding

This is a method in which a 2 part mold is installed into a press, which is then molded with pressure and heat for plasticity and/or deformation. This method allows the use of a cassette type mold which is suitable for low volume production runs, such as prototypes.

Press molding

Hand lay-up molding

This is a type of FRP (Fiber Reinforced Plastic) molding. Hand molding after laminating soft sheet like FRB (before curing) impregnated fiber with resin on a mold with a brush or roller. This method relies heavily on hand work and is suitable for larger size products reinforced by continuous fiber. Perfect for molding a boat or even a bathtub.
