We combine carbon fiber and resin, providing material with enhanced features, that is not possible using only a single material.
PROPERTIES AND USES
CFRP is 1/4 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).
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.
CFRP, with excellent x-ray transmittance and conductivity properties, is becoming a preferred material for medical applications.
It is being adapted for use in various medical products since it is light and sturdy.
Epoxy, Unsaturated Polyester, Vinyl Ester, Phenol, etc.
Acrylic, Polycarbonate, Nylon, PPS, PEEK, etc.

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.
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.
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.
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.
