CFRP UD Tape Slitter Spooler Machine FAQ Guide


CFRP definition

CFRP is an abbreviation for carbon fiber reinforced plastic or carbon fiber reinforced polymer (CFRP).

Carbon fiber reinforced plastic/polymer is a composite material, it is formed by carbon fiber as the reinforcement and resin, metal, ceramic, cement, or rubber as the matrix.

This material has high specific strength and rigidity, it is light and widely used in aerospace, military, and automotive industries.

CFRP properties

  • Lightweight, high strength, high modulus

Carbon fiber density is 1.6-2.5g/cm3, its tensile strength is above 2.2Gpa.

Because of this, CFRP is widely used in aerospace, automotive industry, sports equipment, etc.

  • Thermal expansion coefficient is small

The thermal expansion coefficient of most carbon fibers indoors is below 0, carbon fiber deformation probability due to thermal expansion and contraction is very small.

  • Good thermal conductivity

Different from general inorganic and organic materials, the thermal conductivity of carbon fiber is close to that of steel.

Taking advantage of this property, CFRP can be used as material for solar collectors and thermally conductive shells.

  • Good chemical resistance

CFRP has stable corrosion resistance to acids, alkalis, and organic chemicals, and can be used to make a variety of chemical anticorrosive products.

  • Good wear resistance

Carbon fiber and metal are rarely worn when rubbed against each other.

Carbon fiber is used to replace asbestos to make advanced friction materials, which can be used as brake pad materials for airplanes and automobiles.

  • Good high-temperature resistance

The performance of carbon fiber is very stable below 400℃, and even at 1000℃, there is still not much change in performance.

Therefore, carbon fiber composite materials can be widely used in the aerospace industry as high-temperature resistant materials.

  • Outstanding dam and excellent sonar-penetration performance

Utilizing these 2 characteristics, it can be used as the structural material of submarines, such as the sonar dome.

  • High X-ray transmittance

This feature has been used in medical equipment.

  • High fatigue strength

Carbon fiber structure is stable, and the composite material made from it has a strength retention rate of 60% after being subjected to stress fatigue cycle tests millions of times.

CFRP price

CFRP is usually sold in the form of sheets, and the price is calculated in square meters.

And according to the number of monofilaments in the carbon fiber tow, CFRP sheets have different specifications, such as: 1K, 3K, 6K, 12K, 24K, 48K.

1K, 3K, 6K, and 12K are small tows, ≥12K are large tows are larger than.

The production cost of large tow is lower than that of small tow, so the smaller the K value, the higher the CFRP material price.

In the Chinese market, take the 3K CFRP material as an example: MOQ is 10 square meters, and the price is $55/square meter.

UD Tape

Unidirectional tape

Carbon fiber unidirectional tape is a non-woven fiber-reinforced material, all fiber strength extends in the same direction.

The longitudinal tensile strength of this non-woven fiber-reinforced material is very strong.

This is the biggest advantage of carbon fiber unidirectional tape, and also their biggest disadvantage.

They are not suitable for the production of parts that require anisotropic strength, such as auto parts, which require all-round strength enhancement.

In this case, fiber reinforced materials such as plain weave, twill or satin weave are required.

Thermoplastic UD tape

Thermoplastic UD tape is a unidirectional prepreg tape made of thermoplastic resin.


Thermoset UD tape corresponds to thermoplastic UD tape, which is made of thermosetting resin.

In the past, only thermoset UD tape could be used in the production of aerospace vehicles, because thermoset UD tape can still maintain structural integrity under high-temperature conditions;

Thermoplastic UD tape is difficult to be used in the production of aerospace vehicles because of its low melting point.


However, because thermoset UD tape can’t be heated or reshaped, while thermoplastic UD tape can be recycled, many companies are now focusing on upgrading the production process of thermoplastic UD tape.

Japan’s Teijin Group announced on January 31, 2019, that their thermoplastic carbon fiber unidirectional prepreg tapes have been officially certified by Boeing.

It means that the Teijin thermoplastic carbon fiber unidirectional prepreg tapes will be used to produce the main structural components of Boeing aircraft.

CFRP UD Tape Slitter

CFRP UD tape slitter is usually a narrow web slitter, Jota CFRP UD tape slitter’s unwinding width is 250mm, slitting width is usually 3.175mm/0.125″, 6.35mm/0.25″ and 12.7mm/0.5″.

If the jumbo roll width is too large, the slit width of 2 side strips and middle ones will be very different.

If the strip width is too different, it will further affect the use of automated tape laying equipment (ATL) and automated fiber placement machines.


Not only will it not save raw materials, but it may also affect the quality of automobiles and aircraft.

In order to control the slit width tolerance as much as possible, we Jota designed the unwinding width to be 250mm, such unwinding width can avoid the accumulation of slit width tolerances.

UD Tape Slitter Spooler

Traverse winding

Traverse winding is also called spooling.

Traverse winding process is generally divided into 2 types, one is that the spooling shaft will move laterally while rotating;

The other is that the lay-on arm against spooling shaft moves laterally, and the rewinding shaft rotates.

Jota UD prepreg tape slitter spooler machine adopts the first type traverse winding, the spooling shaft moves laterally while rotating.

UD tape slitter traverse winder

UD tape slitter traverse winder is also called UD tape slitter spooler.

According to the operating process of UD tape slitter traverse winder, it mainly includes the following parts:

  • Unwinding
  • Release paper and resin film winding
  • Tape slitting
  • Tape waste edge collecting
  • Strips overhead threading and transporting
  • Strip spooling and resin film laminating

The UD tape jumbo roll with release paper and resin film layer is manually loaded onto the unwind stand.


After unwinding starts, the release paper and resin film are respectively wound on 2 rewinding reels.

After the UD tape is slit, the waste edge is wound on the waste edge winding shaft.

After slitting, the strips are connected to the spooling & laminating station through overhead guiding and transporting, and are wound on spool at the spooling laminating station.
