Why You Need Carbon Fiber UD Tape Slitting Machine

In this article, we will introduce a carbon fiber UD tape slitting machine that can be used for slitting narrow uni-directional tape/ prepreg tape with high speed and high efficiency.

JT-SLT-320X UD Tape Slitting Machine 800

At the beginning of 2020, we got one inquiry from one world-glass enterprise who is in carbon technology for many years and had a deep industry background.

They ask if we can supply a narrow strip slitting machine for 6.35mm, which will be used for their new business in China.

Based on 10 more years’ experience, we were glad to approve this request.

The main reason is that our customer wants to slit the normal 300mm wide reinforced thermoplastic carbon UD tapes into narrow strands at 6.35mm (1/4″) and 12.7mm (1/2″), then it will be used for the automatic filament winding, automated fiber placement, automatic tape laying, etc.

On the basis of 10 years of accumulations on the CFRT UD tapes sliting and rewinding technologies.

More and more customers are required for the narrow prepreg tape slitting rewinding for both glass fiber and carbon fiber prepreg tapes.

We check all possible solutions but there is no suitable product on the market.

At last, we decide to use our own technology to develop this kind of narrow strip slitting rewinding machine that can satisfy their requirements and save cost at the same time.

In the whole process of carbon fibers, the carbon slitter rewinder has been a critical part.

Without it, all the thermoplastic unidirectional taps can’t be converted into the required width, no one can go on their process.

What is UD Tape Narrow Strip Slitting Rewinding Machine

UD Tape Narrow Strip Slitting Rewinding Machine is a special machine for winding, rewinding, and slitting the narrow strip of Reinforced Thermoplastic or Thermoset UD tapes.

The machine is equipped with a PLC and HMI to ensure constant tension on the tape. The rollers are made of alloy steel for anti-adhesive. The tape is wound around the reel with high precision, which reduces the number of slits in the tape during cutting. the precis is minus 0.125mm

How does the Carbon UD tape Slitting Machine Work?

The UD tape slitting and rewinding machine (Carbon UD Tape Rewinder) is a special tape slitter and rewinder made for carbon fiber tapes.

It was made by Jota machinery’s own teams and has the qualities of high precision and low noise.

The UD tape slitting machine works by unwinding the carbon UD tape mother tapes into the machine and running them through a set of rubber NIP rollers.

The rollers help the machine keep going fast.

The rollers also put tension on the carbon UD tape, which keeps it from slipping off the rollers while it is being used.

Next, after the carbon UD tape has been fed through the rollers, it goes through a round disc slitting blade assembly that cuts it into narrow strips.

The slitting blade will cut each strip at an angle so that they can be wound onto a reel later to make a finished product without any flaws or burrs.

After being cut into strips and wound onto reels, the strips are put in a rewinding machine where they can be used again if needed or sold as finished products.

What is unidirectional tape?

Unidirectional prepreg tape is a type of composite material that is commonly used in the aerospace, automotive, and marine industries for lightweight and high-strength applications.

It is made by impregnating continuous fibers with a thermoset resin and then curing the resin to create a rigid and durable material.

The fibers in unidirectional prepreg tape are aligned in a single direction, which gives the material its name.

This alignment allows for greater strength and stiffness in that direction, making it ideal for applications where the material will be subjected to high stress or tension.

One of the key benefits of unidirectional prepreg tape is its versatility.

It can be used to create complex shapes and structures, and can be layered and combined with other materials to achieve specific properties.

It can also be easily cut and shaped to fit specific design requirements, making it a popular choice for custom applications.

Another benefit of unidirectional prepreg tape is its consistency.

Because the fibers are aligned in a single direction and the resin is evenly distributed, the material has consistent strength and properties throughout.

This allows for precise and predictable performance in a wide range of applications.

Unidirectional prepreg tape is used in a variety of applications, including aerospace and aircraft manufacturing, automotive and racing components, wind turbine blades, and sporting equipment such as tennis rackets and golf clubs.

Its high strength-to-weight ratio and versatility make it an attractive option for designers and engineers who are looking for lightweight, durable, and high-performance materials.

In summary, unidirectional prepreg tape is a composite material that is made by impregnating continuous fibers with a thermoset resin.

Its unique properties, including high strength, stiffness, and consistency, make it an ideal choice for a wide range of applications where lightweight and high-strength materials are required.

As technology continues to advance, unidirectional prepreg tape is likely to play an increasingly important role in the development of new and innovative products across a wide range of industries.

What is the difference between thermoset and thermoplastic carbon fiber?

Thermoset and thermoplastic carbon fiber composites are two different types of carbon fiber materials that have unique properties and characteristics.

Thermoset carbon fiber composites are made by combining a thermoset resin, such as epoxy or polyester, with carbon fibers.

Once the resin is cured, it creates a rigid and durable material that cannot be reshaped or re-melted.

Thermoset composites are known for their high strength, stiffness, and resistance to heat and chemicals.

They are commonly used in applications that require a high level of performance and durability, such as in aerospace, automotive, and sporting equipment.

Thermoplastic carbon fiber composites, on the other hand, are made by combining carbon fibers with a thermoplastic resin, such as nylon, polypropylene, or PEEK. Unlike thermoset composites, thermoplastic composites can be reshaped and re-melted multiple times without degrading the material.

This allows for more flexibility in the manufacturing process and makes it easier to recycle the material.

Thermoplastic composites are known for their toughness, impact resistance, and chemical resistance.

They are commonly used in applications where durability and flexibility are important, such as in automotive, aerospace, and consumer goods.

In terms of mechanical properties, thermoset composites typically have higher strength and stiffness than thermoplastic composites, but thermoplastic composites have better impact resistance and toughness.

Thermoset composites also tend to be more resistant to heat and chemicals, while thermoplastic composites are easier to recycle and reuse.

The choice between using thermoset or thermoplastic carbon fiber composites depends on the specific requirements of the application.

If high strength and stiffness are the primary requirements, then thermoset composites may be the best choice.

If durability, impact resistance, and ease of recycling are important, then thermoplastic composites may be a better option.

In some cases, a combination of both thermoset and thermoplastic composites may be used to achieve the desired properties.

Which type of resin is considered to be a thermoplastic?

Thermoplastic resins are a type of polymer that can be repeatedly melted and solidified without undergoing significant chemical changes.

They are different from thermoset resins, which undergo a chemical change during curing and cannot be re-melted.

There are several types of resins that are considered to be thermoplastic, including:

  1. Polyethylene (PE): PE is a commonly used thermoplastic resin that is used in a wide range of applications, from packaging materials to automotive components.
  2. Polypropylene (PP): PP is another widely used thermoplastic resin that is known for its toughness, chemical resistance, and versatility. It is used in a variety of applications, including packaging, automotive, and medical devices.
  3. Polyvinyl chloride (PVC): PVC is a thermoplastic resin that is known for its durability, flexibility, and resistance to chemicals and weathering. It is used in a variety of applications, including building materials, electrical cable insulation, and medical devices.
  4. Polycarbonate (PC): PC is a thermoplastic resin that is known for its high impact resistance, optical clarity, and heat resistance. It is used in a variety of applications, including automotive parts, electronic components, and medical devices.
  5. Polyamide (PA): PA, also known as nylon, is a thermoplastic resin that is known for its toughness, abrasion resistance, and chemical resistance. It is used in a variety of applications, including automotive parts, electronic components, and textiles.

In the context of carbon fiber composites, thermoplastic resins are often used as matrix materials due to their ability to be re-melted and reshaped.

This allows for more flexibility in the manufacturing process and makes it easier to recycle the material. Some commonly used thermoplastic resins in carbon fiber composites include polyamide (PA), polyetheretherketone (PEEK), and polypropylene (PP).
