Why Are Slit Tapes Expensive and How Can New Innovations Reduce Costs for Composites Manufacturers?

Why slit tapes are expensive

Slit tape for Automated Fiber Placement (AFP) has been expensive due to several factors:

  1. Manufacturing process: Producing high-quality slit tape requires precise machinery and specialized cutting tools. The process typically involves slitting prepreg materials from large-width rolls, which adds complexity and cost to the production process.

  2. Quality control: Ensuring the quality of slit tapes is crucial, as it directly impacts the quality and production speed of the finished composite laminate. Maintaining high-quality standards requires advanced equipment, skilled operators, and strict quality control measures, which can increase production costs.

  3. Transportation and storage: Prepreg materials need to be stored and transported in climate-controlled conditions to maintain their quality. This adds extra costs in terms of storage facilities and specialized transportation.

  4. Limited market access: Historically, the cost of manufacturing slit tape has limited its use to the highest end of the composites market, such as aircraft stringers and fuselages. This limited market access contributes to higher prices for the end product.

Growing demand

With the introduction of more accessible automated fiber placement (AFP) systems like the ones from Addcomposites, combined with the increasing adoption of composite materials across various industries, the demand for slit tapes is expected to grow significantly. This growth can be attributed to several factors:

  1. Aerospace industry: As commercial aircraft manufacturers, such as Boeing and Airbus, continue to adopt advanced composite materials to reduce weight and improve fuel efficiency, the demand for high-quality slit tapes for AFP and ATL processes will increase.

  2. Automotive industry: The automotive sector is increasingly turning to composite materials to reduce vehicle weight, enhance fuel efficiency, and meet stricter emissions regulations. This shift is driving higher demand for slit tapes, particularly as high-volume production methods like AFP become more accessible.

  3. Wind energy: The wind energy sector is continuously looking for ways to improve the efficiency and performance of wind turbine blades. Using composite materials, including carbon fiber, has become a popular choice due to their high strength-to-weight ratio. This trend is expected to boost the demand for slit tapes in the production of wind turbine components.

  4. Sporting goods: Composite materials are increasingly used in the production of high-performance sporting goods, such as bicycles, tennis rackets, and golf clubs. As manufacturers seek to improve the quality and performance of their products, the demand for slit tapes is likely to rise.

  5. Infrastructure and industrial applications: Composite materials are being adopted in various infrastructure projects, such as bridges, buildings, and pipelines, due to their corrosion resistance, durability, and lightweight properties. As more industries embrace composite materials, the demand for slit tapes will grow.

Innovation possibilities!

New AFP players, like Addcomposites could develop a new, innovative tape slitting solution that can be easily integrated with existing AFP systems. This slitting solution could be designed to be compact, efficient, and user-friendly, making it suitable for small to medium-sized manufacturers or those requiring small-batch production of slit tapes. It could offer:

  1. Easy integration: The new slitting solution could be designed to easily integrate with current AFP systems, allowing manufacturers to streamline their production process without the need for extensive modifications to their existing equipment.
