Rolled unidirectional tape of dry carbon fibres for light-weight applications

Summary

A German research institute, active in textile engineering, has developed a process including a pilot plant for demonstration for the production of a dry unidirectional (UD) material as a basis for multiaxial structures. The developed technology allows manufacturing a rolled UD tape of dry carbon fibres, which can be used for improved production of scrims. The institute is interested in a license and/or technical cooperation agreement.

Partner sought

The institute is looking for partners from industry, which deal with applications in the fields of: - Shipbuilding - Compressed gas tanks - Construction and building products - Wind turbines - Aircraft constructions - Automotive - Sporting goods Tasks to be performed are joint further development, testing of new applications and adaptation to specific needs.

Description

A German research institute, active in textile engineering, has developed a process including a pilot plant for demonstration. The increasing use of carbon fibre materials, e.g. in airplane and automotive engineering, requires automated manufacturing solutions. The currently common prepreg solutions are expensive and not suitable for large-scale production. The new process including the developed plant technology allows manufacturing a rolled unidirectional tape of dry carbon fibres. The fibre spreading is realised in one to two planes. The tapes can also be made of different materials with different weights per unit area. Thereby the homogeneous fibre tape consists of a large number of single tapes without transverse cohesion between them. The development enables the improvement of processing of carbon fibres for composites. The unidirectional materials are suitable for use in various applications, they facilitate the production of new non-crimp fabrics on multiaxial machines/multiaxial multiply fabrics in a better quality as well as with higher productivity. Main fields of application of the final product are: - Shipbuilding - Compressed gas tanks - Construction and building products - Wind turbines - Aircraft constructions - Automotive - Sporting goods The institute is interested in a license agreement and/or a technical cooperation agreement. Main fields of application of the final product are: - Shipbuilding - Compressed gas tanks - Construction and building products - Wind turbines - Aircraft constructions - Automotive - Sporting goods The institute is interested in a license agreement to transfer of rights involving the authorization for using the licensed material and/or in a technical cooperation agreement with a partner with specific technological capacities for a further development.

Advantages and innovations

This technology allows improving the processing of carbon fibres for composites significantly. Thus, it is an efficient alternative to the existing prepreg solutions. The UD fabrics can be used for thermoplastic and thermoset fibre composites for lightweight applications. Compared to conventional prepregs, there is a shortened process chain. Thus, the process becomes faster and more cost-effective. The storage of the material is not limited in time and does not depend on cold storage cells. Compared to woven fabrics, the UDs offer a maximum material performance caused by the stretched fibre arrangement. The material is gap-free and has an uniform weight per unit area over the entire material width. The UD fabrics offer a great flexibility concerning the structure of the fibre composite. Special functions can be integrated. The cycle times for the production of the components can be shortened.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
