Technology principle & technology portfolio:

  1. The powder form material is scattered onto the porous structure.

  2. The material is then placed between electrodes and an alternating electric field is applied to the product.

  3. At the end of the treatment, all the powder scattered on top of the support finds itself inside the porosities.

In most cases, a 1 to 5s residence time is sufficient, and leads to a homogeneous distribution of the powder inside the support. Gradient distribution is also achievable with adapted process parameters.

It is important to notice that no raise in temperature occurs inside the machine, and no static electricity remains inside the material at the end of the treatment.

Energy consumption of the whole system is very low: for instance, a 4m long and 1.20m wide unit running at 10m/min (impregnating up to 1T/h material) requires less than15kW.

Several configurations of those technologies are available, depending on targeted materials and expected production characteristics:

Flexibility & Efficiency:

The D-Preg process of Fibroline™ is an industrial, in-line process that has been proven to be reproducible, controllable and homogenous. Key advantages of the Fibroline™ D-Preg technology reside in its flexibility and adaptability to most of the porous structures, as well as its ability to precisely control impregnation depth.

Dedicated to high speeds:

Fibroline™ developed a specific version of the D-Preg process dedicated to high speeds: T-Preg. The T-Preg technology leads to shorter machines and is perfectly adapted to running speeds from 50 to 500m/min (technology suitable in particular for hygiene applications).

Low powder content & Pattern deposition:

Fibroline™ also extended its range of innovative solutions to applications requiring low powder content and extremely accurate powder distribution (S-Preg). This configuration is used in particular for Medical or Biomedical sectors, and can be implemented in clean rooms.

Dedicated to Yarns & Tapes:

Fibroline™ developed a specific electrode construction for Yarns & UD-tapes. Main applications are composite reinforcements. Several bobbins can be processed in parallel.

Developing innovative solutions with Fibroline™ R&D team…

Fibroline is equipped with a number of different installations, which permit the development of a large variety of products. Such installations enable to carry out tests or experiments from small size samples, to several tons in a continuous way.

With those facilities, Fibroline R&D team can scan all process parameters in order to select best adapted process conditions. Initial trials are carried out at Lab scale to validate the feasibility and potential of the application. Results are then transferred to Fibroline's continuous semi-industrial lines available for sampling or pre-productions, before final investment of the industrial partners.

1-Labscale impregnation units:

At a lab scale, Fibroline™ works on discontinuous impregnation devices that allow preliminary tests and R&D work. These devices can impregnate from the tiniest samples to A3 size samples in a very flexible way.

 

2-Pilot equipment for validation:

After a successful lab validation, Fibroline™ goes one step further with a continuous validation of the process. Product development results can thus be confirmed on semi-industrial equipment (any Fibroline configurations D-T-S-Y available for trials in the R&D center)

 

3-Technology transfer & Machine manufacturing:

Once the technical requirements are fulfilled and business model agreed between the parties, Fibroline industrialization team supports its industrial partner for the technology transfer of the solution, in close cooperation with selected machine manufacturer.

Fibroline™ established technical cooperation with different equipment partners depending on machine specifications (0.10 up to 5.5m width & speeds from 10 to more than 500m/min), and targeted markets.
