The Department of Polymer-based Lightweight Construction at the Brandenburg University of Technology Cottbus - Senftenberg is requesting a laying head for an existing Automated Fibre Placement system from Mikrosam(R). The tender will be divided into lots:

Lot 1: Single tape ATL head incl. delivery

The 2: Steuersystemverbesserung

The 3: Laseroptiken

Lot 4: fifth axis winding machine

Further information and requirements can be found in the SOW under the item “procurement documents”.

The department requests the following services for the above-mentioned lot:

- Guidance of a single thermoplastic tape (1/4" width) for small contours r <50mm

- It should be possible to place small shafts (r<50mm) through the head and pressurized gas tanks in also small diameters

- Recording of the temperature during the process by means of a pyrometer and thermal imaging camera

- Cooling of the dispenser against overheating at high temperatures

- Air pressure cooling of the guided tape during the depositing process

- Contact force range from 100 N to 500 N with continuous pressure control

- Processability of tapes with thicknesses between 0.1 and 0.3 mm

- Compatibility of the existing structure of Mikrosam(R) (UVgO §23 Abs.5)

- Tape spool type either Häfner or "Pancake"

- Vorspannkraft des Tapes: mind. 5 N

- Stand for the single tape head

- Automatic machine termination in case of faulty tape routing

Compatibility with Mikrosam(R) products is based on the existing system with a quadruple laying head. The new head should be able to be seamlessly integrated into the MikroPlace CAD environment. A heating source is also already available and integrated.

The department requests the following services for the above-mentioned lot:

-Calibration of the existing CAD system for the new head

-The existing KUKA CNC system is to be given increased movement accuracy through a new version

The department requests the following services for the above-mentioned lot:

- Adapted optics for the existing laser system

- Downscaling of the laser effective range from 1" to 1/4"

Furthermore, a fifth axis is requested for the winding system of the company Mikrosam(R).

This axis is intended to:

- Be compatible with the existing structure,

- be able to wind poles of high-pressure tanks more effectively,

- be able to process towpregs,

- Allow more geometry freedom compared to the existing system

- Compatibility of the existing structure of Mikrosam(R) (UVgO §23 Abs.5)

- Rotation angle of the fifth axis: +/- 45°

- Umdrehungsgeschwindigkeiten: 0 - 30 rpm
