DORNIER at JEC Paris 12-14 March 2019 Hall 6, Booth D43

DORNIER – Application-specific systems for manufacturing semi-finished products

Tapes, tape fabrics and 3D structured textiles: DORNIER presents machines and system solutions from its Composite Systems business unit for efficiently manufacturing the latest in semi-finished fiber composite products at JEC World (March 12-14 in Paris).


No expensive pressing processes: the tape weaving machine will make organic sheet production more efficient in the future


”At the JEC we will present the full range of our machine and system solutions for the composites industry”, says Dr. Josef Klingele, Head of Composite Systems. For tapes, tape fabrics and complex 3D fabrics, in the machines and production lines of the Composite Systems range, set up in 2014, the machine builder combines the unrivaled expertise collected in its globally respected Weaving Machines and Specialty Machines business units.

Carbon, glass, aramide and basalt: Roving weaving machine from DORNIER have woven semi-finished fibers for composites from high-performance fibers for over 40 years.

Particularly with the extremely versatile Roving weaving machine for processing high-performance materials like carbon, glass and aramid fibers, the family company on the shores of Lake Constance has been the preferred partner for technical weavers worldwide for over 40 years. With core skills in textile and plastic processing collected in its Composite Systems business unit, DORNIER is building its reputation as a reliable equipment provider partner for the burgeoning composite industry.

Weaving car and aircraft parts: the 3D rapier weaving machine from DORNIER is able to produce fabrics up to 25 mm thick

Complex 3D fabrics and multilayer structures

Very high dynamic loads, good impact resistance and outstanding damage tolerance – it is often the case that the requirements placed on modern composite components simply cannot be met with layered textile reinforcements. The solution:
multilayer, integrally reinforced 3D fabrics. These can be produced economically on 3D weaving machines from DORNIER.
With an innovative fabric guidance system, fabrics can be manufactured with thickness of up to 100 millimeters. For this, the textile weave pattern is first developed in a virtual environment and then transferred digitally to the weaving machine controller.


Latest machine generation for reinforcement fabrics

“Manufacturing technologies are in a permanent state of evolution and optimization”, says Klingele. These days, both dry and fully impregnated tapes can be produced in widths up to 600 millimeters on the DORNIER tape production line at manufacturing speeds as high as 30 meters per minute.

Then, the finished tapes are processed further on the tape weaving machine to create textiles which are ideal for structural reinforcement and design applications. “The latest machine generation is now available for fabric widths up to 285 centimeters”, adds Klingele. This represents a significant increase in productivity and less waste particularly for applications involving thermoplastic composite materials.


High-quality composites on custom-built systems

The challenges facing the composite industry are enormously diverse; no two machines for manufacturing semi-finished goods are the same. In order to meet specific customer requirements, DORNIER has established its own technology center where it develops and tests complex machine and system concepts for optimal production of semi-finished products jointly with the customer. For example, trials are conducted in a tape laboratory facility here on the manufacture of thermoplastically fully impregnated tapes, and of tape-based fabrics on a tape weaving machine. A 3D weaving machine for complex multilayer
fabrics and a high-performance weaving machine for flat weaves are also available for running tests. “It is just not possible to make the high-quality textile reinforcements needed for cars, aircraft and machine building on standard machines”, says Klingele.


Background information about Lindauer DORNIER GmbH:
Lindauer DORNIER GmbH and its Weaving Machine, Specialty Machine and Composite Systems divisions has earned its place as a global technology leader. In 2017, the German family enterprise employing more than 1,000 staff (including 63 trainees) and recorded an order intake of approx. 280 million Euros. The company set up the Composite Systems division with the Roving Weaving Machine, 3D Weaving Machine, Tape Production Line and Tape Weaving Machine as a collecting point for its decades of experience in the engineering weaving machines and building production plants for plastic films. The systems are configured according to customer specifications; consequently, the equipment of each machine varies – sometimes considerably – depending on the needs of the customer. All machines are manufactured in the production workshops at
Lindau and Esseratsweiler in Germany. 90% of the machines produced are exported.
