Large scale manufacturing technology
for high performance lightweight 3D multifunctional components
ca. 100 €
* … durable investment costs
The project 3D-LightTrans aims to provide a groundbreaking, highly flexible, efficient and adaptable manufacturing chain for the production of integral large scale 3D textile reinforced plastic composites (TRP). This will enable to shift them from its current position in cost intensive, small series niche markets, to broadly extended mass product applications in transportation and other key sectors, like health and leisure.
In the 3D-LightTrans manufacturing chain, multimaterial semifinished fabrics will be processed to deep draped prefixed multilayered and multifunctional 3D-textile preforms. Storage and transport of the fixed preforms takes place without special temperature requirements.

a) Multilayered fabrics
b) Spacer fabrics with hollow spaces manufactured in a single weaving step
Draping and fixation
TRP (textile reinforced plastic composites) combine light weight with excellent mechanical properties, while holding the potential for huge material cost savings in comparison with metal.
Reinforced composites (often carbon on thermoset matrix) are used for aircraft and a few niche automotive applications, but are too expensive for the mass market in spite of the lower material costs, due to the long processing cycles and labour intensity.
3D-LightTrans will create a manu-facturing chain able to exploit TRP’s inherent economic potential. 3D-LightTrans concept relies on individual processes and approaches, with suitability proven in experimental work performed at the TU-Dresden.
To achieve 3D-LightTrans goals, the partners will develop know-how, processes and equipment to establish automated production chains for low cost, high quality and reproducible industrial manu-facturing of large scale parts featuring complex 3D geometry.

The final composite part is produced by thermoforming. Neither manual draping of the textile onto the forming tool nor infiltration/curing are required, since preforms are already fixed in the desired 3D geometry and the thermoplastic matrix integrated in the hybrid yarn before weaving.
