Fiber and Filament Development

subject areas
Fiber Development focuses on research in the field of technical yarns made from new polymer raw materials and functionalized polymers for special applications in the technical sector as well as the corresponding process development. For this, standard, technical, high-performance and bio-based materials are first characterized with regard to their spinning behaviour in order to evaluate [...]

Joining

subject areas
Welding technologies for thermoplastic composite are enabling their efficient use. Depending on the materials and geometries of the parts which are to be welded, different technologies may be employed. Therefore, the electrical resistance welding, static and continuous ultrasonic welding are mainly investigated, while research on induction welding is conducted additionally. The FIBRE focusses on the [...]

Liquid Composite Molding

subject areas
Liquid Composite Moulding (LCM) processes are a widely used manufacturing techniques for fibre reinforced plastics. During the manufacturing process a dry preform gets impregnated by the liquid resin. The material is cured after the wetting process. The term LCM covers various processes, such as pultrusion, vacuum infusion or resin transfer moulding (RTM). Because of this, [...]

Non-destructive testing

subject areas
Non-destructive testing (NDT) is used in process monitoring, quality assurance, and material characterisation for fiber-plastic composites. Identifying quality issues at an early stage is important to save costs and material during the production process. NDT covers various methods such as image acquisition systems using industrial cameras combined with digital image processing or analysis of inner [...]

Overmolding

subject areas
With overmolding, a combination of processes is used to combine the advantages of (short fibre reinforced) injection molding with those of continuous fibre reinforced structural carriers. For this purpose, load-bearing fibre composite structural elements with thermoplastic matrix are functionalized by injection molding. The process is suitable for large-scale production and offers short process times with [...]

Recycling & Sustainability

subject areas
Recycling and sustainability play a major role in material development. The Fiber Institute is investigating the use of recycled carbon fibers on the one hand and the use of bio-based, degradable and recycled materials for fiber development on the other. The aim is to create efficient and environmentally friendly alternatives to conventional materials that protect [...]

Thermoforming

subject areas
In thermoforming, pre-consolidated thermoplastic fiber composite laminates or preforms are formed from fixed separate plies into complex shells, reinforcing structures or inserts for overmolding. The semi-finished material to be formed is melted in the IR heater field, draped onto the tool and shaped. The organosheets are handled automatically using a 6-axis robot or a lowerable [...]
