The processing of highly reactive resin systems requires a detailed understanding of the material behavior during component manufacture. The characterization of systems using DSC to date has reached its limits, especially in the case of polyurethanes. A specially developed measuring cell, on the other hand, delivers better results.

The battery system is one of the heaviest components in the powertrain of an electric vehicle. The use of lightweight materials and high-volume production processes according to requirements and functionality offers significant potential to reduce weight without compromising on safety or performance. A new technology concept shows the particular advantages of using a modified direct process with a tailored material selection.

In a research project being carried out by the IKV and KTP, the influence of geometric and process parameters on the quality of the screw connection in the direct assembly of thermosetting plastics has been analyzed. The research results show that, in addition to the geometric design, the production parameters offer additional optimization potential for the reliability of the screw connection. The compactness and curing degree of the parts exert the largest influence.

Encapsulation protects the sensitive sensor technology from external influences. The direct screw connection enables secure mounting of the module.

Patient movements can severely affect the quality of MRI and CT images. A new approach detects the movements and subsequently incorporates them into the image evaluation by means of correction algorithms. This significantly improves the image quality. For the detection of the patient’s movements, the use of polymer optical fibers is suitable.

Within the “BarriFlex” joint project, novel nano-tailored materials with improved barrier properties against gas and water vapor were developed for packaging applications. These materials form the basis of new packaging concepts. Despite intensive research, much still remains to be done as regards diversity of materials, barrier specifications and more efficient manufacturing processes for new, inexpensive, easy-to-recycle and even renewable packaging products.

Thermosets are being increasingly used for packaging electronic devices, and offer good properties for this application. Direct overmolding of the components is particularly interesting here. However, achieving a successful product requires striking a balance between processability, thermal conductivity and reproducibility.

In direct packaging,  the electronic devices or components are directly overmolded with the molding compound

Currently, small wind turbines can hardly be operated profitably in landlocked regions. This drawback has now been overcome by the partners EAB Gebäudetechnik Luckau GmbH and the Chair of Polymer-based Lightweight Design at the BTU Cottbus-Senftenberg: passive smartblades made from 3D-printed molds adapt independently to wind conditions. This is achieved by an intelligent layer structure and its bending-torsion-coupling.

This newly developed rotor blade is especially suited for weak-wind regions and adapts independently to the wind load

To meet stringent flame retardancy demands of areas such as transportation and electronics, components based on thermosets increasingly require a soluble, non-powder flame retardant (FR) due to low layer thicknesses in the final product or due to liquid processing methods. Two flame-retardants developed by Clariant meet these requirements.
