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.

Avoiding Filter Effects of  Flame Retardants

Short glass fiber-reinforced plastics are exposed to complex load cases during the operating time. Therefore, the influence of alternating load and frequency in the form of load spectra on material fatigue is investigated and an integrative computational method for structural design is presented. With this practical approach, a fast fatigue life estimation is possible.

Thermoplastic compounds with integrated electrical conductivity offer a potential solution to resolve EMI, EMS and electrostatic discharge challenges. These thermoplastic materials can deliver the appropriate level of electromagnetic shielding for electronics, while providing freedom to design complex geometries and opportunities to streamline processing by avoiding secondary operations.

Bio-based plastics can lock away vast quantities of CO<sub>2</sub> in durable, recyclable applications and make a real contribution to climate protection. All that is needed for this is the right product design and a functioning circular economy. By focusing more on this approach, the plastics sector has the chance to evolve into a key industry of a green economy.

Combining additive manufacturing with a digital, simulation-based design process makes it possible to develop even highly complex extrusion dies in a time-saving and economical manner. Experts from the Eastern Switzerland University of Applied Sciences and ETH Zurich have successfully applied this technique using the example of a novel co-extrusion die.

The Institute for Plastics Processing (IKV) at RWTH Aachen University is investigating a new control approach for injection molding in which the cavity pressure is controlled by different positions of the hot runner valve pin. The influence on the cavity pressure of different strokes in the holding pressure phase is investigated.

Infrared heating technology has become established as the standard in the processing of thermoplastic composite materials. The focus is on process control. On the one hand, it is important that the heating process is fast, on the other hand, the material must not be overheated. It is also important to achieve excellent temperature homogeneity. Simultaneous processing of blanks with different thicknesses is a particular challenge.

Air inclusions in fiber reinforced plastics (FRP) are among the most common imperfections that can affect both the resulting stiffness and strength. For the calculation of the stiffness of a perfect UD layer, semi-empirical mixing rules can be used which show good agreement with experimental data. Since the content of air inclusions is generally low compared to the constituents of an FRP, the Mori-Tanaka scheme can be exploited in a following step to homogenise the perfect phase and air inclusions. By introducing a geometry function into Mori-Tanaka scheme, influence of air inclusions’ appearance can be investigated.

Investigations and prediction of the melting processes in single-screw extrusion have been of scientific interest for many decades. In this study, the melting zone of a high-performance extruder with a continuous helically grooved plasticizing zone is experimentally investigated for the first time. For this purpose, an axially divisible extruder was developed to expose the barrier screw together with the plastic melt. An optical examination of the frozen melt validates assumptions of the existing melting model. In addition, the results of the experimental investigation are compared with those of the analytical model. These investigations confirm the essential mathematical model assumptions and are in good agreement with previous investigations on an axially grooved single-screw extruder.
