“…As long fiber composites are increasingly considered for door assembly components, it is imperative to study the material's dynamic performance under periodic stress to determine the viscoelastic behavior [22]. Dynamic mechanical analysis (DMA) provides information on the process usability of these materials, information on end-user performance, and is key to guaranteeing service performance [23].…”

To maximize the driving range and minimize the associated energy needs and, thus, the number of batteries of electric vehicles, OEMs have adopted lightweight materials, such as long fiber-reinforced thermoplastics, and new processes, such as microcellular injection molding. These components must withstand specific loading conditions that occur during normal operation. Their mechanical response depends on the fiber and foam microstructures, which in turn are defined by the fabrication process. In this work, long fiber thermoplastic door panels were manufactured using the Ku-FizzTM microcellular injection molding process and were tested for their impact resistance, dynamic properties, and vibration response. Material constants were compared to the properties of unfoamed door panels. The changes in mechanical behavior were explained through the underlying differences in their respective microstructures. The specific storage modulus and specific elastic modulus of foamed components were within 10% of their unfoamed counterparts, while specific absorbed energy was 33% higher for the foamed panel by maintaining the panel’s mass/weight.

“…245 Typically, the addition of nanofillers can dramatically increase the cell density of polymer foams (see Figure 2.18) by rendering heterogeneous nucleation favorable over homogenous nucleation. 246 Colton and Suh were the first to demonstrate the use of nanofillers in polymer foaming. [247][248][249] They reported that a high cell density was achieved by adding zinc stearate as the heterogeneous nucleation agent in polystyrene (PS) foaming.…”

Silicon-containing nanoparticles are considered a promising class of materials with exciting physical properties and the potential to revolutionize many emerging application areas. This Chapter introduces the fundamental aspects of silicon-containing nanoparticles and their most common production approaches. In addition, we provide a comprehensive overview of the frontiers of silicon-containing nanoparticle research for the growing fields of printable Silicon-containing electronics, theranostics, nanocellular polymer foaming, and catalysis. We include an introduction to readily applicable particle surface modification strategies as well. Finally, the limitations and challenges for the successful commercialization of silicon-containing nanoparticles in the application fields mentioned are also presented and discussed.
