On the Effect of the Heat Balance During Tribological Testing of Plastics

The infrared welding is a well-established process in the industrial production of parts in various applications. However, the complex emitter-material interaction, which influences the meltdown behaviour of the plastic parts, results in a high effort for the process setup. A smoking of the plastic parts is to observe in numerous industrial infrared welding processes. The correlations between the smoking of the plastic, its temperature and thermal-oxidative degradation as well as the mechanical properties of the resulting welds are unidentified yet. Furthermore, in industrial infrared welding processes often high changeover times and varying joining part temperatures are existent.

Contribution to Infrared Welding of Plastics in Industrial Manufacturing

The concept of bioplastics as sustainable and environmentally friendly materials has become increasingly interesting in both academia and industry. Consequently, many researchers have made great effort in developing bioplastic materials. As new challenging materials, there is still a lack of in-depth understanding of the process−structure−property relationships, especially in multi-phase component nanocomposites.

Driven by necessary energy and cost savings, plastics are increasingly applied as primary components in tribological systems. The trend is marked by research and development regarding the effectiveness of different material compositions in reducing friction and wear, in which friction induced heat is one of the main challenges.

Systematic Use of the Chemical Transformation of Magnesium Hydroxide — a New Approach for Polymer Tribology

To ensure better stability of expanded polystyrene insulation panels on the house wall, they are fastened with an additional polypropylene (PP) anchor. However, the fact that two different materials are used results in thermal bridges due to different thermal conductivities (TC), which can be seen visually as the formation of mold and algae, but also cause energy losses. The motivation for this work was to adjust the WLF of the two materials by using a filler, but not to negatively influence the mechanical strength of the anchor.

Continuous fibre-reinforced polymers (FRP), based on flat sheets, benefit from excellent weight-specific features. These include the possibility of load path optimised design and the option of functional integration. Consequently, FRP offer a high potential for lightweight design. Materials using thermoplastic-based polymers (so-called „organic-sheets“) allow fully automated and fast manufacturing based on their physical processing and are environmentally sustainable because of their recycling capability. Additionally, through improved optical and aesthetic characteristics, new applications can be developed for a mid to high scale production range.

Pultruded, fiber-reinforced tapes have so far only been tested destructively or optically non-destructively. It would therefore be desirable to have a non-destructive testing method that can detect cracks, inclusions and changes in the impregnation quickly and without contact, i.e. that can detect the complete tape volume in contrast to optical methods. The air-coupled ultrasonic method used in this work meets all these requirements.

Foam injection molding is a processing technology to produce foamed plastic parts in serials production, attaining an increasing interest and use in industry. However, the applications are limited due to insufficient knowledge of processing and mechanical properties, limited use of light-weight potential as well restricted surface qualities. All these drawbacks are associated with the cellular structure. The structure characteristics like skin layer thickness, cell size, density and uniformity are developed during procedure. Thus, controlling the cell formation process is the key to work against the restrictions and optimize mechanical properties.

Controlling cellular structure in thermoplastic foam injection molding – influence of processing and mold technologies

Due to the low thermal conductivity of the polymer matrix, fiber reinforced polymers exhibit a low thermal conductivity compared to metals. By increasing the thermal conductivity and thereby decreasing thermal stresses in the part, an enhancement of its lifetime can be expected.

Epoxy Based Carbon Fiber Reinforced Polymers with Enhanced Thermal Conductivity – Structure and Properties

Additive manufacturing, such as the selective laser sintering (SLS), provides the possibility to manufacture structures as 3D-MIDs tool free. The first three-dimensional circuit carriers are already manufactured by selective laser sintering. An established method is the LPKF-LDSprototyping process. Different from conventional 3D-MIDs this process requires an ensuing coating of the additive manufactured circuit carrier with a metal compound containing substance to enable the direct structuring by laser. Commercially available materials for injection molded 3D-MIDs already contain certain additives for laser direct structuring, that can be activated by laser. Thus, the demand for functional powder compounds for the selective laser sintering process to design three-dimensional circuit carriers is mandatory.

Expandable polystyrene (EPS, coll. “Styropor”, “Unicell”, “Styrofoam”) is one of the most used foams. It accounts for one quarter of the current foam production in terms of volume. EPS has a multi-scale morphology since EPS parts consist of many fused foamed beads. The foamed beads themselves contain cells, which are formed of walls and struts as well as the cell gas. In this frame, a variation in bead size causes a significant change of surface area, which needs to be moulded, whereas the variation in cell size leads to an altered micro-morphology (cell walls and struts). However, the effect of the multi-scale morphology on the properties has never been studied in a comprehensive manner to the knowledge of the author. Hence, the aim of the work is the establishment of structure-property relationships as well as the clarification of their fundamental mechanisms for the purpose to be able to tailor the structure for a specific application. Thus, further material and cost savings could be possible. EPS and a bead foam made from a blend of polystyrene and polyethylene were studied regarding the effects of cell size, bead size and density on the mechanical and thermal behaviour. Furthermore, the distribution of polymer within a single bead was controlled by the introduction of a solid skin around the beads.

Epoxy-carbon fiber prepregs have been used increasingly by civil aerospace industry to manufacture the structural composite parts due to their excellent mechanical, thermo-mechanical and thermal properties at the cured state. Although carbon fibers are electrically conductive, due to the insulating nature of the epoxy matrix, epoxy-carbon fiber prepreg laminates mostly act as a semiconductor in the through-thickness direction. Nowadays, an enhanced through-thickness electrical conductivity is as well desired for modern composite applications, where a certain level of electrostatic dissipation, electromagnetic shielding or an enhanced lightning strike resistance is necessary.
