This study explores the shape-morphing behavior of 4D-printed structures made from Polylactic Acid (PLA), a prominent bio-sourced shape-memory polymer. Focusing on the response of these structures to thermal stimuli, this research investigates how various printing parameters influence their morphing …

This study starts with a literature review on SLS-printed PA12 and how its ductility is influenced in the printing process as well as by post processing. The rest of the study focuses on one particular post processing technique, heat treatment under isostatic pressure, including an experimental phase …

The prediction of mechanical elastic response of laminated hybrid polymer composites with basic carbon nanostructure, that is carbon nanotubes and graphene, inclusions has gained importance in many advanced industries like aerospace and automotive. For this purpose, in the current work, a hierarchical, …

From 2015 till present, the Professorship for Polymer Engineering has developed the principle of structural re-use of End-of-Life (EoL) thermoset composite products. The method is based on keeping the composite structure of EoL products but machining them into smaller parts, either strips or flakes, …

The present study deals with the numerical modelling of hybrid laminated composites, which can be proved especially useful in the engineering and maintenance of advanced aerospace primary structures. The lamina is comprised of continuous carbon fibers, thermosetting epoxy polymer matrix, as well as carbon …

In this study, an existing injection mould was partially optimized by adding CCCs to one of the mould inserts. The insert was additively manufactured in stainless steel using Selective Laser Melting. Simulations of the cooling process in the injection mould show that hot spots are eliminated, but the …

In the recent past, the use of resins in modern tread compounds has increased considerably, in order to further improve tire properties. Based on the experience with silica-silane filler system, which led to a different network structure and a significantly changed devulcanization behavior, the influence …

Within the context of the research programme “Koenst), a natural gas (methane) fuelled heater (Prototype I1) for injection moulding has been developed. When tested, the first prototype of this natural gas fuelled heater showed cracks at some specific spots, especially certain corners inside the hull. …

Tires are an important vehicle component, as car handling, safety and fuel economy depend for a major part on the tire composition and construction. As a consequence, tires are improved continuously. The most prominent improvement in the recent past was the use of a silica-silane filler system in passenger …
