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 Design-to-Robotic-Production and -Assembly (D2RP&A) process developed at Delft University of Technology (DUT) has been scaled up to building size by prototyping of-site a 3.30 m high fragment of a larger spaceframe structure The fragment consists of wooden linear elements connected to a polymer node …

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, …

Sensor platforms can benefit from the incorporation of polymerbrushes since brushes can concentrate the analyte near the sensor surface. Brushesthat absorb acetone vapor are of particular interest since acetone is an importantmarker for biological processes. We present a simple procedure to synthesize …

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, …

Part of the project: TFF-Optimization of Mixing Elements. Polymer mixing with a single screw extruder is a common process in industry. Mixing quality depends on (amongst others) the screw geometry. The main objective of this study was to quantify distributive mixing behavior of a single screw extruder …

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. …
