QSP®: AN INNOVATIVE PROCESS BASED ON TAILORED PREFORMS FOR LOW COST AND FAST PRODUCTION OF OPTIMIZED THERMOPLASTIC COMPOSITE PARTS
Damien Guillon (CETIM) Damien Guillon (CETIM) Alain Lemascon (CETIM) Clément Callens (CETIM)
CETIM has developed a pilot line to produce in 1 minute complex composite parts able to fulfill the requirements of mass production industries: - from raw material to net shaped part, - production efficiency, - multi-thickness & multi-orientation.
AUTOMATED PRODUCTION OF CARBON FIBER REINFORCED THERMOPLASTIC SINE WAVE BEAMS
Frederic Fischer (German Aerospace Center) Matthias Beyrle (German Aerospace Center) Manuel Endraß (German Aerospace Center) Leonhard Häberle (German Aerospace Center) Thomas Stefani (German Aerospace Center) Matthias Gutschon (German Aerospace Center) Philipp Gänswürger (German Aerospace Center) Georg Braun (German Aerospace Center) Michael Kupke (German Aerospace Center)
With this paper DLR ZLP (AU) will give insight into current work on automated production of carbon fiber reinforced thermoplastic aerospace structures, via vacuum consolidation (OoA), hot press processing and implant resistance welding.
CERAMIC PRESSING TOOL FOR VARIOTHERMAL PROCESSING OF THERMOPLASTIC FIBER COMPOSITES
Florian Kühn (IVW GmbH) Luisa Medina (Institute for Composite Materials) David Becker (Institute for Composite Materials) M. Zwick (Forschungsinstitut für anorganische Werkstoffe – Glas/Keramik – GmbH) M. Knoch (FCT Ingenieurkeramik GmbH) B. Romahn (Weberit Werke Dräbing GmbH) Peter Mitschang (Institute for Composite Materials)
Development of tools made of the ceramic material silicon carbide (SiC) for variothermal processing of thermoplastic fiber composites with high energy efficiency as well as fast heating and cooling rates.
CONTINUOUS IMPREGNATION PROCESS BY FIXED ROLLERS DOUBLE BELT PRESS
Osuke Ishida (Kanazawa Institute of Technology) Gaku Fukushima (Kanazawa Institute of Technology) Junichi Kitada (SANDVIK K.K.) Toshihide Sekido (Kanazawa Institute of Technology) Kiyoshi Uzawa (Kanazawa Institute of Technology)
The continuous impregnation mechanism by fixed rollers double belt press was investigated. The process model was developed and evaluated experimentally. That will lead to obtain optimum process and improve machine capability.
DEVELOPMENT OF A NOVEL CONSOLIDATION PROCESS FOR CONTINUOUS-FIBER-REINFORCED THERMOPLASTICS
Sebastian Baumgärtner (Fraunhofer ICT) Christoph Lohr (Karlsruhe Institute of Technology) Frank Henning (Karlsruhe Institute of Technology)
A novel consolidation approach for thermoplactic composites was developed, in which a vacuum is used to apply pressure to the laminate while infrared radiation heats the thermoplastic material through a transparent mold wall.
DEVELOPMENT OF AN ADDITIVE MANUFACTURING PROCESS FOR THE PROCESSING OF ENDLESS FIBER REINFORCED POLYMERS
Matthias Domm (Institute for Composite Materials) Jonas Fischer (Institute for Composite Materials) Peter Mitschang (Institute for Composite Materials)
Polymer parts manufactured by Additive Manufacturing are limited in their achievable mechanical properties. In order to face this drawback, a concept was developed to process continuous fiber reinforced polymers with Additive Manufacturing.
DEVELOPMENT OF COMMINGLING NOZZLES FOR HYBRID YARN PRODUCTION BY CFD SIMULATION
Klaus Vonberg (RWTH Aachen University) Thomas Gries (RWTH Aachen University) Gunnar Seide (RWTH Aachen University)
The technique of Computational Fluid Dynamics is useful to analyse the flow field inside commingling nozzles. In the frame of this paper the procedure during the simulation is described and related to the commingling process.
IMPROVING PROCESSABILITY AND MECHANICAL PERFORMANCE WITH THE USE OF UNIDIRECTIONAL THERMOPLASTIC TAPES IN COMPRESSION MOLDING FOR AUTOMOTIVE STRUCTURAL APPLICATIONS.
Vincent Lutz (Plastic Omnium)
Different composite architectures were processed with unidirectional tapes in a large manufacturing set-up.
DIRECT THERMOPLASTIC MELT IMPREGNATION OF CARBON FIBRE FABRICS BY INJECTION MOULDING
Julia Studer (Institute of Polymer Engineering, FHNW) Clemens Dransfeld (University of Applied Sciences and Arts Northwestern Switzerland) Bodo Fiedler (Technische Universität Hamburg-Harburg)
The influence of the fabric architecture on the processing window for a through-thickness impregnation with thermoplastic melt is discussed by implementing the experimental compaction and permeability behaviour of two fabrics in a numerical analysis.
EXPERIMENTAL INVESTIGATION OF INTER-LAYER THERMAL CONTACT RESISTANCE AND ITS RELEVANCE FOR CONSOLIDATION OF THERMOPLASTIC COMPOSITES
Philipp Maximilian Schäfer (Technical University of Munich / Institute for Carbon Composites) Silke Kreuzhage (Technical University of Munich) Swen Zaremba (Technical University of Munich / Institute for Carbon Composites) Klaus Drechsler (Technical University of Munich / Institute for Carbon Composites)
Thermal processes are decisive for the efficient manufacturing of thermoplastic tapes. We developed a method for determining the inter-layer thermal contact resistance of consolidated and unconsolidated tapes and investigated CFRP PA-6 tapes.
