MECHANICAL PERFORMANCE OF LONG FIBRE REINFORCED STIFFENER PANELS MANUFACTURED USING LASER WELDING
Peter Hansen (Element Materials Technology) Verena Wippo (Laser Zentrum Hannover e.V.) Sean Cooper (AGC AeroComposites) Dave Conway (AGC AeroComposites) Choothum Jeenjitkaew (Element Materials Technology) Peter Jäschke (Laser Zentrum Hannover e.V.)
Laser transmission welding was applied to join glass fibre fabric reinforced polyetherimide materials in stiffened panels. Mechanical test were performed to compare the laser welded specimens with adhesively bonded coupons in static and fatigue tests.
MANUFACTURING OF A CARBON/POLYAMIDE BEAM BY VACUUM ASSISTED PULTRUSION
Felix Lapointe (Polytechnique Montreal) Arnold Oswald (Ecole Polytechnique Montréal) Asami Nakai (Gifu University) Louis Laberge Lebel (Ecole Polytechnique Montréal)
Carbon/PA thermoplastic composites were manufactured using vacuum assisted pultrusion. The effect of preheating methods, preheating temperatures, and vacuum level on the void content was studied.
MANUFACTURING OF BICOMPONENT FIBERS FOR THERMOPLASTIC COMPOSITES: A FEASIBILITY STUDY
Christoph Schneeberger (ETH Zürich) Joanna C. H. Wong (ETH Zürich) Paolo Ermanni (ETH Zürich)
We propose an alternative concept for hybrid intermediate materials used in high volume production of thermoplastic composites by dip coating individual glass filaments with a polymer sheath in-line with the glass spinning process.
NEW PRODUCTION PROCESS FOR MANUFACTURING CONTINUOUS FIBER-REINFORCED THERMOPLASTIC HOLLOW PROFILE COMPONENTS
Clemens Stefanziosa (BMW Group) Klaus Drechsler (Technical University of Munich / Institute for Carbon Composites) Elisabeth Ladstätter (Technical University of Munich / Institute for Carbon Composites) T. Zimmermann (Technical University of Munich / Institute for Carbon Composites)
This article is to present a newly developed discontinuous production process – that is subdivided into five main steps – for continuous fiber-reinforced thermoplastic hollow profiles based on a continuously produced semi-finished product.
ON LINE AND IN-SITU CONSOLIDATION OF THERMOPLASTIC
Riccardo Dell'Anna (University of Salento) Francesca Lionetto (University of Salento) Francesco Montagna (University of Salento) Alfonso Maffezzoli (University of Salento)
High power ultrasound was used in order to mould thermoplastic composites in a process including the simultaneous fibers impregnation and plies consolidation.
PROCESSING AND PROPERTIES OF FULL-THERMOPLASTIC SANDWICH STRUCTURES FOR APPLICATION IN AIRCRAFT INTERIORS
Mathias Muehlbacher (Neue Materialien Bayreuth GmbH) Thomas Neumeyer (Neue Materialien Bayreuth GmbH) Volker Altstädt (University of Bayreuth)
In this study an approach for manufacturing all-thermoplastic sandwich structures based on fire resistant thermoplastics for usage in aircraft interiors is presented.
RESISTANCE WELDING OF CARBON FIBER REINFORCED THERMOPLASTIC COMPOSITES USING SPREAD CARBON FIBER HEATING ELEMENT
Daiki Tanabe (Osaka University) Fumio Kubohori (Kindai University) Kazuaki Nishiyabu (Kindai University) Tetsusei Kurashiki (Osaka University)
The effects of processing conditions such as applied voltage, current and conducting time on the fusion behavior of CFRTP composites were investigated to get the optimum condition for resistance welding using spread carbon fiber heating element.
THERMOPLASTIC UNIDIRECTIONAL TAPES – AN APPROPRIATE ALTERNATIVE TO WOVEN FABRIC BASED ORGANIC SHEETS
Michael Kropka (Neue Materialien Bayreuth GmbH) Mathias Muehlbacher (Neue Materialien Bayreuth GmbH) Volker Altstädt (University of Bayreuth)
In this study, the mechanical properties of glass fiber reinforced organic sheets and UD-tape lay-ups were investigated and compared at different temperatures.
FILAMENT-WOUND COMPOSITE CYLINDERS WITH ARCH-SHAPED CROSS SECTIONS USING ULTRA-HIGH FIBER TENSION
Yang Wang (Wuhan University of Technology) Lei Zu (Wuhan University of Technology) Jihui Wang (Wuhan University of Technology)
The binding effect of fiber materials during the filament winding process was successfully simulated using the Finite Element Method (FEM). These results can be useful in designing the filament wound composite structure.
DESIGN OF A NEW TOOL WITH THE INTERMITTENT-SAWTOOTH STRUCTURE FOR DAMAGE REDUCTION IN DRILLING OF CFRP COMPOSITES
Rao Fu (Dalian University of Technology) Zhenyuan Jia (Dalian University of Technology) Fuji Wang (Dalian University of Technology) Youliang Su (Dalian University of Technology) Junwei Yin (Dalian University of Technology) Bin Niu (Dalian University of Technology) Wei Liu (Dalian University of Technology)
The analysis of the drilling damage is conducted and a novel one-shot drill is proposed with the intermittent-sawtooth structure based on the elastic foundation beam theory. Encouraging reductions on drilling damages are achieved by the novel drill.
