THERMOPLASTIC COMPOSITES FORMING SIMULATION. VISCOSITY AND THERMAL INFLUENCE ON DRAPING.
Eduardo Guzman maldonado (INSA de Lyon) Hu Xiong (INSA de Lyon) Hamila Nahiene (INSA de Lyon) Philippe Boisse (INSA de Lyon)
The simulation of thermoplastic prepreg forming is achieved by alternate thermal and mechanical analyses. The thermal properties are obtained from a mesoscopic analysis and a homogenization procedure.
FINITE ELEMENT ANALYSIS OF 3D WOVEN COMPOSITE T-JOINTS UNDER TENSILE LOADING
Shibo Yan (Univerisity of Nottingham) Andrew Long (University of Nottingham) Xuesen Zeng (University of Nottingham)
This paper presents a voxel-based method to predict the non-linear response and damage initiation for 3D woven composite T-joints, by incorporating realistic fibre geometry and cohesive zone model for meso-scale analysis.
FINITE ELEMENTS ANALYSIS VERSUS EXPERIMENTAL TESTING FOR A CFRP STRUCTURE
Ricardo Sa (University of Minho) Ricardo Ferreira (PIEP - Innovation in Polymer Engineering) Nuno Goncalves (PIEP - Innovation in Polymer Engineering) Nuno Vieira (PIEP - Innovation in Polymer Engineering) João P. Nunes (University of Minho) F. W. J. van Hattum (Saxion University of Applied Sciences)
To validate the finite elements model at the basis of the optimization process a scale model prototype of the composite structure was built and tested. The experimental results were then compared with those obtained from numerical simulations
FROM A MICRO-CT IMAGE TO MODELS OF THE INTERNAL GEOMETRY, DEFECTS, MICROMECHANICS AND PERMEABILITY OF TEXTILE COMPOSITES – VOXTEX SOFTWARE
Ilya Straumit (KU Leuven) Stepan Lomov (KU Leuven) Nghi Nguyen (KU Leuven) Martine Wevers (KU Leuven)
Software VoxTex analyses a micro-CT image of a textile composite and transforms the image into a voxel model in which the fibrous structure of the reinforcement (fibre volume fraction and fibre direction) is identified for each voxel.
INFLUENCE OF VOID CONTENT ON THE MECHANICAL PROPERTIES OF CARBON/PPS LAMINATES
Julien Patou (Université de Toulouse) Emmanuel De-Luycker (Université de Toulouse) Gerard Bernhart (Université de Toulouse)
Void content of several carbon fiber/PPS powdered laminates was investigated to assess the impact of porosity level on mechanical properties of thermoplastic materials. Mechanical properties were measured and results were related to void content.
CHARACTERISATION OF THE EFFECT OF THROUGH-THICKNESS REINFORCEMENT ON IMPACT TOLERANCE AND OUT-OF-PLANE TENSILE PROPERTIES OF COMPOSITE MATERIALS
Winifred Obande (Univeristy of Limerick) Walter Stanley (University of Limerick)
Two types of carbon-fibre reinforced benzoxazine composites have been manufactured to characterise the effect of reinforcement architecture on impact and out-of-plane tensile performance. Results and observations are presented in this paper.
MESO-FE DAMAGE MODELLING OF 3D TEXTILE COMPOSITES USING MESH SUPERPOSITION METHOD
Ahmad Tabatabaei (KU Leuven) Enrico Bedogni (Università di Parma) António Melro (University of Bristol) Dmitry Ivanov (University of Bristol) Stepan Lomov (KU Leuven)
The intra-yarn and matrix damage in a multi-layer 2D plain weave glass/epoxy composite is modeled with mesh superposition (MSP) method and the results are compared with the experiments.
MODELING OF THROUGH-THICKNESS INTRA-YARN FIBER VOLUME FRACTION GRADIENTS IN LAMINATED WOVEN FABRICS
Mike Mühlstädt (Friedrich Schiller University Jena) Wolfgang Seifert (Friedrich Schiller University Jena) Stefan Maenz (Friedrich Schiller University Jena) Klaus D. Jandt (Friedrich Schiller University Jena) Jörg Bossert (Friedrich Schiller University Jena)
This study presents a method to quantify intra-yarn fiber volume fraction gradients (IY-FVFG) within laminated plain woven fabrics. A model was proposed to describe IY-FVFG. In addition, the formation of IY-FVFG was investigated.
MODELLING OF THE MECHANICAL RESPONSE OF THERMOPLASTIC MATRIX TEXTILE COMPOSITES UNDER DYNAMIC LOADING – A COMPARISON OF METHODS
Jens Wiegand (Compact Engineering) Holger Boehm (Technical University of Dresden) Andreas Hornig (Technical University of Dresden) Jan Luft (Technical University of Dresden) Maik Gude (Technical University of Dresden)
The paper presents a comparison of Continuum Damage Mechanics and Plasticity methods for the modelling of thermoplastic matrix composites.
MODIFICATION OF ENERGY RELEASE RATES IN TEXTILE REINFORCED THERMOPLASTIC COMPOSITES TO CONTROL DELAMINATION CHARACTERISTICS
Moritz Kuhtz (Technical University of Dresden) Andreas Hornig (Technical University of Dresden) Maik Gude (Technical University of Dresden)
In the this study a modification strategy is presented to adjust the interlaminar properties and the corresponding delamination characteristics of a textile reinforced thermoplastic composite, consisting of glass fibre reinforced polypropylene.
