IMPACT PERFORMANCE IN PP WITH PVA FIBER REINFORCEMENT
Claudia Pretschuh (Wood K plus - Competence Centre for Wood Composites and Wood Chemistry) Lukas Sobczak (Borealis Polyolefine GmbH) Dietmar Salaberger (University of Applied Sciences Upper Austria) Michael Jerabek (Borealis Polyolefine GmbH) Thomas Lummerstorfer (Borealis Polyolefine GmbH)
PVA fibers are acting as very efficient impact modifier for PP homopolymers. Very high notched impact strength values can be obtained, even at -20°C. Further the effect of coupling on the fiber-pull out behavior was presented.
INTERFACIAL DAMAGE AND LOAD TRANSFER MODELING IN SHORT FIBER REINFORCED COMPOSITES
Kevin Bonnay (ENSAM ) Nicolas Despringre (ENSAM ) Yves Chemisky (Arts et Métiers ParisTech) Fodil Meraghni (Arts et Métiers ParisTech)
Based on experimental observations for SFRC,an interfaciale damage law and an adapted shear lag model is proposed and validated. Using a single set of parameters,the model is able to reproduce the behavior of an SFRC under various loading directions.
INVESTIGATING FIBRE ORIENTATION, DISPERSION AND LENGTH REDUCTION IN LONG GLASS FIBRE REINFORCED INJECTION MOULDING
Fin Caton-Rose (University of Bradford) Peter Hine (University of Leeds)
An investigation into the orientation, distribution and breakage of short and long fibres during the injection moulding process.
MICROSTRUCTURE AND FRACTURE PROPERTIES OF GLASS FIBER-REINFORCED POLYAMIDE 66 WITH HIGH VOLUME FRACTION OF GLASS FIBERS
Kazuya Mizumoto (YKK corporation) Kazuaki Sanada (Toyama Prefectural University) Makoto Kawagoe (Toyama Prefectural University) Mai Mizubayashi (YKK corporation)
This paper presents the experimental results of fracture properties of injection-molded glass fiber/polyamide 66 composites.The amount of glass fibers was varied from 17 to 41 vol%.
A MORPHOLOGICAL INDICATOR FOR THE DESCRIPTION OF THE SHORT-FIBER POSITION EFFECT ON THE BEHAVIOR OF A PERIODIC RVE
François Rasselet (Safran Composites) Sébastien Joannès (MINES ParisTech) Emilie Roche (Safran Composites) Sébastien Pautard (Safran Composites) Jacques Renard (MINES ParisTech)
Definition of a local indicator based on the first neighbor distance in a short-fiber reinforced unidirectional composite allowing the comprehension of the effect of the microstructure on the global elastic behavior and to short-list of accurate RVEs.
PARTICLE LEVEL SIMULATION OF FIBER MOTION TO DETERMINE CONTINUUM BASED MODELS PARAMETERS FOR FIBER ORIENTATION PREDICTION
Camilo Perez (UW Madison) Andres Tapia (University of Wisconsin-Madison) Tim Osswald (University of Wisconsin-Madison)
A particle level simulation was used to simulate fiber suspensions in the concentrated regime. Parameters used in large scale simulations were obtained through this simulations, specifically the Interaction Coe_x000E_cient of the Folgar-Tucker model.
SIMULATION OF THE DAMAGE MECHANISMS OF GLASS FIBER REINFORCED POLYPROPYLENE BASED ON MICRO SPECIMENS AND 1:1 MODELS OF THEIR MICROSTRUCTURE
Sascha Fliegener (Fraunhofer IWM) Tobias Kennerknecht (Fraunhofer IWM) Matthias Kabel (Fraunhofer ITWM)
Micro tensile specimens are tested until failure. The microstructure of each individual specimen is reconstructed in the form of a finite element model. The experimentally observed damage behavior is accurately captured by the simulations.
THROUGH-PROCESS MODELING FOR ACCURATE PREDICTION OF SHORT AND LONG TERM ANISOTROPIC MECHANICS IN FIBER REINFORCED THERMOPLASTICS
Cathelin Julien (SABIC T&I Corporate Research & Development, Composites) Amin Sedighiamiri (Sabic ) Tim Van Erb (Sabic )
Through-process modelling for accurate prediction of short and long term anisotropic mechanics in fiber reinforced thermoplastics.
ANALYSIS OF VISCOELASTIC BEHAVIOUR OF ULTRA-THIN CHOPPED CARBON FIBER TAPE REINFORCED THERMOPLASTICS WITH DIFFERENT TAPE LENGTHS
Xiuqi Lyu (University of Tokyo) Jun Takahashi (University of Tokyo) Yi Wan (University of Tokyo)
Temperature dependence of UT-CTT have remarkable dependence on tape length. When testing temperature varies from -30 to 120 °C, the modulus variation ratio of UT-CTT (6 mm), UT-CTT (18 mm) and UT-CTT (30 mm) are around 32%, 23% and 20%, respectively.
CFRTP MECHANICAL PROPERTIES SIMULATION BY MORI-TANAKA MODEL AND EQUIVALENT LAMINATE METHODS
Yi Wan (University of Tokyo) Jun Takahashi (University of Tokyo)
CFRTP tenseil properties were simulated by mori-tanaka model and equivalent laminate methods, the Mori-Tanaka model have better accuracy in predicting tensile moduli while equivalent laminate method predicted better strength results.
