INVESTIGATION OF SOUND ABSORPTION AND VIBRATION DAMPING PROPERTIES OF FLAX FIBRE COMPOSITES
Le Quan Ngoc Tran (Singapore Institute of Manufacturing Technology) Kede Huang (National University of Singapore) Abhishek Vishwanath Rammohan (National University of Singapore) Wern Sze Teo (Singapore Institute of Manufacturing Technology) Heow Pueh Lee (National University of Singapore)
Sound absorption, sound transmission and vibration damping behaviour of flax fibre composites were investigated. The study showed the effects of fibre loading, fibre orientation and thickness on the sound and vibration properties of the composite.
MECHANICAL AND ACOUSTIC BEHAVIOUR OF POROSITY CONTROLLED BIOCOMPOSITE
Justin Merotte (EcoTechnilin SAS) Antoine Le Duigou (LIMATB-UBS) Alain Bourmaud (LIMATB-UBS) Karim Behlouli (EcoTechnilin SAS) Christophe Baley (LIMATB-UBS)
This paper studies the influence of a large range of porosity contents on the microstructure of biocomposites made from flax/PP nonwovens and correlates it to acoustic and tensile properties.
MECHANICAL BEHAVIOUR ANALYSIS OF FIBRE/MATRIX INTERFACE IN HEMP/EPOXY COMPOSITES BY DIGITAL IMAGE CORRELATION
Amélie Perrier (Institute Pprime) Fabienne Touchard (P' Institute) Laurence Chocinski-Arnault (Institute Pprime) David Mellier (Institute Pprime)
This work concentrates on strain field measurements around a hemp yarn in eco-composites under tensile loading by using DIC method. The local constitutive behaviours of the different constituents of the specimens could be approached by such analysis.
MECHANICAL PROPERTIES OF TOUGH PLASMA TREATED FLAX FIBRE THERMOPLASTIC COMPOSITES
Wilhelm Woigk (Institute of Polymer Engineering, FHNW) J. Rion (Bcomp AG) C. Fuentes (EMPA) Carlos Fuentes (KU Leuven) Aart Van Vuure (KU Leuven) Kunal Masania (ETH Zürich) Clemens Dransfeld (University of Applied Sciences and Arts Northwestern Switzerland)
This paper presents the mechanical testing results of elementary flax fibres, thermoplastic and thermoset matrix materials along with a particular focus on the performance of untreated and plasma treated flax fibre/co-polyoxymethylene composites.
MICROSTRUCTURE AND MECHANICAL PROPERTIES OF HEMP TECHNICAL FIBRES FOR COMPOSITE APPLICATIONS BY MICRO COMPUTED TOMOGRAPHY AND DIGITAL IMAGE CORRELATION
Carlos Fuentes (KU Leuven) Pieter Willekens (KU Leuven) Niels Hendrikx (KU Leuven) Benjamin Lemmens (KU Leuven) Joren Claeys (KU Leuven) Jorma Croughs (Campus GroupT, KULeuven) Christine Dupont-Gillain (Université Catholique de Louvain) David Seveno (KU Leuven) Aart Van Vuure (KU Leuven)
Strain mapping analysis was used for evaluating the local mechanical behaviour heterogeneity along technical hemp fibres, revealing 3 types of tensile stress-strain curves depending on their strength, and a complex pattern of strain concentrations.
MICROSTRUCTURE, QUANTIFICATION AND CONTROL OF DISLOCATIONS IN BAST-TYPE PLANT FIBRES
Bo Madsen (Technical University of Denmark) Catherine L. Lester (Technical University of Denmark) Ulrich A. Mortensen (Technical University of Denmark) Mustafa Aslan (Karadeniz Technical University) Hans Lilholt (Technical University of Denmark)
Dislocations in plant fibres are investigated by using microscope and image analysis techniques. Straining of fibres, together with wetting, is applied to change the dislocation content. The effect is evaluated by tensile testing of fibres.
OPTIMIZED BAST FIBER REINFORCED POLYPROPYLENE FOR AUTOMOTIVE APPLICATIONS
Florian Gortner (Institute for Composite Materials) Luisa Medina (Institute for Composite Materials) Peter Mitschang (Institute for Composite Materials)
This paper deals both with the influence of the processing conditions on the mechanical properties and with the mechanical characterization of natural fiber reinforced polymer composites (NFRPC) with an area weight of 1700 g/m².
EFFECT OF MOISTURE ABSORPTION ON SELECTED MECHANICAL PROPERTIES OF NATURAL FIBER COMPOSITES BASED ON WOVEN FLAX FIBERS AND POLYPROPYLENE
Markus Wolfahrt (Polymer Competence Center Leoben GmbH) Oliver Rausch-Schott (Polymer Competence Center Leoben GmbH) Judith Sinic (Wood Carinthian Competence Center) Stefan Pichler (Wood Carinthian Competence Center) Guenter Wuzella (Wood Carinthian Competence Center)
In this work, an experimental investigation has been carried out to study the effect of moisture absorption on the tensile, flexural and impact properties of an unbalanced woven flax fiber/maleic anhydride grafted polypropylene composite.
SINGLE STEP FUNCTIONALISATION OF CELLULOSES WITH DIFFERING DEGREES OF REACTIVITY AS A ROUTE FOR IN-SITU PRODUCTION OF ALL-CELLULOSE NANOCOMPOSITES
Koon-Yang Lee (Imperial College London) Alexander Bismarck (University of Vienna)
A method of manufacturing all-cellulose nanocomposites using a single step functionalisation of two different celluloses with differing reactivities is presented.
THE POTENTIAL OF EUROPEAN BAMBOO FIBRE FOR COMPOSITE APPLICATIONS: A CHEMICAL-MECHANICAL APPROACH
Delphine Depuydt (KU Leuven) Nick Sweygers (Department of Chemical Engineering, Laboratory for Applied Physical Chemistry and Environmental Technology) Lise Appels (Department of Chemical Engineering, Laboratory for Applied Physical Chemistry and Environmental Technology) Jan Ivens (KU Leuven) Aart Van Vuure (KU Leuven)
The presented work investigates the tensile properties as well as the sorption behaviour and chemical composition of European bamboo fibres.
