ARE FLAX-EPOXY COMPOSITES TOUGH?

Farida Bensadoun (KU Leuven) Ignaas Verpoest (KU Leuven) Aart Van Vuure (KU Leuven)

 

This study was to determine the influence of fibre architectures on the interlaminar fracture toughness of flax fibre epoxy composites.

BACTERIAL CELLULOSE AS REINFORCEMENT FOR NATURAL FIBRE THERMOSET COMPOSITES

Marta Fortea Verdejo (Universität Wien) Koon-Yang Lee (Imperial College London) Alexander Bismarck (University of Vienna)

 

Natural fibre composites were manufactured using flax fibres as reinforcement and different thermoset polymers as matrix. The effect of introducing bacterial cellulose as additional binder to these composites was investigated.

CELLULOSE NANOPAPER COMPOSITES: INFLUENCE OF NANOPAPER CHARACTERISTICS ON COMPOSITE PROPERTIES

Andreas Mautner (Universität Wien) Koon-Yang Lee (Imperial College London) Wan Wan Nawawi (Imperial College London) Alexander Bismarck (University of Vienna)

 

Cellulose nanopapers are promising scaffolds for composites. This study aims to develop methodologies to vary the porosity of nanopapers enabling improved resin infusion and investigate the influence of nanopaper properties onto composite properties.

EFFECT OF FIBRE VOLUME CONTENT ON THE MECHANICAL PERFORMANCE OF NATURAL FIBRE REINFORCED THERMOPLASTIC COMPOSITES

Kunal Masania (ETH Zürich) Wilhelm Woigk (Institute of Polymer Engineering, FHNW) J. Rion (Bcomp AG) Clemens Dransfeld (University of Applied Sciences and Arts Northwestern Switzerland)

 

Here we aim to study the impregnation of the natural fibres by varying the provided amount of matrix material within the film stacking process. Along with correlating to properties, we show that in some applications higher vf is desired.

PROCESSING BAMBOO FOR STRUCTURAL COMPOSITES: INFLUENCE OF PRESERVATIVE TREATMENTS ON SURFACE AND INTERFACE PROPERTIES

Darshil Upendra Shah (University of Cambridge) Bhavna Sharma (University of Cambridge) Michael H. Ramage (University of Cambridge)

 

Engineered bamboo is being increasingly explored for infrastructure applications. We study the effects of two common preservation treatments, bleaching and steaming, on dynamic surface wettability and adhesive bonding properties of laminated bamboo.

EXPERIMENTAL CHARACTERISATION OF THE IMPACT RESISTANCE OF FLAX FIBRE REINFORCED COMPOSITE LAMINATES

Karthik Ram Ramakrishnan (Ecole des Mines d'Alès) Stéphane Corn (Ecole des Mines d'Alès) Nicolas Le Moigne (Ecole des Mines d'Alès) Pierre Slangen (Ecole des Mines d'Alès) Anne Bergeret (Ecole des Mines d'Alès)

 

The impact resistance of biocomposites made of commingled flax and polypropylene fibres is investigated. The different modes of damage and the critical energy for penetration were identified. An FE model was also developed to simulate the response.

INFLUENCE OF FIBRE LOADING, FIBRE LENGTH, FIBRE ORIENTATION AND VOIDS ON THE CHARACTERISTICS OF COMPRESSION AND INJECTION MOULDED CELLULOSE FIBRE-REINFORCED POLYLACTIDE (PLA) COMPOSITES

Nina Graupner (University of Applied Sciences Bremen ) Jörg Müssig (University of Applied Sciences Bremen )

 

Focus of this study is the investigation of the influences of fibre loading, fibre orientation, fibre length and voids on the mechanical characteristics of compression and injection moulded lyocell fibre-reinforced polylactide (PLA) composites.
