GREEN COMPOSITES: CHALLENGES TO REACH HIGH PERFORMANCE COMPONENTS

Silvia Lloret Pertegás (Montanuniversitaet Leoben) A. Anusic (Montanuniversitaet Leoben) Katharina Resch (Montanuniversitaet Leoben) Ralf Schledjewski (Montanuniversitaet Leoben)

 

The major focus is on Biocomposites' processability. Challenges in processing are analyzed. The final performance of the bio-based composite is compared with conventional systems, i.e. epoxy-glass.

MECHANICAL PROPERTIES OF HEMP FIBRE/EPOXY COMPOSITES - INFLUENCE OF FIBRE CHEMICAL TREATMENTS

Raffaele Sepe (Second University of Naples) Flavia Bollino (Second University of Naples) Angelo Ceparano (Second University of Naples) Giuseppe Lamanna (Second University of Naples)

 

In this paper, tensile and flexural strength of epoxy matrix composite reinforced with woven hemp was studied. Fibre-matrix adhesion was promoted by fibre surface modifications using an alkaline treatment and a silane coupling agent.

SWELLING OF FLAX FIBERS: EFFECT OF A THERMAL TREATMENT ON THEIR DIMENSIONAL STABILITY

Monica Francesca Pucci (EMSE) Pierre-Jacques Liotier (Mines Saint-Etienne) David Seveno (KU Leuven) Carlos Fuentes (KU Leuven) Aart Van Vuure (KU Leuven) Sylvain Drapier (Mines Saint-Etienne)

 

This paper describes how flax fibers were submitted to a thermal treatment to modify their wettability and sensitivity to liquid sorption. Swelling of untreated and treated fibers was measured combining an optical and a tensiometric methods.

TENSILE PROPERTIES OF BOWING NATURAL LFT COMPOSITES

Junji Noda (Yamaguchi University) Kousuke Torii (Yamaguchi University) Syotaro Hiramatsu (Yamaguchi University) Koichi Goda (Yamaguchi University)

 

Natural LFT composites with high Young’s modulus were developed using M-PaRI process. From fiber morphologies, it was confirmed the bowing natural fibers occurred near skin. Young’s modulus prediction based on FEM was conducted and discussed.

ANISOTROPIC NANOSTRUCTURE INSPIRED BY NATURE FOR ENERGY ABSORBING COMPOSITE INTERFACES

Francois De Luca (Imperial College London) Alexander Bismarck (University of Vienna) Milo Shaffer (Imperial College London)

 

A nacre-nanomimetic with the classic "brick-and-mortar" structure of natural nacre was assembled. Therefore, an increase in the absolute interface density enabled for substantial plastic deformation.

EFFECT OF EPOXY-GNPS NANOCOMPOSITES COATINGS ON THE WEAR BEHAVIOUR OF ALUMINIUM

Monica Campo (Universidad Rey Juan Carlos) A. Jimenez-Suarez (Universidad Rey Juan Carlos) A. Urena (Universidad Rey Juan Carlos)

 

Epoxy coatings, reinforced with differents graphene nanoplates percentages (0–10 wt%), have been deposited on aluminium substrates to improve its wear behavior. The wear of aluminium significantly improves due to the lubricant effect of graphene.
