ON THE MULTI-FUNCTIONAL BEHAVIOR OF GRAPHENE BASED NANO-REINFORCED POLYMERS

Stavros Tsantzalis (University of Patras) Christina Kostagiannakopoulou (University of Patras) George Sotiriadis (University of Patras) Vassilis Kostopoulos (University of Patras)

 

The objective of present work is to investigate the influence of Graphene Nano-Platelets on the multi-functionality of nano-reinforced epoxy polymers. Thermal conductivity measurements, thermo-mechanical and mechanical tests were performed.

STRENGTHENING MECHANISM OF GRAPHENE/METAL NANOLAYERED COMPOSITES

Zhenyu Yang (Beihang University) Dandan Wang (Beihang University) Jian Sun (Beihang University) Zixing Lu (Institute of Soild Mechanics, Beihang University)

 

MD simulation was employed to investigate the deformation mechanisms of graphene/metal nanowires with layered structures. The strengthening mechanisms of nanolayered composites nanowires are revealed as dislocations blocked by graphene layers.

IMPACT PROPERTIES OF GRAPHENE MODIFIED POLYMERS AND COMPRESSION AFTER IMPACT (CAI) PROPERTIES OF GRAPHENE MODIFIED CFRPS

Christina Kostagiannakopoulou (University of Patras) Stavros Tsantzalis (University of Patras) George Sotiriadis (University of Patras) Vassilis Kostopoulos (University of Patras)

 

Present study investigates the influence of GNPs on the impact behavior of nano-reinforced polymers and CFRP laminates. Charpy tests reveal that the introduction of GNPs into the polymer improved 50% the impact resistance of the reference material.
