Shady Attia,Polyvios Eleftheriou,Flouris Xeni,Rodolphe Morlot,Christophe Menezo,V. Kostopoulos,Maria Betsi,Iakovos Kalaitzoglou,Lorenzo Pagliano,Maurizio Cellura,Manuela Guedes de Almeida,Marco António Pedrosa Santos Ferreira,Tudor Baracu,Viorel Badescu,Ruxandra Crutescu,Juan Maria Hidalgo-Betanzos +15 more
TL;DR: In this paper, a cross-comparative study of the societal and technical barriers of nZEB implementation in 7 Southern European countries is presented, and the authors provide recommendations for actions to shift the identified gaps into opportunities for future development of climate adaptive high performance buildings.

Resistive heating of multidirectional and unidirectional dry carbon fibre preforms
N. Athanasopoulos,V. Kostopoulos +1 more
TL;DR: In this article, the electrical conductivity tensor of continuous carbon fiber (CF) layers is expressed by a second order tensor and the generated heat (Joule effect) can be determined.

Multistage fatigue life monitoring on carbon fibre reinforced polymers enhanced with multiwall carbon nanotubes
Antonios Vavouliotis,P. Karapappas,Theodoros Loutas,T. Voyatzi,Alkiviadis S. Paipetis,V. Kostopoulos +5 more
TL;DR: In this article, CNTs were used as modifiers of the epoxy matrix of quasi-isotropic carbon fiber reinforced laminates, which exhibited superior fatigue properties and demonstrated the full potential of the material to be used as an integrated sensor to monitor the fatigue life.

Sensing strain and damage in polyurethane-MWCNT nano-composite foams using electrical measurements
TL;DR: In this article, the damage identification in polymeric foams through the monitoring of the electrical resistance of the system was dealt with by using micro-structural observa- tions.

Numerical investigation and experimental verification of the Joule heating effect of polyacrylonitrile-based carbon fiber tows under high vacuum conditions
TL;DR: In this article, the authors investigated the Joule heating effect of two types of carbon fiber to investigate the effect of electric current passing through a conductor, and found that when electric current passes through a conductive material, heat is generated.
