O presente trabalho surge no âmbito de um estudo em que foram desenvolvidos varões de compósito entrançados (BCRs) piezoresistivos através da incorporação de um filamento de fibra de vidro impregnado com nanotubos de carbono (CNTs). Diferentes concentrações mássicas de CNTs [0%, 0,5%, 1%, 1,5%, 2% e 2,5%] foram dispersas em formulações poliméricas de resina epóxi e ácido polilático (PLA). Estas formulações fora...
The present work arises from a study in which piezoresistive braided composite rods (BCRs) were developed by incorporating a glass fibre filament impregnated with carbon nanotubes (CNTs). Different mass concentrations of CNTs [0%, 0.5%, 1%, 1.5%, 2% and 2.5%] were dispersed in epoxy resin and polylactic acid (PLA) polymer formulations. These formulations were then used to impregnate the glass fibre filaments wi...
In this paper an experimental work is presented which main objective is the evaluation of the influence of different percentages of waste fibrous materials usage on the performance of fiberreinforced mortars. Moreover, the influence of binder type is evaluated. Therefore mortars were produced with two different binders – cement and powder hydrated lime. Mortars performance evaluation was carried out through flo...

Enhancing the performance and lightness of different structures has already been achieved by the employment of fibre reinforced composite materials. Nowadays, a new challenging perspective is being given to these materials by the inclusion of non-metallic conductive components. This emerging technology will lead to multifunctional composites with possible applications in structural health monitoring and traffic...
