CNT-grafted glass fibers as a smart tool for epoxy cure monitoring, UV-sensing and thermal energy harvesting in model composites
(2016)A 'hierarchical' reinforcement of glass fibers (GFs) chemically grafted with multiwall carbon nanotubes (MWCNTs) has been utilized for epoxy cure monitoring, UV-sensing, and thermal energy harvesting in model composites. ... -
Development of wood composites from recycled fibres bonded with magnesium lignosulfonate
(2020)The potential of producing ecofriendly composites from industrial waste fibres, bonded with magnesium lignosulfonate, a lignin-based formaldehyde-free adhesive, was investigated in this work. Composites were produced in ... -
Eco-friendly, high-density fiberboards bonded with urea-formaldehyde and ammonium lignosulfonate

(2020)Background and objective: In this work, the effect of the micropolar fluid parameters on the hydraulic permeability of fibrous biomaterials comprised of square arrays of undirectional fibrils is investigated. Methods: ... -
The effect of partial substitution of polyphosphates by aluminium hydroxide and borates on the technological and fire properties of medium density fibreboard
(2022)Aim of this study was to evaluate the effect of aluminium hydroxide and borates, separately or combined with ammonium polyphosphate (APP), upon the technological and fire properties of medium density fibreboard (MDF). Fire ... -
Effectiveness of different confining configurations of FRP jackets for concrete columns
(2019)This paper presents the results of an experimental investigation on the compressive strength of small scale concentrically axially loaded fiber-reinforced polymer (FRP) confined plain concrete columns, with cylinder concrete ... -
Environmental aspects of fiber crops cultivation and use
(2015)Bioenergy and biomaterials from fiber crops are regarded as promising substitutes for conventional ones, considering the growing concern about oil and other non-renewable resources depletion and the environmental impacts ... -
Evidence of functional deficits at the single muscle fiber level in experimentally-induced renal insufficiency
(2019)Chronic kidney disease patients present with metabolic and functional muscle abnormalities, called uremic myopathy, whose mechanisms have not yet been fully elucidated. We investigated whether chronic renal insufficiency ... -
Fiber plasticity and loss of ellipticity in soft composites under non-monotonic loading
(2022)In this work, we relate fiber plasticity in soft composites to the loss of ellipticity of the governing equations of equilibrium of a composite under non-monotonic uniaxial loading. The loss of ellipticity strongly indicates ... -
Fiber Reinforced Polymer (FRP) Confined Circular Columns: Compressive Strength Assessment
(2020)Fiber Reinforced Polymer (FRP) composites may be successfully used in numerous structural strengthening applications. One of these applications is as a confining material for reinforced concrete structural elements. Research ... -
Linking Distributed and Integrated Fiber-Optic Sensing
(2022)Distributed Acoustic Sensing (DAS) has become a popular method of observing seismic wavefields: backscattered pulses of light reveal strains or strain rates at any location along a fiber-optic cable. In contrast, a few ... -
Medium-density fibreboards bonded with phenol-formaldehyde resin and calcium lignosulfonate as an eco-friendly additive
(2021)The potential of addition of calcium lignosulfonate as an eco-friendly additive with a phenol-formaldehyde (PF) resin, at different ratios, to produce medium-density fibreboards (MDF) with acceptable properties, was ... -
Pin-assisted resin infiltration of porous substrates
(2015)We analyze computationally the process of pin-assisted resin infiltration of porous substrates. In such a process, a porous substrate is pulled over a staggered array of stationary pins. A wedge-shaped fluid region forms ... -
Sensitivity kernels for transmission fibre optics
(2022)Fibre-optic sensing based on transmission offer an alternative to scattering-based distributed acoustic sensing (DAS). The ability to interrogate fibres that are thousands of kilometres long opens opportunities for studies ... -
