This paper investigates the deterioration of reinforced concrete with carbon fiber reinforced polymer (CFRP) anode after polarization. The steel in the concrete was first subjected to accelerated corrosion to various extents. Then, a polarization test was performed with the external attached CFRP as the anode and the steel reinforcement as the cathode. Carbon fiber reinforced mortar and conduct...

The incorporation of composite CFRP in wind turbine blades to allow for longer and lighter blades challenges the efficiency of their lightning protection system. The electrical anisotropy of CFRP materials is a key factor and affects their performance. The present study investigates the influence of adding Graphene Oxide (GO) nanoparticles to CFRP as a mean to improve their electrical conductiv...

The paper presents the application of a novel fast numerical tool, based on Generalised Beam Theory (GBT), to perform buckling and post-buckling analyses of laminated CFRP panels. GBT is a beam theory developed for prismatic thinwalled members (e.g., columns, beams or panels), which takes into account both global and local deformations. One of its main features is the fact that the cross-sectio...

BACKGROUND Cardiac positron emission tomography (PET) can lead to flow impairment quantification using PET coronary flow reserve (CFRp: ratio of stress flow to rest flow) and is superior to the current standard, single-photon emission computed tomography. In this study, our first aim was to assess the benefit of CFRp in place of invasive CFR (CFRi) by comparing the correlations of each of the i...

cfrp composites have unique application qualities such as high resistance and durability to environmental conditions, having relatively low weight and easy to install in strengthening concrete structure elements. the brackets should be strengthen sufficiently if they are not calculated and implemented well. application of the cfrp is one of the methods for such purposes. the study involves usin...

Introduction: Carbon fibre-reinforced polymers (CFRP) are being investigated for the next generation of arthroplastic devices. Their mechanical similarities with bone make them ideal for load bearing implants. Previous attempts at using CFRP have failed due to the lack of osseointegration with bone. Treatments to increase surface roughness and topography have shown to affect the attachment and ...

Reinforced concrete (RC) beams may require flexural strengthening due to the corrosion of reinforcing bars or changes in design load. The near surface mounted (NSM) and externally bonded (EB) techniques, using either glass carbon fibre-reinforced polymer (GFRP CFRP) composites, are used for deficient RC beams. However, strengthened with both techniques susceptible debonding failure FRP composit...

Strut-and-tie model (STM) method evolved as one of the most useful designs for shear critical structures and discontinuity regions (D-regions). It provides widespread applications in the design of deep beams as recommended by many codes. The estimation of bottle-shaped strut dimensions, as a main constituent of STM, is essential in design calculations. The application of carbon fibre reinforced...

Previous works have established the response and failure behaviour of hybrid (CFRP-GFRP) laminates when subjected to a wide range destabilising loads. However, date no focused on plates with cut-outs under shear loading quantified influence selective laminate shapes hybridisation their post-buckling response. Herein, plate collapse novel X-braced twill woven containing large circular cut-out (d...
