This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...

Abstract Carbon fiber reinforced polymer (CFRP) is widely used in high-tech industries because of its interesting characteristics and properties. This material presents good strength stiffness, relatively low density, high damping ability, dimensional stability, corrosion resistance. However, the machinability composite materials complex matrix/fiber interface, being a challenging machining mat...

The utilization of carbonaceous reinforcement-based polymer matrix composites in structural applications has become a hot topic composite research. Although conventional carbon fiber-reinforced (CFRPs) have revolutionized the industry by offering unparalleled features, they are often plagued with weak interface and lack toughness. However, promising aspects fiber-based fiber hybrid hierarchical...

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...

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...

Carbonfiber-reinforced polymer (CFRP) composites are frequently utilized in the repair and reinforcement of reinforced concrete members because they more corrosion-resistant, durable, flexible than commonly used materials like steel plates. Many studies have demonstrated that use CFRP as an internal strengthening material has a substantial impact on shear capacity RC beams. This research looks ...
