An investigation was performed by using carbon fiber-reinforced polymer (CFRP) as the anode material in the impressed current cathodic protection (ICCP) system of steel reinforced concrete structures. The service life and performance of CFRP were investigated in simulated ICCP systems with various configurations. Constant current densities were maintained during the tests. No significant degrad...

Carbon fiber-reinforced polymers (CFRPs) can be used in aging infrastructures as a reinforcement because of their excellent mechanical properties, and they also the support maintenance repair work these structures. However, development CFRPs while achieving self-powered damage detection is still challenging. Herein, sodium potassium niobate (KNN) nanoparticle-filled epoxy (KNN–EP) plate was fab...

A new analytical method to predict the torsional capacity and behavior of R.C multi-cell box girders strengthened with carbon fiber reinforced polymer (CFRP) sheets is presented. Modification was done on the Softened Truss Model (STM) in the proposed method; the concrete torsional problem is solved by combining the equilibrium conditions, compatibility conditions and constitutive laws of materi...

INTRODUCTION Carbon fiber reinforced plastic (CFRP) laminates are used in various industrial fields because they have excellent properties in the specific strength and specific stiffness. The CFRP has a potential of weight reduction in the automotive structure which can contribute to the improvement of mileage as well as the reduction of carbon dioxide. On the other hand, the safety issue in ca...

• Self-anchored prestressed CFRP plates without the need for mechanical end anchorage. Significant improvement in bending stiffness, crack width, and load-carrying capacity. Nonlinear finite element analyses of flexural cracks crack-induced debonding plates. This paper presents an innovative method prestressing carbon fibre reinforced polymer (CFRP) used as externally bonded reinforcement stren...

This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...

This paper presents the shear performance of reinforced concrete (RC) beams with Tsection. Different configurations of externally bonded carbon fiber reinforced polymer (CFRP) sheets were used to strengthen the specimens in shear. The experimental program consisted of six full-scale, simply supported beams. One beam was used as a bench mark and five beams were strengthened using different confi...

Owing to high specific strength and designability, unidirectional carbon fiber reinforced polymer (UD-CFRP) has been utilized in numerous fields to replace conventional metal materials. Post machining processes are always required for UD-CFRP to achieve dimensional tolerance and assembly specifications. Due to inhomogeneity and anisotropy, UD-CFRP differs greatly from metal materials in machini...

This study focusses on the influence of different cooling strategies process temperatures and chip transport quality in one-shot drilling CFRP/Al-stacks. In addition to maximum both individual stack components, temperature changes CFRP material due hot aluminium interactions are analysed. The following compared: compressed air through tool, cryogenic CO 2 at bore exit as well combination both. ...
