The article presents the milled surface quality of Uni-Directional Carbon Fibre Reinforced Polymer (UD-CFRP) composites from Taguchi’s and grey relational analysis. novelty is demonstrating possibility detecting defects in polymer during milling using SEM material used for this study UD-CFRP composite laminates made by hand-layup process. All operations were carried out a solid tungsten carbide...

With the gradual application of composite materials to ships and offshore structures, structural strength composites that can replace steel should be explored. In this study, mechanical bearing failure modes a composite-to-metal joining structure connected by mechanically fastened joints were experimentally analyzed. The effects fiber tensile stress concentration on static structures investigat...

For the high strength, corrosion resistance, and good stability, carbon fiber–reinforced polymer (CFRP) composites have been made into pipes to transfer gasses oils in subsea environment. Structural performance of CFRP composite is particularly important sustain regular operation delivery system. To obtain in-field behavior pipes, quasi-distributed optical fiber sensing techniques are developed...

The objective of this study is to conduct a finite-element (FE) numerical assess the effect size on shear resistance reinforced concrete (RC) beams strengthened in with externally bonded carbon fibre-reinforced polymer (EB-CFRP). Although few experimental studies have been done, there still lack FE that consider effect. Experimental tests are time-consuming and costly cannot capture all complex...

Some of the advantages that results from the structural strengthening of concrete slabs using prestressed fiber reinforced polymer (FRP) systems are as follows: the prestressed FRP delays the formation and propagation of cracks, and both the serviceability and the flexural capacity are increased. In this research program, the flexural performance of a concrete slab strengthened with a three-sta...

The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bar...

In the current study, the failure behavior of retrofitted steel structures was studied experimentally and theoretically with steel/CFRP double strap joints (DSJs) under quasi-static tensile loading. A series of DSJs with different bonding lengths are also considered and examined to experimentally assess the effective bond length. To predict the failure load values of the tested specimens, a new...

This work investigates a unique technique to join aluminum (Al) and magnesium (Mg) alloys carbon fiber reinforced polymer (CFRP) composites without the use of adhesives or mechanical fasteners. The joints were made using an overcasting where molten cast around high pressure die casting method. Rapid cooling during allowed composite be embedded inside metal causing any gross damage former even t...
