Offshore structures are exposed to risks of vessel collisions and impacts from dropped objects. Tubular members extensively used in offshore construction, thus, there is scope investigate their crashworthiness behaviour. Aluminium, glass fibre reinforced polymer (GFRP) hybrid aluminium/GFRP circular tube specimens were fabricated then tested under quasi-static dynamic axial loading conditions. ...

Several past studies have shown the use of glass fibre-reinforced polymer (GFRP) bars to alleviate reinforced steel rusting issue in different concrete structures. However, practise GFRP columns has not yet achieved a sufficient confidence level due lack theoretical model found literature. The objective current study is introduce novel prediction for axial capability made with GFRP. For this pu...

In this study, a multi-spot laser scanning thermography (MLST) system is developed for automated, rapid and long-range inspection of delamination in composite structures. First, thermal waves are generated by scanning a multi-spot laser beam over a target composite structure, and the corresponding thermal waves are measured by using an infrared (IR) camera. Then a thermal image processing algor...

Ageing concrete infrastructures are known to be facing deterioration, especially regarding the corrosion of their reinforcing steel. As a solution, glass fibre-reinforced plastic (GFRP) bars now considered reinforcement alternative conventional steel, and design codes exist for designing GFRP-RC structures. However, there is need improve on addressing limited yield in GFRPs. Consequently, it su...

Abstract Glass fibers reinforced polymer (GFRP) were used to longitudinally and transversally 12 columns while the other 4 with steel or GFRP as reference specimens. This research dealt several parameters under different loading conditions, such reinforcing material spacing between ties. study aims find out ability of bear loads. In addition, investigate mode failure in these their appropriaten...

The challenges of machining, particularly milling, glass fibre-reinforced polymer (GFRP) composites are their abrasiveness (which lead to excessive tool wear) and susceptible to workpiece damage when improper machining parameters are used. It is imperative that the condition of cutting tool being monitored during the machining process of GFRP composites so as to re-compensating the effect of to...

In this work, a theoretical approach is proposed for estimating the minimum and maximum reinforcement ratios hybrid glass fiber reinforced polymer (GFRP)/steel-reinforced concrete beams to prevent sudden brittle failure as well compression of before tension reinforcements. Equilibrium equations were used develop method determining GFRP/steel ratio. A ratio was also developed based on equilibriu...

In this study, we report the effect of sizing glass fibres (GFs) with tetramethylpiperidine-1-oxyl (TEMPO)-mediated cellulose nanocrystals (t-CNC) to improve interfacial mechanical performance fibre reinforced polymer composites (GFRP). These nanoparticles are introduced at different concentrations yield a coating t-CNCs which (1) sparsely deposited low concentrations, and (2) uniformly self-as...
