The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...

This study investigates the impact of accelerated aging conditions on the long-term flexural behavior and ductility of reinforced concrete (RC) members with glass fiber-reinforced polymer (GFRP) bars (RC-GFRP specimen) and steel bars (RC-steel specimen). A total of thirty six specimens were designed with different amounts of reinforcement with three types of reinforcing bars (i.e., helically wr...

Abstract This work investigated effect of glass fibre fabric structures, feedstock feed rate and screen size on specific shredding energy reinforced plastics (GFRP) waste via a two-level factorial design experiment study. Four types structure, i.e. unidirectional (UD), biaxial (BIAX), triaxial (TRIAX) chopped strand mat (CSM), were impregnated separately with unsaturated polyester resin to manu...

GTP cyclohydrolase I feedback regulatory protein (GFRP) is a 9.7-kDa protein regulating GTP cyclohydrolase I activity in dependence of tetrahydrobiopterin and phenylalanine concentrations, thus enabling stimulation of tetrahydrobiopterin biosynthesis by phenylalanine to ensure its efficient metabolism by phenylalanine hydroxylase. Here, we were interested in regulation of GFRP expression by pro...

Dynamic loading on composite components may induce damages such as cracks, delaminations, etc. and development of an early damage detection technique for delaminations is one the most important aspects in ensuring integrity safety components. The presence composites reduces its stiffness further changes dynamic behaviour structures. As loss leads to natural frequencies, mode shapes, other struc...

Glass fiber reinforced polymer (GFRP) pultruded profiles are being increasingly used in civil engineering applications. Although they offer several advantages over traditional materials, such as high strength, lightness and non-corrodibility, GFRP profiles present low elasticity and shear moduli, which together with their slender walls makes them very prone to buckling phenomena. Several previo...
