This research paper compares the thermal conductivity and thermal expansion coefficients of glass fiber reinforced epoxy composite laminates (GFRP laminates) made using the Hand layup technique. The composite laminates were fabricated by filling with varying concentrations of fly ash, stone powder, aluminium oxide (Al2O3), magnesium hydroxide (Mg (OH)2), Silicon carbide particles(SiC) and hemat...

At present, design and construction of all-FRP structures with the use GFRP are developing. All-FRP frame bolted connections to form nodes between elements, particularly steel bolts. This research focuses on FRP pultruded plates instead chords webs. Frame formed by adjoining elements at different angles through gusset plates. In accordance literature analysis, a small number tests have been car...

Glass fiber-reinforced polymer (GFRP) ship structures have hull plate thicknesses of 10 mm or more and are fabricated using a higher proportion resin matrix systems than E-glass fiber reinforcements. Therefore, GFRP is classified as highly attenuative material, this characteristic major cause large errors in ultrasonic nondestructive testing for quality inspections. In study, considering the af...

Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...

Glass fiber-reinforced polymers (GFRPs) have attracted significant attention as structural materials because of their high fatigue resistance, corrosion strength, and stiffness. This study examined the effect elevated temperatures (150, 250, 350, 450oC) on microstructural mechanical properties GFRP plates. The number bubbles increased firing temperature increased, burst at 250oC or higher, form...

BACKGROUND AND PURPOSE 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4 ) is an essential cofactor for nitric oxide biosynthesis. Substantial clinical evidence indicates that intravenous BH4 restores vascular function in patients. Unfortunately, oral BH4 has limited efficacy. Therefore, orally bioavailable pharmacological activators of endogenous BH4 biosynthesis hold significant therapeutic poten...

The article presents the methodology for finding material damping capacity at higher frequency and lower amplitudes. Lamb wave dispersion theory is used for finding the damping capacity of composite material which is used at extensively high frequency applications. The method has been implemented on carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) plates. The Lam...

Fiber reinforced polymer materials are continuing to show great promise for using strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing, because of their light weight, resistant to corrosion and high strength. The main aim of this study is to investigate the flexural characteristic of RC beams using GFRP sheets and strips. This pap...
