Centrifugal-manufactured GFRP pipes are widely used today as lighting and low-power transmission poles due to their lightweight, high electrical insulation, low cost, corrosion resistance. Despite these advantages, suffer deflection problems elastic shear moduli values. In order overcome this disadvantage, three techniques were suggested control the lateral of poles: an extended internal steel ...

This paper reports an experimental study on the behavior and shear strength of concrete beams reinforced with longitudinal GFRP bars mixed sea water. In order to evaluate how much contributes resistance, seven were tested in bending. Similar size strength, longitudinally glass fiber-reinforced polymer bars; however, they did not even have reinforcement. The beams, which measured 3,100 mm length...

Glass fibre reinforced plastic (GFRP) is considered as structure support and insulating material for the new superconducting FAIR magnets. GFRP (G11) is a composite material consisting of woven glass fibres (volume fraction ~50 %) and cured polymer resin (e.g. amine-cured epoxy). The material will be exposed to cryogenic temperatures, high radiation levels and dynamic mechanical loads (Lorentzi...

Embedding FBG strain sensors within a GFRP sandwich composite material allows early detection of internal defects. However, the sensors need to survive the manufacturing process to provide this capability. Vacuum infusion is commonly used to manufacture GFRP sandwich composite materials but, it needs to be modified to accommodate the embedding process. A stage by stage procedure is demonstrated...

This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...
