Abstract

In this study, an effort was made to develop an experimental protocol to study the effects of accelerated ageing on GFRP (Glass Fiber-Reinforced Polymer) grids. The physic-mechanical properties of different types of glass FRP grids were investigated. GFRP specimens were subjected to environmental agents including freeze-thaw, high relative humidity, high temperature. Mechanical and physical tests were used to measure the retained properties and to observe the causes of damage and strength reduction. The experimental data showed that resin properties may strongly influence the durability of FRP reinforcement, environmental combined cycles did not take to significant damage of conditioned specimens; GFRP grids are sensitive to alkaline attack when resin does not provide adequate protection to fibers.
