This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...

Three different laminated composites are used in this study: carbon fiber, woven glass and glass-fiber-reinforced epoxy. The composite laminate structures were fabricated using the hand lay-up technique at room temperature. laminates reinforced with epoxy resin, fibers (CFRP), (GFRP-W), random-orientation (GFRP-R) to obtain eight layers. wear test was performed a pin-on-disc tribometer five loa...

Shape, thickness and stacking sequence optimisation of a damage tolerant hybrid (GFRP-CFRP) composite laminate is performed using the commercial Optistruct solver. The results study are compared to both benchmark non-damage CFRP (without protective surface GFRP plies known as type 1 laminate) traditionally optimised CFRP-GFRP (having X shape 2 laminate), designed tested in previous study. manuf...

Abstract The behavior of eccentrically loaded RC columns strengthened by NSM steel and glass fiber reinforced polymer (GFRP) rebars is investigated in this study. A total six column specimens have been cast study with dimensions (150×150×1200) mm (width × height length). Two are unstrengthened considered as controls, while the other method using bars hybrid GFRP rebars. All tested under concent...

in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...

The present study concentrates on optimization and the effect of machining parameters delamination that occurs during drilling operation pure glass fiber-reinforced polymer (GFRP) composites added GFRP which were developed for resistance to erosion wear. Contribution was investigated by using Taguchi method analysis variance (ANOVA). Relationship between modelled response surface methodology. C...
