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...

The study aimed to explore the possibility of strengthening RC corbels with many techniques. research analyzed behavior under a wide range variables. theoretical consisted twelve models reinforced GFRP bars by steel plate. Finite element analysis ANSYS APDL was used verify five specimens. This deals static nonlinear FE simulation investigate Corbels internally and externally. verification exper...

Two new Chinese species of the leafhopper genus Onukigallia, Onukigallia neoonukiisp. n. from Sichuan and Guangdong Provinces, and Onukigallia tumidasp. n. from Hubei and Hunan Provinces are described and illustrated. A key and an updated checklist with distributions of Onukigallia species are provided.

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...

This study investigates the influences of three types locally available low-cost Fiber Reinforced Polymers (FRP) wraps and two concrete mix designs on axial behavior FRP confined concrete. The experimental program comprised four unconfined (control), glass Matt Strand (GFRP-MS) concrete, Rowing (GFRP-R) carbon (CFRP) specimens with a diameter 150 mm height 300 tested under compression. were pre...
