“…Pultruded GFRP profile used in infrastructure usually has a large thickness and its ply thickness is not as precise as that in aerospace application. A practical method to predict ply thickness has been proposed by authors [30], the GFRP plate’s predicted ply thickness is summarized in Table 4.…”

In order to evaluate the shear performance of sand-coated glass fiber-reinforced polymer (GFRP) perforated connectors (SCGPC) embedded in concrete, 8 pull-out tests were conducted. Finite element (FE) analysis considering GFRP failure and cohesion between GFRP and concrete of SCGPC were conducted for parametric analysis. Effects of surface treatment, hole’s radius, embedment length, and multi holes were examined. The test and theoretical analysis revealed that the strength of SCGPC is considerably larger than GFRP Perforated Connector (GPC). The stiffness of SCGPC is determined by the adhesion between concrete and GFRP. When GFRP plate’s thickness is less than the critical thickness, the embedment length plays a major role in the strength of SCGPC. When embedment length is less than the effective bond length, the shear strength of SCGPC is governed by both the adhesion and GPC’s shear capacity; otherwise, the strength of SCGPC is governed by the adhesion strength. Furthermore, an empirical equation was suggested to predict the shear strength of SCGPC. The equation involves the failure mechanism of both bond and GPC and deals the strength of SCGPC into two ranges according to the embedment length. Good agreement was achieved between the strength prediction by the suggested equation and the parametric analysis result.

“…Most recently, a novel hybrid GFRP-concrete deck system with composite T-shaped perforated rib connectors was developed by Zuo et al (Figure 13) [39,40]. ere were two other connection mechanisms except for the sandcoated GFRP plate surface: one was shear and uplift effects of GFRP T-shaped ribs, which was similar to headed studs and the other was formed by the penetrating bars through the holes in GFRP T-shaped perforated ribs.…”

The state-of-the-art review of hybrid GFRP-concrete systems for bridge decks is presented in this study. Previous research on the experimental work, analytical modeling, and field application on hybrid GFRP-concrete deck systems are presented, along with a variety of deck systems are discussed. Then, seven typical types of connection technology between FRP and concrete are introduced and compared. Besides, the current progress on the performance of shear connections via beam tests, pushout tests, and pullout tests are probed, respectively. Finally, general conclusions are made, identifying the need for future research.

“…Therefore, the lightweight design of the leaf spring is of great concern in the automobile industry [1,[8][9][10]. The fiber-reinforced polymer (FRP) composite possesses outstanding properties such as high stiffness and strength, low specific mass, and corrosion resistance, in combination with a flexible design, which has emerged as the viable candidate for the weight reduction applications without losing performance in terms of load-carrying capacity or stiffness [11][12][13][14][15][16][17][18][19][20][21]. Therefore, the introduction of composite materials enables the weight reduction in the leaf spring, which leads to a better riding performance of the vehicle as well as the reduction in vehicle cost [22].…”

Due to the high load-bearing capacity and light weight, composite leaf spring with variable width and variable thickness has been increasingly used in the automobile industry to replace the conventional steel leaf spring with a heavy weight. The optimum structural design of composite leaf spring is particularly favorable for the weight reduction. In this study, an effective algorithm is developed for structural optimization of composite leaf spring. The mechanical performance of composite leaf spring with designed dimensions is characterized using a combined experimental and computational approach. Specifically, the composite leaf spring with variable width and variable thickness was prepared using the filament winding process, and the three-dimensional finite element (FE) model of the designed composite leaf spring is developed. The experimental sample and FE model of composite leaf spring are tested under the three-point bending method. From experimental and simulation results, it is shown that the bending stiffness of the designed leaf spring meets the design requirement in the automotive industry, while the results of stress calculation along all directions meet the requirements of material strength requirement. The developed algorithm contributes to the design method for optimizing the stiffness and strength performance of the composite leaf spring.
