Abstract
Fiber-reinforced polymer (FRP) matrix materials are quickly being investigated for application in concrete construction repair, reinforcement, and refurbishment. The technology has progressed to the point that its future acceptance is mainly reliant on the availability of established design guidelines based on recognized performance criteria, as well as the cost competitiveness of these technologies in contrast to conventional rehabilitation methods. The goal of this study is to evaluate the different functional grades of adhesives throughout bond length for bonded socket joints of laminated FRP composite pipes. Damage development resistance is high with a functionally graded FRP composite socket joint, as shown. To extend the service life of the structure, the joint designer should use an FRP composite socket joint with a functionally graded adhesive (FGA).
Highlights
Adhesives are a common option for connecting various materials, especially composites and metals, in a number of industries due to their enhanced durability and strength
The following specific conclusions were made based on the findings and observations about the damage in the Fiber-reinforced polymer (FRP) composite socket joint: 1. Case I investigates the impact of functionally graded adhesive (FGA) on socket junctures failures in laminated FRP tube
In Case I, using Functionally graded modified (FGM) adhesive with an asymmetric function is recommended since it produces superior outcomes
Summary
Adhesives are a common option for connecting various materials, especially composites and metals, in a number of industries due to their enhanced durability and strength. Glued composite tube junctions are extensively utilized to couple different composite structures in the aviation and energy sectors. Their low cost of production and high mechanical efficiency structures made of pipes are crucial in the energy and construction industries. Butt-and-strap connections, heat-activated coupling joints, and flanged joints are the most common joining methods for composite tubes [1]. The fundamental architecture of all permanent couplings is the same: two pipe lengths to be connected, a coupler to transmit load to the junction, and a mechanism to transmit force through the tube to the coupler. An overview of bonded pipe connections may assist you in comprehending the essential features of all three kinds of bonded pipe connections
