“…Furthermore, as is clear from [3,4], most research on bonded PFRP joints has been concerned with their behaviour in tension. Flexural behaviour of bonded PFRP joints remains to be addressed.…”

Abstract. Three Pultruded Fibre Reinforced Polymer (PFRP) 152 x 152 x 6.4mm Wide Flange (WF) beams were fabricated with a central two-plate splice joint. The 6.4mm thick PFRP splice plates were 210, 410 and 610mm long. Each beam was tested in symmetric four-point bending about its major and minor-axis and deflections, rotations and surface strains were recorded. Beam transverse stiffnesses, support rotations and splice rotational stiffnesses were quantified and compared with theoretical predictions. Predicted deflections were 3.5% to 18.5% larger and support rotations were 10% smaller to 14.2% larger than the experimental values. Splice end rotations were generally poorly predicted.

“…Despite the existence of useful information on bolted tension and beam-to-column joints [1,2] and bonded tension joints [3,4], improved understanding of the behaviour of PFRP joints is still required. This is mainly because PFRPs are orthotropic elastic brittle materials with low throughthickness strength.…”

“…Regarding to the adhesively-boned joint, lots of researches focus on mechanical behaviours of adhesively-bonded joints have been conducted in aerospace engineering, but the results cannot be directly inherited to civil infrastructures, due to the essential differences: bond geometries (adhesive and adherend thicknesses), fabrication processes, loading, curing conditions and service environment. Recently, some researches [5][6][7] were conducted for civil engineering applications, focusing on the mechanical performance of adhesively bonded single-lap joints and double-lap joints. These adhesive joints composed of pultruded GFRP composite profiles glued by epoxy adhesives.…”

SummaryDue to various advantages of Fibre-Reinforced Polymer (FRP) decks, the FRP to steel composite bridge system is being increasingly used in new bridge structures as well as rehabilitation projects for old bridges. This paper focuses on the mechanical behaviours and failure modes of the adhesively-bonded joins between FRP sandwich decks and steel girders. The adhesively-bonded joints were experimentally investigated under tensile and shear loading. Further comparison on failure modes confirmed that the surface pretreatment can improve the bonding quality between FRP composites and adhesive layer, and correspondingly increase the load-carrying capacity of adhesive joints.

“…CFRP composites can be processed by a variety of methods but the most appealing ones are out-of-autoclave processes that can ensure high quality products at minimum cost and high production rates such as vacuum assisted resin transfer molding (VARTM). CFRP composites are used in various applications including offshore wind turbines, bridges, buildings, other large civil engineering structures, ships and aerospace [1][2][3][4][5][6]. Due to their size, it is not practical to fabricate or transport these as complete structures.…”

Abstract. The objective of this study is to improve the mechanical performance of carbon fiber reinforced polymer (CFRP) adhesive joints, called 'laminated joints'. The laminated joints are made by stacking two dry carbon fiber fabric halves together and molding using vacuum-assisted resin transfer molding (VARTM) process. An improved design of this joint was fabricated by overlapping the two half fabrics and adding extra carbon fiber fabric pieces. Four joints are considered in this work: a conventional laminated joint, two laminated joints with overlap, and a multiple-covers laminated joint. The composite joints are characterized in terms of static flexural and impact strength and fatigue performance. In addition, post-fracture analysis is performed using optical microscopy to identify the dependence of failure modes and its propagation in composite joints.
