In steel fiber-reinforced composites materials, fiber and matrix are bonded together through a weak interface. The study of this interfacial behavior is important for understanding the mechanical such composites. Moreover, with outcome new materials improved properties advanced cement matrices, in case reinforced self-compacting concrete, fiber/matrix interface assumes interest. present work, experimental results both straight hooked-end fibers pullout tests on concrete medium presented...
In recent years, a strengthening technique based on near-surface mounted (NSM) laminate strips of carbon-fiber-reinforced polymer (CFRP) has been used to increase the load-carrying capacity concrete and masonry structures by introducing into precut grooves cover elements be strengthened. The high experimentally derived levels strength efficacy with columns, beams, panels have presented NSM as viable promising technique. This practice requires no surface preparation work and, after cutting...
This paper presents the principle and application of an innovative anchorage technique for prestressed carbon fiber–reinforced polymer (CFRP) strips in structural strengthening. Additionally, large-scale static loading tests retrofitted concrete beams are shown. The gradient anchorage, based on adhesive's ability to undergo accelerated curing at high temperatures, consists a purely concrete-adhesive strip connection without any mechanical devices, such as bolts or plates. In first step, this...
The development of new adhesives has allowed to expand the application bonding into most diverse industrial fields. This review article presents commonly used experimental methods for investigation mechanical performance adhesively bonded joints in aerospace, wind energy, automotive and civil engineering sectors. In these sectors, due their excellent intrinsic properties, composite materials are often along with conventional such as steel, concrete aluminium. this context, limitations that...
Near-surface mounted (NSM) carbon fiber reinforced polymer (CFRP) laminate strips are used to increase the load-carrying capacity of concrete structures. This is done by inserting CFRP into slits made in cover elements be strengthened and gluing with an epoxy adhesive. In several cases NSM technique has substantial advantages when compared externally bonded laminates. To assess bond behavior between under monotonic cyclic loading, experimental program was carried out based on a series...
This work investigates the quasi-static, low-cycle and fatigue behavior of hybrid glass/ultra-high modulus carbon (GC) low modulus/ /high (CC) fiber composites. These pseudo-ductile unidirectional interlayer hybrids are a new type composites whose potential is not yet fully understood, particularly under cyclic/fatigue loading. Different test methods (digital image correlation, video extensometer thermal camera) were used to record evolution strain, damage temperature during The results...
The durability of bond between carbon fibre-reinforced polymer (CFRP) laminates and concrete with the externally bonded reinforcement (EBR) technique was investigated under real-time field exposure (RTFE) accelerated ageing. experimental program, over two years, includes four outdoor environments inducing carbonation, freeze–thaw attack, extreme temperatures, airborne chlorides from ocean. A laboratory environment (20 °C/55% RH) used as reference environment. Additionally, a water-immersion...
Externally bonded fibre reinforced polymer (FRP) reinforcements have been widely used for upgrading the shear resistance of concrete (RC) structures. This technique has studied and numerous analytical models currently exist to predict contribution FRP RC beams. In this study, some most well-known recommended in guidelines (including fib bulletin 90, CNR-DT 200 R1/2013, ACI 440.2R-17) are selected, their predictive performance assessed using a large database 344 beams compiled from published...
