“…When CFRP elements are in frictional contact with other components and subjected to relative cyclic displacement, their fatigue life can be drastically reduced due to the fretting process that occurs at the material interfaces. In general, the fretting wear performance of FRP laminates depends on many different factors, such as the fibre and matrix materials, the fibre orientation, the sliding direction, the contact pressure on the fretted surface, the amplitude and frequency of the reciprocating motion, the hardness of the contacting material, surface treatments, lubrication, and interfacial temperature conditions [21,22,23,24,25]. As regards the sliding direction specifically, the highest wear resistance occurs when sliding occurs parallel to the fibres, and the lowest for sliding perpendicular to the fibres [26,27,28].…”

Steel cables and suspenders in bridges are at high risk of corrosion-fatigue and in some cases of fretting-fatigue in their anchorages. These factors greatly limit the service stresses of a specific cable system and involve expensive protection measures. In order to investigate the above limitations, the fretting fatigue behaviour of pin-loaded carbon fibre reinforced polymer (CFRP) straps was studied as models for corrosion-resistant bridge suspenders. Two types of straps were tested: small model straps with a sacrificial CFRP ply and large full-scale straps. In a first phase, five fully laminated and carbon pin-loaded CFRP model straps were subjected to an ultimate tensile strength test. Thereafter, and in order to assess their durability, 20 model straps were subjected to a fretting fatigue test, which was successfully passed by 4 straps. An S-N curve was generated for a load ratio of 0.1 and a frequency of 10 Hz. In a second phase, one full-scale strap was tested for its ultimate tensile strength and two full-scale straps were fatigue-tested. The influence of fretting fatigue loading on the residual mechanical properties of the straps was also assessed, and although fretting fatigue represented an important limitation for laminated CFRP straps, it could be shown that the investigated CFRP tension members can compete with the well-established steel suspenders.

“…Such cases arise in bearings, gears, bushes, multi-layer leaf springs, palliatives, bolted, riveted and pinned joints, bearing liners, spline couplings, gripped components, flanges, seals etc. [4,5]. Fretting also contributes to a significant extent in the total wearing mechanisms, though its extent of contribution depends on the operating conditions of the component.…”

Tribo-potential of bi-directionally (BD) reinforced polymer composites is not yet adequately explored especially in low amplitude oscillating wear (LAOW)/fretting wear mode. Hence five composites of Polyetherimide (PEI) containing carbon fabric (plain weave) in the range 40-85 by vol% were developed by impregnation technique followed by compression molding. These composites along with unfilled PEI were evaluated for their LAOW performance on SRV Optimol tester under different loads using ball-on-plate configuration. The performance was compared with that of composite evaluated in earlier work but developed with different processing technique (hand lay up). With increase in load, specific wear rates of all the composites increased while friction coefficient (l) decreased. It was concluded that carbon fabric inclusion in all amounts proved significantly beneficial for improving friction and wear performance and limiting load of PEI. Very high and very low amount of CF (85 and 40 vol%) proved least beneficial from strength and tribo-performance point of view. Composites with moderate amount of CF (65 and 55 vol%) proved most promising with almost similar potential in reducing l and wear rate of PEI. Overall CF in the range of 55-65 vol% appeared to be the optimum range for tailoring the strength properties along with tribo-performance in fretting wear mode. The impregnation technique proved significantly better than the hand lay up technique for enhancement in strength and triboperformance. SEM studies on worn surface proved helpful in understanding wear mechanisms.

Polyethersulfone (PES) composites were developed with carbon fabric (CF). Cold remote nitrogen oxygen plasma (CRNOP) treatment was employed to the CF to incorporate functional groups and promote fibermatrix adhesion. This study includes the effect of PES melt flow index (MFI) on the wettability of CF and its influence on fretting wear performance. Evaluations of fretting wear properties of composites led to the conclusion that the CRNOP treatment proved beneficial to enhance performance properties significantly. Polymer MFI and treatment to CF proved to be the decisive parameters for controlling performance of composites apart from operating parameters. Perforations on the treated carbon fiber, evidently observed by FESEM, improved the fiber-matrix adhesion, and hence the performance properties. Artificial neuron network (ANN) was used for prediction of the wear behavior of composites.
