“…No significant failure of the core CFRP was seen when the cross-section morphology of rod was observed after fatigue. A similar failure mode was reported in the research by Kar et al 32 By comparison, local fatigue failure was observed after immersion in the present study. As in the above analysis, cracking of the resin and fibre/resin interface after immersion was delayed during fatigue owing to postcuring of the resin.…”

A pultruded carbon fibre core (CFC) and glass fibre shell (GFS) hybrid fiber reinforced polymer (HFRP) rod with the diameter of 19 mm was developed. It was kept immersed in water in a self‐designed pressure chamber device with adjustable hydraulic pressure (20 MPa); after immersion, the tension‐tension fatigue performance was measured at stress levels of 41.7%, 33.4%, and 25.0%. Significant postcuring of resin was observed, resulting in the increase in Tgs for the core and shell layers. There was no significant decrease in the tensile strength of the hybrid rod. The fatigue failure of the hybrid rod was accompanied by debonding of CFC/GFS interface, redistribution of cyclic load, and catastrophic splitting or bursting of GFS. The immersion in water under hydraulic pressure led to a significant increase in fatigue life. The increase in the fatigue life was because of the improvement in interface bonding strength and toughness of the resin owing to the postcuring of the resin. After fatigue, significant degradation in the residual interface bonding strength was observed for the hybrid rods.

“…Thus the bottom sensor sits at Position ¼ 0, while the top sensor is at Position ¼ 100 mm. High-energy signals reportedly represent fiber breakage, while low-energy signals indicate matrix and interface failure [13,30,31]. There is no distinct boundary between the energy ranges of each damage type, and they overlap appreciably.…”

In order to simulate the vibrating condition of composite insulators in breeze, and carry out its fatigue test under loading and vibrating conditions, the electro-hydraulic loading and testing technology for the composite insulators is researched in this study. A compound electro-hydraulic loading system is first designed, including two subsystems, the static proportional loading system and the dynamic servo loading system. Then, the working principle based on this system is analyzed, and the mathematic model of electro-hydraulic servo system is also built, proved to be an inertial element with high gain. The control method based on proportional-derivative-type iterative learning control has been applied to such a dynamic servo loading system, to achieve the high-precision control for dynamic load force with repetitive regularity. Both mathematic simulation and actual experiments have been designed and carried out, and their results proved that the load principle and the control method are feasible and applicable and have the ability of achieving high-precision control effects. Based on this discussed electro-hydraulic technology, an actual electro-hydraulic loading and testing system for different kinds of composite insulators has been researched and developed, with the advanced technology indices of six loading channels, 20 kN maximum dynamic force, 0.3 kN force control precision and 100 Hz maximum vibrating frequency.
