Published: March 12, 2025

Abstract Carbon fiber‐reinforced polymer composites are susceptible to damage in practical applications, and their repair has attracted significant attention. In this study, an electric heating (EHR) method was proposed for repairing fatigue of short carbon (SCFRPCs), leveraging the intrinsic electrothermal effect SCFRPCs. First, EHR evaluated through mechanical testing, both tensile strength fracture toughness SCFRPCs were improved after EHR. The temperature specimens reached approximately 115°C (close matrix's melting point ~120°C), demonstrating efficacy method. Subsequently, influence power duration on effectiveness systematically analyzed. With optimal parameters, maximum improvements strength, toughness, ductility 19.3%, 74.0%, 13.8%, respectively. Conversely, insufficient or excessive parameters diminished effectiveness. Furthermore, microstructures original, fatigue‐loaded, repaired quantitatively compared, including fiber‐matrix interfaces fiber failure modes. Quantitative analysis indicated interfacial bonding between fibers matrix EHR, transitioned from pull‐out breakage This enhanced at microscopic accounts restored macroscopic properties. Overall, demonstrated its capability damages SCFRPCs, offering a promising situ approach composite structures. Highlights Electrical effectively repairs composites. Optimal significantly enhance Enhanced observed electrical repair. Tensile quantified. Intrinsic effect‐based is

This work aims at the effects of anion-exchange membranes (AEMs) and ionomer binders on catalyst electrodes for membrane fuel cells (AEMFCs). In experiments, four metal catalysts (nano-grade Pt, PtRu, PdNi Ag), AEMs (aQAPS-S8, AT-1, X37-50T X37-50RT) two alkaline ionomers (aQAPS-S14 XB-7) were used. They verified through several technical parameters examination cell performance comparison optimal selection AMEs. The bimetallic nanoparticles (PdNi/C) loaded with Vulcan XC-72R carbon black used as anode by using wet impregnation method, Ag (Ag/C) cathode. It was found that power density current X37-50RT are higher than other three membranes. Also, XB-7 had better aQAPS-S14. efficiency improved 32%, 155% 27%, respectively, when compared to same PdNi/C, Ag/C Pt/C. results consistent ion conductivity measurements, which showed is highest among them. values hydroxide ions (OH
