Reversing fatigue in carbon-fiber reinforced vitrimer composites

Mithil Kamble et al.

Summary: Most current approaches to combating fatigue in carbon-fiber reinforced polymeric composites are unable to reverse the fatigue process. This study introduces a vitrimeric system that can repeatedly reverse fatigue damage by heating the material above its topology freezing transition temperature. This innovation allows for intermittent healing of fatigue-induced damage, postponing fatigue failure indefinitely.

A laminated vitrimer composite with strain sensing, delamination self-healing, deicing, and room-temperature shape restoration properties

John Konlan et al.

Summary: This study successfully developed a laminated composite material with multiple functionalities, including impact tolerance, delamination healing, strain sensing, Joule heating, deicing, and room temperature shape restoration. By using a novel self-healable and recyclable adhesive as the matrix, and twisting the SMA wires into sinusoidal shape, a multifunctional design for the composite material was achieved.

Experimental investigation of flexural properties of glass fiber-epoxy self-healable composite structures containing capsulated epoxy healing agent and NiCl2(imidazole)4 catalyst

Hossein Ebrahimnezhad-Khaljiri et al.

Summary: The study focused on fabricating glass fiber-epoxy self-healable composites with encapsulated healing agent, and investigating the effects of different ratios of encapsulated epoxy and damage forces on their healing ability. Increasing the microcapsules improved healing ability but slightly reduced flexural strength. As damage forces increased, the healing ability decreased, transitioning from matrix cracking to fiber breakage.

Room-Temperature Self-Healable and Mechanically Robust Thermoset Polymers for Healing Delamination and Recycling Carbon Fibers

Xiaming Feng et al.

Summary: The article introduces a dual-cross-linked network structure of glassy thermoset polymers. The highly mobile and dense noncovalent hydrogen bonds at the chain branches and ends achieve high mechanical robustness and healing ability, with a healing efficiency of over 84% at 20 degrees Celsius.
