Recently, the research team of Wei Yujie, a researcher at the State Key Laboratory of Nonlinear Mechanics, Institute of Mechanics, Chinese Academy of Sciences, reported on stacked amorphous carbon-based composites with high strength and high toughness through atomic-scale simulations and theoretical analysis, and revealed the effects of nano-scale folds.

Low-dimensional carbon-based materials such as graphene have extremely high in-plane strength and Young's modulus, but their three-dimensional stacked structure is difficult to inherit these advantages and exhibits extreme brittleness.

Xie Wenhui, a doctoral student in the Institute of Mechanics, is the first author of the paper, and Wei Yujie is the corresponding author of the paper.

A three-dimensional stack of two-dimensional amorphous carbon, the resulting amorphous carbon-based composite material has high strength (~3.
