TL;DR
This paper introduces a new optimization method for self-healing composites with microtubule networks to improve their mechanical and self-healing properties.
Contribution
A dual-scale collaborative optimization framework combining variable-angle fiber design and microtubule network carrier optimization is proposed.
Findings
Variable-angle fiber design outperforms fixed-angle designs in terms of non-inferior solutions.
Dual-scale optimization reduces compliance by up to 10.64% compared to single-objective optimization.
The framework provides a better balance between structural compliance and carrier head loss.
Abstract
To enhance the mechanics and self-healing properties of the self-healing composite, this study introduces an innovative optimization method for variable-angle fiber-reinforced self-healing composites with microtubule network carriers. The study aims to minimize macroscopic structural compliance and carrier head loss. Firstly, a topological description function (TDF) for the self-healing composite was introduced, taking into account the configuration and geometry of the macroscopic structure and microtubule network carrier as design variables. Secondly, the relationship between the fiber laying angle and component spindle direction was established. An element stiffness matrix for variable-angle fibers was derived to determine the compliance of the self-healing composite. Then, the microtubule network head loss was calculated based on the Hardy Cross method. Finally, by integrating the…
