A mechanical model of three-dimensional electrospun fiber scaffolds

Abstract

Abstract Fiber scaffolds prepared by electrospinning method can be used for the repairing of soft tissues such as skin, and have been widely used in biomedical field. The mechanical properties of scaffolds needed to be considered in the process of preparing scaffolds. Based on the principle of statistics and the method of micromechanics, a mechanical model for calculating the elastic characteristics of fiber scaffolds with spatial random distribution characteristics was established. The model comprehensively considered the parameters such as mechanical properties of constituent units of fiber scaffolds, fiber diameter and fiber density. The quantitative relationship between the elastic mechanical properties of fiber scaffolds and their tissue unit parameters can be calculated, which provided a research basis for further research and improvement of the mechanical properties of three-dimensional fiber scaffolds.
