Construction of Three-dimensional Co-continuous Composites with Controllable Volume Fraction

Abstract

Abstract Efficient and low-cost manufacturing methods and adjustable properties are an important way to further promote the application of co-continuous composites. In this paper, a three-dimensional co-continuous composites model with controllable volume fraction is designed. The model uses triply periodic minimal surface (TPMS) as the internal structure and spatial segmentation strategy to accurately control the volume proportion of each phase, which enriches the three-dimensional modeling method of co-continuous composites and provides new ideas and methods for the wide application of co-continuous composites with adjustable characteristics. Finally, samples are manufactured through efficient and low-cost 3D printing technology.
