Design framework for mechanically tunable soft biomaterial composites enhanced by modified horseshoe lattice structures

Abstract Soft biomaterials have a wide range of applications in many areas. However, one material can only cover a specific range of mechanical performance such as the elastic modulus and stretchability. In order to improve the mechanical performance of soft biomaterials, lattice structures are embedded to reinforce the biomaterials. In this paper, rectangular and triangular [...]
