3D-Printed Polymer Lattice Strengthens Concrete

摘要

Brian Salazar and his UC Berkeley team have developed a new way to reinforce concrete with a polymer lattice, an advance that could rival other polymer-based enhancements and improve concrete's ductility while reducing the material's carbon emissions.Tech Briefs: How did this project start?Brian Salazar: The lattice we used is called the octet structure - Buckminster Fuller used it for his kites and it's been used for many other structures. Before we worked on this, our team was working on a project using cellular cementitious materials. We were directly shaping concrete into a lattice structure and found that provided good performance. But concrete is a very brittle material that always has to be reinforced.
