Abstract Scope |
Syntactic foams are a class of composite materials created by binding hollow spherical particles within a matrix and are primarily characterized by their high strength-to-density ratio. Properties of the foams can be tailored through factors such as relative loading of microspheres and the degree of heat treatment during post-processing. These characteristics have motivated widespread use of syntactic foams in lightweight industrial applications. At the same time, additive manufacturing has emerged as an efficient method to create components with custom or complex structures. However, application of syntactic foams as feedstocks for additive manufacturing is limited by the constituent microspheres’ tendency to cause jamming when present in significant amounts. In this work, we characterize a new technique for creating low-density, high temperature syntactic foam structures via material extrusion additive manufacturing comprised of epoxy resin, glass microballoons, and solvent blend that acts as a fugitive carrier for the composite constituents. |
