Hybrid materials combine the properties of two (or more) monolithic materials or of one material and space. They include fibrous and particulate composites, foams and lattices, sandwiches, and almost all natural materials Materials Selection in Mechanical Design, 4th Edition © 2010 Michael Ashby Figure 11.1

All material property charts examined thus far have been populated with holes. One approach to filling these holes is by developing hybrid materials that have the desired property profile Materials Selection in Mechanical Design, 4th Edition © 2010 Michael Ashby Figure 11.3 Figure 11.3 shows holes in modulus-density space. Material development that extended the occupied territory in the direction of the arrow allows components with greater stiffness to weight than any current material allows
