Multifunctional composites include all composites which provide more than one property, or functionality, whether specifically designed or modified from existing designs. Although traditional polymer matrix composites have many useful properties including stiffness, strength, and durability, these often involve tradeoffs such as poor acoustic damping and low electrical conductivity. By designing multifunctional composites, new and enhanced functionalities can complement the typical high-stiffness and high-strength densities of composites. Furthermore, multifunctional composites can feature...
