• Composite materials are currently developed not only for their structural properties, but also because they are good candidates to integrate other materials or devices, which bring added functions to the part. Several examples are presented based on recent work performed at LTC, which cover the areas of damping and self-repair. Tailored damping has been addressed following two different routes: (i) active damping using Shape Memory Alloys (SMA) is made possible by embedding pre-strained SMA wires into a host material ; (ii) another route to damp some unwanted frequencies in a composite beam is to introduce a layer with shear thickening properties, which stiffens when the local shear exceeds a given level, without the need for an external energy source. Finally, recent research on self-repair of composites using embedded resin micro-capsules and SMA wires for closing cracks and heating the resin will be presented. In all these examples, manufacturing issues are addressed to bring these concepts closer to practical applications.
