In Smart Structures, other functionalities than only structural performance are integrated in the product. Especially composites lend themselves well for this novel approach, because they are multi-layer materials already. Within the Airborne Technology Centre, we work on the following topics.

• Sensing materials, by integrating optical fibre sensors in the composite. With these sensors, the deformations, loads, temperature or chemical status can be monitored. The optical fibre technology uses the influences of these parameters on the reflected light for measurement of the properties. The optical fibres are well suited for integration in the composite. Points of research are the influence of the different optical fibre on the mechanical behaviour of the composite, the connectorisation of the integrated optical fibre to the measurement system, and cost efficient technologies for integrating the optical fibres in the composite.
• Active materials, such as piezo-ceramic materials or shape memory alloy wires. These materials can be actively deformed, which turns the structure into an actuator. Applications are in vibration control, high-precision deformations or shape morphing.
• Nano-composites. The properties of the composite can be changed by adding nano particles such as carbon nanotubes or nano clay to the resin. Mechanical properties such as interlaminar strength, through-thickness properties or stiffness at elevated temperatures can be improved. Also thermal and electrical conductivity can be largely improved.
• Self-healing. New technologies are being developed to give composites a self-healing capability in case of damages such as delaminations or cracks.
