Abstract
In the last decade, the focus of application for advanced composite materials has slowly turned from aerospace to marine, civil, construction, and transportation industries. The properties of composite materials which make them attractive for such applications include their high strength to weigh ratio and resistance to corrosion. Composites have recently been used in civil engineering applications including rehabilitation projectors, prestressing tendons, reinforcing bars, and most recently as innovative structural members of bridges. As well, they have found many applications in the quest to reduce the top side weight of marine vessels. Composite sandwich panel hulls are also becoming more common. The use of composite materials on such applications has been slowed somewhat due to the fact that they are the "new kid on the block", and because there is a lack of reliable long term field data, as compared to the traditional structural materials such as steel. Designers also need larger and more standardized databases of material properties for the multitude of existing composite materials. For these reasons, composite materials lend themselves as prime candidates for another rapidly expanding field of research known as "smart materials". A smart material is a structure which contains a built in sensing device that can be used to continuously monitor the current state and serviceability of the structure. TRUNCATED
