Abstract
The issues of fabrication, evaluation and experimental testing of smart composites are discussed. The technology for the fabrication of fiber reinforced polymer composites with embedded fiber optic sensors is developed. Smart composites are produced by a custom built pultruder. It is shown that the mechanical properties of pultruded carbon reinforced composites with and without optical fiber are superior to that of pultruded glass analogue. The embedded optical fibers do not have significant effect on the tensile properties of pultruded FRP, but they deteriorate the shear strength of composites. Polyimide coating on optical fiber results in a good interface between optical fiber and host material; whereas acrylate coating cannot withstand the high production temperature and causes sever debonding of optical fiber and resin. The specific application in view is the use of smart reinforcements for innovative concrete structures.
