Fabrication and testing of smart FRP reinforcements

摘要

The aspects of fabrication, microstructural evaluation and experimental testing of smart composites are discussed. The technology for the fabrication of fiber reinforced polymer composites with embedded optical fibers is developed. Smartcomposites are produced by a custom built pultruder. The pultruded carbon reinforced rods with and without optical fiber showed higher shear and tensile strength, as well as greater tensile modulus than did the glass fiber analogue. The embedded opticalfibers do not have significant effect on the tensile properties of pultruded rods, but they slightly affected the shear strength of the glass fiber rods. Poly-imide coating on optical fiber results in a good interface between optical fiber and hostmaterial; whereas acrylate coating cannot withstand the high production temperature and causes severe debonding of optical fiber and resin.
