Abstract

Compared to conventional metal piping, fiber-reinforced polymer composite (FRPC) pipe has several attractive characteristics, among them high corrosion resistance and strength-to-weight ratio. In addition, manufacturing processes commonly employed for FRPC piping, such as filament winding, facilitate the incorporation of liner systems that are intrinsically bonded to the structural pipe body, and structural health monitoring systems. The present study investigates how metallic filaments embedded in the liner structure or the structural pipe body can be employed for structural health monitoring purposes. Using electrical induction effects a direct contact to embedded metallic filaments may not be required; information on the structural health state of liner and pipe may be obtained using excitation and sensing coils located on the outside of the pipe. In this study the feasibility of such a system was demonstrated using filament-wound FRPC tubes with embedded strain-sensitive metallic filaments.
