DEVELOPMENT OF EPOXY RESIN CARBON BLACK SMART COATING MATERIAL FOR STRUCTURAL HEALTH MONITORING OF PETROLEUM PIPELINES
The service life of a structure can be extended by periodic monitoring of its integrity; every structure subjected to excitation will vibrate at its natural frequency, a deviation from this value is an indication of damage. Structural health monitoring offers the prospective for regular and periodic appraisal of the safety and reliability of structures. This study presents the use of epoxy resin / carbon black nanocomposite as a smart coating for the capturing of vibration data of an excited petroleum pipeline. The laboratory rig used was modeled using parameters from an existing petroleum Pipeline. The damage indices obtained in the research reveal a damage of 10.22 % defect on the damaged pipeline. Data obtained using the nanocomposites were successively decomposed using the Hilbert Huang transform, the integrity of the proposed method was checked by data captured using an accelerometer. The damage index obtained from the vibration data captured by the accelerometer is rather too high (14.53 %); this could be attributed to the sensor location and may require additional number of accelerometers to capture the vibration data that will generate accurate damage index of the entire pipeline. The study recommends the calibration of the data obtained with the view to optimized the use of the nanocomposite for structural health monitoring.
