Research on Magneto-Rheological Fluids Torsional Damper and Control System Applied to Controlling Carbon Fiber Strain

Abstract:

One fiber stain measure and control system has been designed to meet the problem that the magnitude and uniformity of the fiber strain directly determine the properties and longevity of the carbon fiber continuous sucker rod during the pultrusion process. In this system, there are 2 key technologies. The first one is the sensor that is used to measure the micro bend strain of the carbon fiber during the pultrusion process, designed base on fiber micro-bend principle, using silicon film as sensitive element and fabricated by silicon integrated circuit technology and three dimensional processes. Another is the executive unit of the system: Magneto-rheological Fluids torsional damper, which is designed base on one type of intelligent material named Magneto Rheological Fluids which can change its viscosity in millisecond according to the magnetic strength around it. So this paper provides a technical means to ensure the quality of the pultrusion process applied in fabricating the carbon fiber continuous sucker rod.
