| Description | A smart manufacturing is one of the most important technologies in the field of smart composites. Fiber optic sensors are suitable to smart composites as sensors and used to measure internal strain or temperature. Then, sensor technologies using optical fiber sensors have been studied for measurement of internal strain, temperature and detection of damages in composite laminates. However, there are few applications for FW (Filament Winding) molded composites which are used in many fields of advanced and consumer engineering. To develop high-functional FW molded composites for improvement of the reliability and total cost including maintenance cost, it is important to study the smart manufacturing technique. In this paper, internal strain measurements of FW GF/Ripoxy and GF/Epoxy pipes with EFPI (Extrinsic Fabry-Perot Interferometer) optical fiber sensors were conducted in the curing process. A FW molding machine was remade to easily embed optical fiber sensors in a midplane of the thickness. From the experimental results of GF/Ripoxy pipe in the room temperature (RT) cure, it is found that the end of cure can be detected. At the curing stage of GF/Epoxy pipe, curing shrink was detected. Internal strain outputs of GF/ Ripoxy pipe in the after-curing process shows large residual strain at the cooling stage due to the resin rich around an embedded optical fiber sensor. Internal strain in GF/Epoxy pipe represented thermal shrink very well. It is found that the internal strain of FW pipe can be measured with optical fiber sensor. Then, It is concluded that optical fiber sensors are useful for smart manufacturing of FW molded composites, but more detail researches are necessary for quantitative cure monitoring.
