【 摘 要 】

Poor quality of the carbon preform including missing rods can affect the desired properties of the tailored composite. The carbon preform is currently manufactured manually and therefore, an effective solution for guaranteeing the quality of carbon preform is needed. This paper proposes new inspection method that can detect the missing rods of carbon preform by just taking a picture of it. The new method found all missing rods and marked missing place with red circle. By wide use of smart devices, it becomes very easy to take a picture nowadays and the picture quality has improved dramatically. Moreover, the inspection method suggested in this paper can be easily converted into a form of android application and it is expected to be applied effectively to the fields of manufacture of the carbon preform.
