Abstract: This application relates to a method for analyzing the dynamic characteristics of carbon composite materials. In the method, a specimen for a specific carbon fiber orientation is prepared and a modal test is performed on the specimen to obtain data and analyze the characteristics of the specimen on the basis of the data. To solve conventional carbon composite material dynamic characteristic analysis methods for carbon composite materials, the proposed method can determine the orientation of carbon fiber orientation exhibiting desired dynamic characteristics by predicting various system parameters at the state of designing, i.e., before the manufacture of a carbon composite material. Especially, the method predicts system parameters such as structural stiffness and viscous damping coefficient which are very sensitive to the orientation of carbon fiber, using only data of a single reference orientation, and reflects the prediction results on the design of a carbon composite material.

Abstract: An apparatus and a method for rapid monitoring of inkjet ink droplets using time delay integration are proposed. Inkjet ink droplets used in manufacturing a display panel may be captured for a set period of time using a wide one-dimensional (1D) line scan camera to obtain a plurality of pieces of high-resolution small-amount image data. The obtained plurality of pieces of high-resolution small-amount image data may be subjected to image processing to generate ink droplet two-dimensional (2D) time-space information. The ink droplet two-dimensional (2D) time-space information may be compared with pre-stored reference ink droplet 2D time-space information to determine whether the ink droplets are normal.
