on the surface free energy of the carbon fiber after sizing by the electropolymerization. Compared with the unsized carbon fiber, which has 85.6°of contact angle of water,52.2° of contact angle of diiodomethane.... The sized carbon fiber was washed by distilled water and dried in a vacuum. 2.2 Contact angle measurement Contact angle was used as a parameter to characterize the wetting performance and surface free......

Deformed texture of copper processed by equal channel angular pressing via different angle routes WU Bao-lin(武保林)1, HUANG Zhen-wei(黄震威)1, ZHANG Yu-dong(张宇东)1, 2, BAO Lei(宝 磊)1 , C. ESLING2 1... is corresponded with that of rolling deformation modes. Cold-deformed texture was investigated. The results show that the texture character in pure copper processed by ECAP is related with intersection angle (F......

and optical fiber arrays based on machine vision. The experimental results show angle detection precision levels higher than 0.05°, line detection precision levels higher than 0.1 μm, and detection time less than 2 s. Therefore, the system developed herein meets the precise requirements necessary for position detection, and angle and spacing adjustments for optical waveguide chips and optical fiber......
