Furthermore, the compression-sensitivity of CFRC, which suffers three-direction-pressure is studied.Thirdly, present method of carbon fiber treatment is summarized. Treat the surface of carbon fiber with GLBE, the influence of surface-treatment of carbon fiber on the distribution and compression-sensitivity of CFRC was studied. According to the contrast of the compression-sensitivity before and after surface treatment, as well as the contrast of the distribution of carbon fiber in cement mortar, it is found that GLBE is able to improve the dispersiveness of carbon fiber.

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.
