摘要：

The electromagnetic interference shielding effectiveness and return loss of short carbon fiber filled polychloroprene rubber composites of varying sample thickness and fiber aspect ratio were studied in the frequency range of 8 to 12 GHz (X-band). It was observed that composites prepared by "cement mixed" method having high fiber aspect ratio (L/D = 100) show higher shielding effectiveness and lower return loss than the composites prepared by "mill mixed" method with low fiber aspect ratio (L/D = 25). This indicates that loss due to absorption increases with increasing fiber aspect ratio. Similar effect has also been observed with increasing sample thickness.
