| Abstract: | A technique of preparing TEM Samples of Carbon fibres and C-C Composites has been investigated. Microtomy have many advantages. A Comparision has been made with ion bombardment. Microtomy with a diamond Knife permits to prepare thin foils Samples with high transparency of electron, good parallelism and have a clean Surface. analysis has been done to identify the Artefacts introduced during the preparation of thin foils in TEM observations. |
