| Research Abstract |
In this study, a specimen manufacture method and a compression test method to estimate axial compressive strength of very thin macromolecule-based fiber as approximately 10μm were developed. PBO fiber was used in the experiment as a representative of the high polymer fiber. Photolithography techniques have been applied in semiconductor manufacturing was used to prepare the fiber specimens. The developed method enables the preparation of compression test specimens. In the axial compression tests of single fiber it was found that the locating fracture points by in situ observation lead to improve the reliability of compressive strength.
