Outline of Final Research Achievements |
By means of digital image correlation (DIC) method, time dependence of mechanical property of triaxial woven CFRP is investigated. The triaxl woven CFRP is intended for using in space and it is flexible and behaves as membrane. Although it is conventionally difficult to evaluate the mechanical property because its structure is complecated, employing DIC unable us to do it. One of the remarkable findings obtained in this study is that macro creep strain increases with time under a creep loading condition but fiber directional strain does not. This is due to "scissoring effect" involving woven stractural change. Now we can discuss a long-term durability of the triaxial woven CFRP.
