Paper Abstract

In this article, a new method is put forward to research mechanical features of braided material using co-braided optic fiber sensor. Optic fiber sensors can be multi-braided into composites to measure various internal parameters, which overcomes the drawback of ordinary mechanical experimental methods and makes measurement more accurate and reliable. Followings are introduced in detail: the devising of carbon fiber braided composite specimens with co-braided optic, the AEFPI optic sensor adopted and the experiments to measure the tensile strain and thermal strain of specimens. It is the first time to use co-braided AEFPI sensor to research the mechanical features of brading composites and experiment results are satisfying.
