Abstract

Quasi-static testing of the fabric material mechanically with a novel embedded strain measurement system, which aimed at mechanical analysis of the dynamic characteristics of the parachute canopy textile with fiber optic technology, and using a tensile tester were aimed at correlating the results obtained by using the fiber optic sensors to the mechanical parameters, and in calibrating the system. To achieve better and more consistent results, FBG sensor took part in fabric samples testing in the warp, fill, and 45° directions. The mechanical tensile tests provided a traditional correlation between the loads and the elongation of the fabric structure, and were correlated to the fiber optic sensor output calibration. The comparison shows clearly that the two curves converged in the loading region before the structural failure started. The achieved results were consistent with each other, which dues primarily to the consistency in the fiber embedded technique, and will be discussed in detail in this paper.
