Static and dynamic characterization of a woven eco-composite young’s modulus and acoustic emission analysis

The study describes the mechanical characteristics of polymer matrix composite reinforced with vegetable jute fibers such as Young's modulus variation according the orientation of the fiber. The jute manufacture fiber in warp and weft direction was associated by impregnation with a green liquid thermoplastic resin. Samples of stack laminated composite have been tested in static and dynamic analysis according the fiber orientations using acoustic emission monitoring. The obtained results for the dynamic tests have highlighted their approaches in relation to the static test. The acoustic emission data were processed using a global approach, in order to associate the acoustic signatures of the damage mechanisms during the test, and to understand their influence on the mechanical behavior of the material.
