Résumé

The work focuses on the mechanical strength of composite structures with embedded electrical functionalities submitted to low energy impact. This material is defined for aeronautical applications as multilayers of Glass fibre composite with flat electrical cables layers embedded. The main question is about the damage involved by the low energy impact, and its influence on the electrical cables layer. The impact leads to failure with no external signs of damage and insulation degradation. Experimental campaigns are carried out on drop tower test in dynamic bending and hemispherical punctual impact on clamped specimens at low energy (between 10 and 25 Joules). Finite element models with composite progressive damage laws coupled with failure criterion give a prediction of the different mechanisms.
