1. A method for treating a surface of an aircraft part made of organic matrix composites and for assembling said aircraft part, the method comprising:
a texturing step in which the surface is irradiated by femtosecond laser pulses so as to make the surface superhydrophobic; and
assembling a piezoelectric component with said aircraft part, the piezoelectric component forming a mechanical de-icing device being configured to generate vibration to break ice accumulated on the surface of the aircraft part.
