Abstract
The method for warning of risk of rupture or deformation of a part made of a composite material when it is subjected to a force relates to a part including a fibre-reinforced thermoplastic or thermohardenable matrix. The method includes arranging the fibers in a lattice structure produced by winding fibers to form bars that join together or intersect at nodes. The method includes designing at least one bar of the lattice and/or integrating, into the part, at least one additional bar with a determined location and tensile strength and associating, with the at least one bar, inside the part, a sensor to detect the rupture thereof. The method further includes associating, with the sensor, an emitter, outside the part, for a signal relating to the rupture.
