A method for manufacturing a structure by additive manufacturing, comprising:
- forming a reinforcement by chemical vapor deposition assisted by focused energy radiation, the reinforcement being deposited along a deposition axis and comprising a plurality of interconnected reinforcing elements made of ceramic or carbon, said interconnected reinforcing elements being formed by chemical vapor deposition assisted by focused energy radiation from at least one gaseous precursor, and the interconnected reinforcing elements as formed by the chemical vapor deposition assisted by focused energy radiation from at least one gaseous precursor defining therebetween an interstitial volume having a tortuous shape along said deposition axis, said interstitial volume having a sinuous and non-rectilinear shape when moving along said deposition axis.
