Composite turbomachine blade comprising a monolithic blade root

Abstract

The present invention relates to a blade (7) of a turbomachine (1), comprising a three-dimensional fibrous reinforcement (20) densified by a material, the fibrous reinforcement (20) comprising a first skin (21) and a second skin (21) facing each other, the first skin (21) and the second skin (21) each having an internal face (22) delimiting between them an internal housing (23), the blade (7) extending between a root (8) and a blade tip (14), the internal housing (23) comprising a lower limit (26) adjacent to the root (8) of the blade (7) and an upper limit (25) adjacent to the blade tip (14), the first skin (21) and the second skin (21) being monolithic at the lower limit (26), the blade (7) thus comprising a homogeneous zone (29) of fibrous reinforcement (20) between the lower limit (26) and the root (8) of dawn (7).
