4 Claims

1. A process for manufacturing a composite material component comprising a fiber reinforcement based on carbon fibers densified by a matrix, the process comprising successively producing a fiber structure by multilayer three-dimensional weaving, placing the fiber structure in a closed mold, and injecting a resin into the mold, wherein during weaving of the fiber structure, the process further comprises spraying carbon nanoparticles onto the carbon fibers, the weaving of the fiber structure being performed using a loom, and the spraying of carbon nanoparticles onto the carbon fibers being performed at a shed opening created by lifting certain carbon threads from others, wherein the spraying is carried out using a comb or a spraying device mounted on the comb of the loom.
