    摘要: A method of locally treating a portion of a part made of composite material including fiber reinforcement densified by a matrix, the material presenting internal pores, the method including: determining a quantity of infiltration composition as a function of a volume of the portion of the part to be treated, the infiltration composition including at least silicon; placing the determined quantity of infiltration composition in contact with pores opening out in a surface of the portion of the part to be treated; and applying heat treatment at a temperature higher than or equal to a melting temperature of the infiltration composition so as to impregnate the portion with the treatment composition and fill in the pores present in the portion.
