Abstract
The invention relates to a part made of composite material comprising - chips (1), each chip (1) having a substantially constant thickness defined between two parallel opposite faces (4) of the chip, each chip comprising carbon fibers (3) at least partly included in an adhesive cured during a first curing prior to the formation of said part, at least a majority of said fibers of the chip extending substantially parallel to said opposite faces (4) of the chip and - a matrix (2) in which each chip (1) is at least partly included, said matrix (2) being formed of an adhesive cured during a second curing, so that a bonding interface is formed between the matrix (2) and each chip of the part.
