摘要

Fold of fibers having a protective film comprising detectable particles embedded in a material matrix and method of manufacturing a composite material part comprising at least one step of detecting pieces of protective film The invention relates to a ply of fibers comprising at least one layer of fibers (10) as well as at least one protective film (18) comprising particles (24) embedded in the mass, exhibiting at least one different physical characteristic. those of the fibers of the layer of fibers (10) in order to make them detectable by at least one suitable sensor (26), the particles (24) being distributed homogeneously over the entire surface of the protective film (18). The subject of the invention is also a method of manufacturing a part made of composite material comprising at least one step of detecting any protective films or pieces of protective films by virtue of the particles present in the protective film before a step of polymerization.
