Abstract
A composite yarn comprising a continuous multifilament core yarn incorporated in a matrix, is characterized in that the matrix comprises at least one polymer material and at least one reinforcing filler, the reinforcing filler being formed from functionalized particles, said particles having a median size (dv50) of less than 40 μm. A process for manufacturing such a composite yarn, comprises at least one step of depositing, by coating or extrusion, a matrix comprising a polymer and a reinforcing filler, onto a core yarn. A textile surface comprises at least one such composite yarn.
