A process for manufacturing a monofilament made of glass-resin composite comprising glass filaments embedded in a resin comprises: creating a rectilinear arrangement of glass filaments and conveying this arrangement in a feed direction: in a vacuum chamber, degassing the arrangement of glass filaments by the action of the vacuum; at the outlet of the vacuum chamber, after degassing, passing through an impregnation chamber under vacuum so as to impregnate said arrangement of glass filaments with a photocurable resin composition in the liquid state to obtain a pre-preg containing the glass filaments and the resin composition; passing said pre-preg through a sizing die having a cross section of predefined area and shape to provide it with the shape of a monofilament; and downstream of the die, in a UV irradiation chamber, polymerizing the resin composition under the action of the UV rays.
