Techniques are described for infiltrating a nanofiber yarn with an infiltration material and removing a surface layer of the infiltration material on at least a portion of the infiltrated nanofiber yarn. This enables an infiltration method by which the infiltration material is selectively disposed within an interior of a nanofiber yarn and not disposed on an exterior surface of at least a portion of a nanofiber yarn. Electrical connection can be established by mechanically connecting an electrode (e.g., a conductive clamp or fitting) directly to the exposed surface of the nanofiber yarn.

The invention relates to a method for making a composite part including an assembly of superimposed webs of reinforcement threads imbedded at least partially in a polymer matrix, said part including at least one curved area and the method comprising steps of draping or stacking plies of a composite material, characterized in that, in at least one area adjacent to a curved area, at least one draping or stacking step is carried out with a ply of composite material, that comprises a web, or twisted thread web, including at least one twisted reinforcement thread in order to at least compensate the length differences of the extreme paths of the thread on either side of the width as measured in a direction parallel to the surface of the web; the invention also relates to the composite materials thus obtained.

The invention relates to a composite material in which at least one reinforcement thread is deposited on a surface according to a path having at least one curved area on the deposition surface, wherein the reinforcement thread is connected to the surface by a polymeric binder. A twist is applied to the reinforcement thread before the deposition thereof at least in order to compensate the length differences of the extreme paths of the thread on either side of the width as measured in a direction parallel to the deposition surface.
