FIBRE-REINFORCED, NANOPARTICLE-FILLED HEAT-SHRINKING POLYMER-COMPOSITE WIRES AND CABLES AND METHODS Russian patent published in 2017 - IPC H01B5/08 

FIELD: chemistry.

SUBSTANCE: invention discloses heat-shrinking polymer-composite wires, which include a plurality of substantially continuous fibres embedded in a hardened polymer-composite matrix and which form a substantially continuous fibre. The hardened polymer-composite matrix further includes a polymer formed by hardening the starting polymer material from a liquid state, and a plurality of nanoparticles having mean diameter of 1 mcm or less, substantially uniformly distributed in the polymer-composite matrix, and said particles consist of silicon dioxide particles, calcite particles or combinations thereof, and optionally a corrosion-resistant cladding substantially surrounding the continuous fibre. In some versions, the plurality of particles includes surface-modified particles having a core and a surface-modifying substance bonded to the core and reacting with the polymer hardened from a liquid state. The invention also describes multi-wire cables, which include one or more said heat-shrinking polymer-composite wires, and methods of producing and using said heat-shrinking polymer-composite wires and multi-wire cables.

EFFECT: invention improves strength and mechanical properties of composite wires.
