Production of prepregs based on nanomodified carbon and mineral fibers and nanomodified binding materials

Prepregs are semi-finished composite material produced by saturating a reinforced fibrous base with a uniformly distributed binder. Impregnation is carried out to maintain maximally the physical and mechanical properties of the reinforcing material. Prepreg technology makes it possible to obtain monolithic articles of complex forms with minimal tooling. In civil aircraft, these materials are used to manufacture airplane and helicopter bodies, wings, fairings, propellers, and rotors. Composite materials reduce aircraft weight and, consequently, fuel consumption; they also increase the strength and service life of the carriers.

Use of prepregs in production of blades for wind turbines is a promising market for expansion. In addition, prepregs can be used in the shipbuilding and automobile industries, for making ship hulls and non-weight-bearing auto body parts. In construction, prepregs can be used to reinforce concrete structures. They are adaptable to manufacturing prostheses, medical devices, and sports equipment.

Portfolio company Prepreg-SKM is building competitive domestic production of nanofilled and nanomodified prepregs from carbon fibers for polymer composite materials and finished goods. This will improve the competitiveness of Russian composite materials and significantly increase their use in Russia’s industrial sectors.

Areas of application

  • Aviation and space
  • Automobile manufacturing and ship building
  • Construction
  • Oil and gas production
  • Pipeline transport
  • Medicine
  • Wind power

Market

  • Companies engaged in producing airplanes and space vehicles, builders of automobiles and ships, producers of equipment for oil and gas extraction, manufacturers of prosthetics and sporting goods

Competitive advantages

  • Durability and fatigue resistance
  • Resistance to corrosion and chemicals
  • Elasticity
  • Light weight

Prepregs are produced by impregnating a reinforced fibrous base with a premeasured and uniformly distributed binder. The surface of the reinforcing material (carbon or glass-fiber) is nanomodified by electrochemical or plasma etching or nanoparticle coating. Polymer epoxy binders are nanomodified with polyimide oligomers.
