Sponsored news - Development and innovation create the main preconditions for increasing the competitiveness of the national economy. Russia focuses on modernization and innovation policy as its key economic development. This policy requires applications of the most advanced materials and enabling technologies in basic industry, construction and transport.

The Ruscompozit Group is one of the leaders of the Russian composite materials industry, who is engaged in activities pivotal in the development and implementation of the most modern and innovative solutions in various areas.

The company boasts two production sites - the Steklonit factory of Ufa and the Tverstekloplastik factory of Tver, which originated from the post-war industrialization of the Soviet Union. Productions were commissioned in 1958 (the Steklonit factory) and 1959 (the Tverstekloplastik factory). After the onset of the economic reforms the factories were reincorporated as joint - stock companies and taken over by private Russian investors. At present the Ruscompozit Group employs more than 1,500 people and annual revenues account for over EUR 70 million.

The Ruscompozit Group key products are supplied for the construction of transport infrastructure and facilities of oil and gas production and transportation. The Ruscompozit Group aims at developing and delivering complete integrated composite-based solutions. For instance, to construct and repair highways, the Company provides, conduit pipes, containers to drain storm and melt, railings for footways, pedestrian overpasses, and other products. The Company is planning to produce composite noise screens, cars guardrails, and light masts.


Heavy machine works on swamps with use MRP-MOBISTEK

The company has set up a highly effective Research & Development Department for development, manufacturing applications and supplies of integrated solutions of polymer composites for various purposes. This department comprises a numerical simulation unit, design, technology and test sections, a material properties research laboratory and a prototype production facility. Thanks to streamlined research work, introducing new products into production takes minimum time. For instance, it took less than 2 years to develop a new design of an all-composite superstructure of the pedestrian overpass, provide its analysis, test more than 2,000 specimens of materials and fragments of the structure, complete the technology, and obtain permits and approvals.

The unique development of the Ruscompozit Group is the MRP-MOBISTEK Mobile Road Pavements. The MRP-MOBISTEK is a pavement allowing performance of construction and installation works as well as delivery of automotive and track vehicles weighing up to 80 tons under conditions of swamps and weak grounds featuring a Young’s modulus of about 0.25 MPa. The plates feature positive buoyancy and may be easily extracted even out of swamps upon completion of works. Practical experience showed that these characteristics are missing in similar products from other manufacturers.

Compared with typical traditional solutions MRP-MOBISTEK has a number of significant advantages, including the rapid deployment of the system (1 km/48 h) and the possibility of using transport helicopters in difficult-to-reach area.

M1 "Belarus" Highway Bridge

In 2013, for the first time in Russia the Ruscompozit produced and supplied for the construction of pedestrian bridges monolithic all-composite superstructures made by vacuum infusion. This product is unique because in the Russian context it must not only withstand a given mechanical stress, but also temperature drop between -50 and +50°C. Furthermore, the structure must be fireproof and resistant to attacks due to de-icing agents.

The pedestrian bridge design developed by the Ruscompozit Group features an enhanced reliability due to solid-cast structure. The span has no screwed joints, nor fiber exposure to product surface, which ensures a longer service life of 70 years at least, according to the Company's specialists.

By 2013 the Ruscompozit Group has constructed two pedestrian bridge overpasses using superstructures of its own making: a bridge over a river that connected two neighborhood estates in Starobaltachevo village (Republic of Bashkortostan) featuring a length of 20 m and a width of 2.25 m, and an overpass of a total length of 42 m and a width of 3 mover the М1 Belarus highway.

The superstructure's solid-cast design features a high rigidity, which enhances comfort for pedestrians: bending due to pedestrian load does not exceed 1/700 of the span length with minimum natural oscillation frequencies equaling to 5 Hz, at most.

The facilities' light weight allowed simplifying the pillars design and reducing considerably the superstructures' installation time–installation of the pedestrian overpass over the М1 Belarus highway took nothing but 30minutes.
