To make shipbuilding fasteners, scientists from the Institute of High Molecular Compounds of the Russian Academy of Sciences (IMC RAS) have developed a new composite material from basalt fiber-reinforced polymers.

The requester is the Sredne-Nevsky Shipyard that issued technical requirements for BFRP fasteners development.

The fasteners in the shipbuilding industry should meet high standards. These components are subject to heavy loads in an aggressive marine environment. Most often, fasteners are made of special grade steel.

We offer to replace metal fasteners used in shipbuilding with fasteners made of lightweight composite materials. We have developed a polymer composition filled with basalt fibers. A fastener made of this material is five times as light as metal and far cheaper,

says Sergey Lyulin, the director of IMC RAS.

The Institute produced pilot samples, claiming that the novel composite material is not inferior to those made of metals in mechanical properties. Furthermore, BFRP composite resists to corrosion in harsh marine environment.

To provide further development and testing of composite products at IMC RAS, the Center for Materials Chemistry for Shipbuilding was established. They plan to implement new products at the facilities of the United Shipbuilding Corporation (USC).

The materials for the shipbuilding the corporation intends to apply include non-combustible materials, hybrid and polymer protective coatings.

Meanwhile, in Europe, the FIBRESHIP project is being developed. It focuses on total replacement of metal parts in ships with fiber-reinforced polymer materials. Recently, they have showcased a section of the hull built using fiber-reinforced polymer.
