Significance for science
The project contributes to the treasury of knowledge in two different areas, i.e., in the area of the mechanics of time-dependent materials and in the area of environmental protection against noise pollution and vibrations.
From the point of view of time-dependent materials the results of the project contribute to understanding of vibration (damping) properties of elastomeric materials that are loaded periodically and/or exposed to the impact dynamic loading. We were mostly interested in how dynamic loading influenced on the structure and consequently on the behaviour of elastomeric materials at different frequencies of dynamic loading, as well as the impact of this on the vibro-acoustic characteristics of the elastomeric-concrete composites and elastomeric-thermoplastic damping elements for the vibration/noise damping. With the research within the project we contributed to understanding of how the material structure influences on the behaviour of the material in a sense of vibro-acoustic characteristics at different loading velocities and/or frequencies. Implementation of the research results is therefore possible in different fields of elastomeric material applications for anti-impact and vibro-insulation construction elements.
Elastomeric component presents an interesting construction material, particularly since the ecology problem of waste pneumatic tyres is being solved at the same time. With our innovative idea, we shall convert waste articles into high-tech products with high added value using ecologically pure methods.
Significance for the country
In the light of environmental protection there are increasing requirements for noise reduction which in turn creates needs for new load-bearing construction materials with excellent vibro-acoustic properties. Introduction of a new generation of construction materials with superior mechanical and vibro-acoustic properties and exceptional resistance to low temperatures into the manufacture of roadside noise reducing barriers, railway sleepers (railway line foundation work) and dampers represents technological potential for increasing the competitive capacity and added value of Slovenian industrial products.
Newly developed composites offer superior adaptive vibro-acoustic properties and form complementary elements when it comes to the strength properties. Elastomeric-thermoplastic composites have excellent noise absorptive properties. Their application is possible for constructing the elements for anti-noise and anti-vibrations protection. It is possible to apply developed elements as anti-vibration blocks along the railways as complementary part to anti-noise barriers, since they together protect the close vicinity of railways from noise and vibrations. Next important application could be protection from the earthquakes by applying elastomeric-concrete blocks as the construction base of buildings.
The implemented project also presents a contribution to the integration of damping elements in the rail fixing system. Currently, there are only few solutions of this kind in practice, which means that the proposed project will provide significant opportunities for the penetration of Slovenian companies into the markets of Europe.
In the particular case of the company SGP Pomgrad – ABI, d.o.o., which cofounded the project, the possibility for penetration into a new market niche provides the opportunity for proactive operations in a market segment that will become competitive all over Europe.
At the same time, the proposed project has an additional environmentally oriented activity of collecting discarded pneumatic tyres which present a considerable ecological problem for the entire European Community and naturally also for Slovenia. With our innovative idea, we shall convert waste articles into high-tech products with high added value using ecologically pure methods.
