Abstract
Modern means of transport increasingly utilize sandwich constructions. Among other things, the reasons for such state of affairs include the reduced weight of means of transport, and through this, better fuel economy as well as price. This work is dedicated to a systematic experimental study of the influence of various materials and sandwich designs on their mechanical properties. In the framework of experiments, sandwich-structured composites were exposed to two types of stressing: static as well as impact stressing. The testing of prepared samples was performed according to ASTM C-393 Standard, dealing specifically with the bending behavior of sandwich composite constructions and impact testing under the scope of ISO 6603-2 Standard test. In this article we deal with static and impact testing of the eight types of core materials, two types of coatings, two types of surface finishes, and two types of resins with a special emphasis on their use in constructions of some exterior or interior components of transport means.
Highlights
Because of their specific properties, sandwich constructions are widely used in the industry of transport means, because of the reduced weight of such products
The results showed an improvement of specific strength and elastic modulus with increasing number of carbon fiber-reinforced polymers [31]
The presented case study is focused on useful experimental findings about the mechanical properties of sandwiches that are influenced by materials as well as layer arrangements in the structures of such composites
Summary
Because of their specific properties, sandwich constructions are widely used in the industry of transport means, because of the reduced weight of such products. It stands to reason that their first applications appeared in the aircraft industry. Favorable properties accelerated their further development, and there are unlimited quantities of such materials available on the market. The incessant development of new materials leads to gradual reductions in their prices, which makes sandwich constructions affordable in other transport applications (mainly in ship-building and railway branches), mainly because of another advantage—specific rigidity. This is rather advantageously exploited in large-area products, i.e., for various cladding purposes (either interior or exterior, ceiling panels, bulkheads, floor panels, etc.). If composite shaping properties for coating of sandwich constructions are used, the sandwich material may represent even the product design
