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.

选择三明治结构的复合材料作为运输工具的案例研究

现代运输工具越来越多地使用三明治结构。除其他事项外，造成这种状况的原因包括减轻了运输工具的重量，从而提高了燃油经济性和价格。这项工作致力于对各种材料和三明治设计对其机械性能的影响进行系统的实验研究。在实验框架中，夹心结构的复合材料承受两种类型的应力：静态应力和冲击应力。根据ASTM C-393标准进行了制备样品的测试，特别涉及夹心复合材料结构的弯曲行为以及在ISO 6603-2标准测试范围内的冲击测试。在本文中，我们将对八种核心材料进行静态和冲击测试，
