Mechanical Characterization of Epoxy: Scrap Rubber Based Composites Reinforced with Nanoparticles

Epoxy rubber based structural composites (ERCs) are used in engineering applications mainly in the aeronautical area because they can meet the necessary requirements in new multifunctional systems. These composites exhibit good overall mechanical and thermal performance and they can potentially offer a large variety of functional properties. In order to realize an efficient engineering development process, the data for basic material parameters of these composites is essential. The present paper discusses the mechanical characterization of these composites. A combination of structural and energetic functions can be achieved by using different nanoparticle reinforcements in epoxy-rubber composites This type of material design gives an exigent task to the designers looking to integrate more functionality into the base material of their structure to achieve overall improved system performance. This paper is focused on the design of ERCs reinforced with nano powders in different ratios in a matrix of epoxy – fresh scrap rubber. It is expected this material would be attractive for industrial applications because of the readily available recycled materials that are utilized. The mechanical and some physical properties of these composite systems are studied in this research. Mechanical properties are evaluated by means of three-point bending tests, nano-indentation, drop weight tests and dynamic mechanical analysis. Scanning electron microscope is used to observe fracture surfaces and the microstructure.
