Mechanical and Tribological Properties of Scrap Rubber Based Composites Reinforced with Glass Fiber, Al and TiO2 L.M.P. Ferreira, I. Miskioglu, E. Bayraktar, and D. Katundi Abstract Scrap rubber/Epoxy composites reinforced with Aluminium, Glass Fibre (GF) and TiO2 particles were prepared and mechanical and tribological properties of these composites were investigated. Basically, these composites are aimed to use in automotive and aeronautics applications. A detail microstructure and matrix/reinforcement interface analyze was made by means of Scanning Electron Microscope (SEM) The wear performance of hard particles reinforced composites were evaluated. Quasi static and dynamic compression tests were carried out and damaged specimens were studied by SEM. The hardness (short test) values of the composites were reviewed related to the reinforcement elements, Glass Fibre-fiber and TiO2 added in the matrix. Keywords Recycling materials • Rubber/epoxy composites • Low-cost engineering • Wear resistance

Introduction
In engineering applications, there are many possibilities for usage of recycling of scrap rubber and most of them are used in automotive industry and domestic area, etc. Other main areas such as the aerospace and microelectronics industries have enourmous demand for high performance (ductile and high toughness) structural adhesive systems like epoxy and/or elastomers reinforced composites [1–9]. Today, additionally, the main component of these waste rubbers is styrene– butadiene rubber (SBR) and, in spite of the different uses for recycling it, the research for new applications is still a need because of the extremely high amount of waste rubber produced every year [5–8, 10–16]. Additionally, these materials are commonly used for long term applications at ambient or at moderately elevated temperature conditions. Conforming to these needs, elastomers (rubbers) should be used by simple processing with various materials in different conditions by addition of new alloying elements [7–11]. The present work reviews manufacturing facilities of scrap elastomers (SBR-rubbers) + epoxy resin composites with different proportions of particulate reinforcements. Main objective of this research was to determine the ductility and toughness of scrap elastomer (SBR rubber) matrix composites containing GF, TiO2, B, etc. as basic reinforcements. Basically, these composites are aimed to use in automotive and aeronautics applications as bumpers and as internal furniture as ductile and tough and sound materials. Scanning electron microscopy (SEM) was used to study the microstructure and fracture surfaces of these composites.
