Design of Cost Effective Epoxy + Scrap Rubber Based Composites Reinforced with Titanium Dioxide and Alumina Fibers
Mechanics of Composite Hybrid and Multifunctional Materials Volume 5, 2018Co-Authors: A. B. Irez, Ibrahim Miskioglu, Ekrem BayraktarAbstract:In last decades, aerospace and automotive industries are in search of multi-functional high performance, low cost materials due to certain environmental regulations. Epoxy-recycled Rubber based structural composites (ERCs) are used in these type of engineering applications thanks to their favorable properties such as corrosion resistance, low cost and light weight. In addition, the use of recycled materials gives an economic and environmental aspect to the manufacturers. The data for basic material parameters of these composites is essential in order to realize an efficient engineering development process. For this reason, this paper is focused on the design of ERCs reinforced with ceramic powders in different ratios in a matrix of epoxy-fresh Scrap Rubber. The mechanical and some physical properties of these composite systems were studied in this research. Titanium dioxide (titania-TiO2) and alumina fibers (Al2O3) are used as reinforcements in pre-defined weight percentages. During this study, mechanical and wear properties of these composite systems are studied. Three-point bending tests and nanoindentation were conducted to evaluate mechanical properties. After that, wear resistance is examined by means of nano-scratch tests. As the final step, fracture surfaces were observed with scanning electron microscopy (SEM) to identify damage mechanisms of these composites.

mechanical characterization of epoxy Scrap Rubber based composites reinforced with alumina fibers
2018Co-Authors: A. B. Irez, Emin Bayraktar, Ibrahim MiskiogluAbstract:Recently, encouraged by the idea of sustainable development, the emissions of CO2 have become a very prominent issue to be solved. As a consequence, in the automotive and aeronautic industries, the reduction of weight has become a major issue and needs to be addressed for all possible structures in the vehicle. Therefore, some metallic parts are being replaced by polymer based composites. For this to happen, the feasibility of using these composites has to be examined properly in terms of their mechanical and energetic properties. Epoxy – Rubber based composites reinforced with ceramics are studied by several researchers. However, addition of Scrap Rubber to the matrix and alumina fibers (Al2O3) as a reinforcement introduces a novelty in this area. Since, using of Scrap Rubber has positive outcomes in economical and structural perspectives such as revaluation of Scraps and compensating the brittleness of epoxy. Also, due to its favorable structural characteristics such as interlocking properties of fibers, addition of alumina fibers ensures desired mechanical properties in case of a homogeneous distribution. This paper is focused on the design of epoxy – fresh Scrap Rubber matrix reinforced with different ratios of alumina fibers. The mechanical and some physical properties of these composite systems were studied in this research. Mechanical properties were evaluated by means of drop weight tests, three-point bending tests and nanoindentation technics. Scanning electron microscope (SEM) was used to observe fracture surfaces and the microstructure. After all, UV degradation of the material was observed by electron microscopy.

structure and mechanical properties of srp hdpe poe epr or epdm composites
Polymer Testing, 2003Co-Authors: Yipo Li, Yinxi ZhangAbstract:The effects of dicumyl peroxide (DCP) and ethylene-octylene copolymer (POE), ethylene-propylene copolymer (EPR) or ethylene-propylene-diene terpolymer (EPDM) on the structure and properties of Scrap Rubber powder (SRP)/high-density polyethylene (HDPE) composites were studied. Torque and gel content results show that DCP promotes crosslinking of the SRP/HDPE/POE (EPR or EPDM) composites. The SRP/HDPE/POE (EPR or EPDM) composites containing a small amount of DCP have better mechanical properties than their corresponding composites without DCP. Highest tensile strength and elongation at break are found in the dynamically vulcanized SRP/HDPE/POE composite. Scanning electron microscopy (SEM) results show that good bonding between SRP and matrix is formed in the SRP/HDPE/POE (EPR or EPDM) composites with DCP.

mechanical properties of high density polyethylene Scrap Rubber powder composites modified with ethylene propylene diene terpolymer dicumyl peroxide and silicone oil
Journal of Applied Polymer Science, 2003Co-Authors: Yan Li, Yong Zhang, Yinxi ZhangAbstract:The effect of ethylene–propylene–diene terpolymer (EPDM), dicumyl peroxide (DCP), and dimethyl silicone oil on the mechanical properties of high-density polyethylene (HDPE) composites filled with 60 mesh cryogenically Scrap Rubber powder (SRP) was studied. The addition of 10 wt % EPDM, 0.2 wt % DCP, and 4 wt % dimethyl silicone oil significantly increased both the impact strength and elongation at break of the HDPE/SRP composites. After the modification, the impact strength increased by 160%, and the elongation at break increased by 150% for the composites containing 40 wt % SRP. The impact load–time curves showed that the increase of impact energy for the modified composites was attributed to the increase of the maximum force at yield point and the ductile deformation after yielding. The rheological behavior, dynamic mechanical properties, and morphology observation suggested that an enhanced adhesion between SRP and polymer matrix formed in the modified HDPE/SRP composites. © 2003 Wiley Periodicals, Inc.

vulcanization characteristics and mechanical properties of natural Rubber Scrap Rubber compositions filled with leather particles
Polymer International, 2005Co-Authors: K Ravichandran, N. NatchimuthuAbstract:Scrap Rubber recycling combined with waste leather particles in natural Rubber compounds has been studied. The effect of leather and Scrap Rubber loading on vulcanization characteristics of natural Rubber compounds has been evaluated. The presence of leather was found to reduce the scorch time and increase the maximum and minimum torque. While reversion was not observed in the absence of leather at 150 °C, it was more prominent when leather was incorporated. Mechanical properties such as tensile strength, elongation at break, tear strength, modulus and hardness were found to increase on increasing the Scrap Rubber loading in the absence of leather. Compounds containing leather exhibited higher tensile strength, modulus, hardness and tear strength values but the modulus and hardness values were found to decrease as the Scrap Rubber loading increased. All the vulcanizates exhibited only limited swelling in different media as the swelling of one phase of the composite was found to be restricted by the other phase.

Natural Rubber: leather composites
Polímeros, 2005Co-Authors: Krishnan Ravichandran, N. NatchimuthuAbstract:Leather is a fibrous protein consisting of collagen in a three dimensionally crosslinked network. Chrome tanning of leather improves the appearance of leather but at the same time emits both solid and liquid chrome leather wastes. Scrap Rubber recycling using untreated and neutralized leather fibrous particles in natural Rubber has been studied. Vulcanization, mechanical, morphological and swelling properties of the natural Rubber - Scrap Rubber composites containing neutralized leather have been discussed. Use of chrome leather particles has been found to improve the consumption of Scrap Rubber powder in natural Rubber formulations. Polymer composites based on leather wastes as fillers are reported to be useful for many applications such as in construction materials, automobile interior moldings, heat and sound insulating boards, shoe soles, flooring materials and moldings with good anti-static properties, air permeability and good appearances.

viscous properties storage stability and their relationships with microstructure of tire Scrap Rubber modified asphalt
Construction and Building Materials, 2015Co-Authors: Ming Liang, Baodong XingAbstract:Abstract Recycled-polymer modified asphalt has been extensively used in road construction, especially the recycled tire Scrap Rubber-modified asphalt (TSRMA). However, the main problem during the application of TSRMA is poor storage stability which finally affects the service performance of the pavement. The objective of this work is to evaluate viscous properties, storage stability and morphology of TSRMA and to reveal the relationship of microstructure with rheological behavior and storage stability. With this aim, two different penetration grade asphalts were modified by Rubber particles with various mean diameter in a four-paddle mixer at 170 °C. Steady state flow measurements, frequency sweep tests in linear viscoelastic region, storage stability tests as well as fluorescence microscopy were carried out on mixes. Rheological evaluation reveals that the addition of tire Scrap Rubber to asphalt lead to a significant increase in viscosity at 60 °C, improving rutting or permanent deformation resistance. Furthermore, the increase in particle size causes an enhancement in viscosity and the steady flow behavior tend to turn into non-Newtonian fluid with increasing particle size and temperature. Storage tests presented that the viscosity of samples obtained from the bottom section of a tube are always higher and the difference also becomes significant as the increase of Rubber particles size, tending to poor stability. Fluorescence microscopy shows that dispersed particles in asphalt are the elongated features or strip-type and the aspect ratio (length/diameter) increases with particle size. In addition, smaller particle tend to be unobvious in matrix under microscopy view, indicating improved compatibility between Rubber and asphalt.
