Scrap car tyre particles can be used as filler or toughening agent in rigid epoxy matrices if the resultant interface is adequate. The objective of this work was to investigate the effects of use of different silane coupling agents (SCAs) to improve the interface between the epoxy resin and recycled rubber particles. For this purpose, seven different SCA were used to modify surfaces of the rubber particles. After the preparation of epoxy-rubber specimens, tensile Charpy impact and plane-strain fracture toughness tests were conducted. Mechanical tests and fractographic studies revealed that some of the SCA can improve of the interface between the epoxy matrix and the rubber particles leading to increases in strength while slight decreases in toughness of the samples.

Interface studies between epoxy and recycled rubber
Sipahi-Saglam, E; Kaynak, Cevdet; Akovali, G (2000-07-19)
This work covers studies on interfaces between epoxy and recycled rubber used as toughening phase in epoxy resins. Different surface modification techniques were used to improve the compatibility at the interface between the rubber particles and the epoxy matrix. Silane coupling agents, plasma surface modification and acrylic acid/benzoylperoxide were used to enhance the surface properties of rubber particles. Rubber parts of grinded scrap car tyres with a size range of 355-500 mum after surface treatment w...
Preparation and characterization of micron size serpentine filled abs composite
Alakoç, Mustafa Can; Tinçer, Teoman; Department of Polymer Science and Technology (2008)
Micron size non-treated / silane coupling agent (SCA) treated serpentine filled acrylonitrile-butadiene-styrene (ABS) composite preparation and characterization of composites in terms of mechanical, thermal, flow properties and morphology were studied in this work. First step of the study was the size reduction of the as collected serpentine mineral. Secondly, three types of silane coupling agent treatments were applied to serpentine which were gamma-methacryloxypropyltrimethoxysilane (A-174), beta-(3,4-epo...
A fractographic study on toughening of epoxy resin using ground tyre rubber
Kaynak, Cevdet; Akovali, G. (2001-01-01)
This study is a fractographic examination of epoxy resin modified with scrap car tyre regrinds used as toughening phase. Five different surface treatment techniques, used to improve the compatibility at the interface between the rubber particles and the epoxy matrix, were: oxygen plasma, two silane coupling agents, acrylic acid and acrylic acid/benzoylperoxide mixture. Rubber parts of ground scrap car tyres with a size range of 355-500 mum after surface treatment were mixed with epoxy. This mixture was pour...
Effect of variable friction coefficient on sheet metal drawing
Darendeliler, Haluk; Yucesoy, CA (Elsevier BV, 2002-02-01)
A variable friction model that relates the parameters of sheet metal drawing to the local lubrication conditions taking place during the deformation, has been integrated to a finite element program. Variable friction coefficients for the contacting surfaces are determined from the friction model, which uses the related parameters obtained at each time step of the finite element program as inputs. A number of numerical runs have been performed and the strains are compared with the experimental results for ci...
Analysis of specimen size effects in inclined compression test on laminated elastomeric bearings
Topkaya, Cem (Elsevier BV, 2004-07-01)
Inclined compression test method is a practical way of determining the shear modulus of full-size laminated elastomeric bearings. Performing full-size bearing tests requires high-capacity testing machines. It may be possible to cut the specimens into smaller sizes for testing purposes. Limited amount of experimental data show that specimen size has a significant effect on the measured shear modulus. In this paper, the Haringx shear weak column theory is used to identify the important geometric specimen prop...
