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 poured into molds to obtain fracture toughness test specimens. After curing, plane strain fracture toughness tests were performed and the fractured surfaces of the specimens were examined under the scanning electron microscope. Fractographic studies indicated that the increase in fracture toughness values were due to the improved interface leading to crack deflection as the main rubber toughening mechanism. Secondary rubber toughening mechanisms observed were shear deformation and some debonding initiated at the interface. (C) 2001 Elsevier Science Ltd. All rights reserved.

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...
Studies on epoxy modified with recycled rubber
Sipahi-Saglam, E; Kaynak, Cevdet; Akovali, G; YETMEZ, MEHMET; AKKAŞ, NURİ (Wiley, 2001-03-01)
This work covers studies on systems with car tire regrind used as the 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 ground used car tires, with or without surface treatment, were mixed with epoxy. This mixture ...
A micro-continuum-mechanical material model for failure of rubber-like materials: Application to ageing-induced fracturing
Dal, Hüsnü (2009-08-01)
Rubbery polymers are subjected to severe environmental conditions under service. As a consequence of various ageing mechanisms, the outer surface of rubber components hardens in time and cracking occurs as a result of combined mechanical and chemical processes. Conventional phenomenological hyperelastic constitutive models do not account for material softening. Consequently, the stored energy and stresses tend to infinity as stretch increases. In this contribution, a network alteration for the ageing mechan...
A study on the constitutive equation effects in the fracture initiation of AA5450 sheets
Dizaji, Shahram A.; Darendeliler, Haluk; Kaftanoğlu, Bilgin (2019-01-01)
© Springer Nature Singapore Pte Ltd. 2019.Determination of the fracture initiation in the sheet metal forming applications can be achieved successfully using ductile fracture criteria (DFCs) and finite element codes together. In this study three different uncoupled, energy based ductile fracture criteria have been employed to predict the onset of the fracture in the AA5450 aluminum alloy sheets. Also, two different constitutive models namely, isotropic von-Mises and anisotropic Hill, have been implemented t...
Modification of epoxy by a liquid elastomer and solid rubber particles
ÇELİKBİLEK, CENGİZ; AKOVALI, GÜNERİ; Kaynak, Cevdet (2004-04-01)
This work covers studies on epoxy resin systems modified with two different rubber phases. The first modification was the use of recycled car tire rubber particles; while in the second one a silicon based liquid elastomer (Tegomer) was mixed with the epoxy resin matrix. In the third method epoxy resin was modified with both solid rubber particles and liquid elastomer together.
