Modeling and optimization of a new impact-toughened epoxy nanocomposite using response surface methodology

Characteristics and Properties of TiO2/EP‐PU Composite

“…Generally, TCA201-TiO 2 modified by coupling agent was not simply physically blending with polymer matrix. TCA201-TiO 2 and polymer matrix could form chemical bonds through coupling agent; as the surface of TCA201-TiO 2 has existed in much active groups, these groups could improve fracture energy and adhesive strength of the composites [10]. The structure of coupling agent had two kinds of functional group; one was active group and the other was nonactive group; this structure would play the role of a bridge which associated with the nano-TiO 2 and the epoxy matrix.…”

Modeling and Analysis of the Tensile and Flexural Properties of a Fiber-Orientated Hybrid Nanocomposite Using Taguchi Methodology

“…Geisler and Kelley [28] filled epoxy resin with alumina (Al 2 O 3 ) and rubber particles and reported that obtained toughness values were 25% higher than those of epoxy systems having only alumina (Al 2 O 3 ) or rubber particles. Mirmohseni and Zavareh [29] showed that by adding 2% clay and 20% polyamide, the material toughness increased by 115% and also impact strength improved as compared to neat epoxy. Kinloch et al [30] added nanosilica and rubber microparticles to epoxy resin.…”

Experimental study on the mechanical properties of an epoxy-based nanocomposite using polymeric alloying and different nano-reinforcements: nanofiber, nanolayered and nanoparticulate materials

“…An alternative approach for improving the mechanical properties of epoxy resins is adding rigid inorganic nanoparticles without affecting the glass transition temperature of the epoxy. Various nanofillers, such as silica (SiO 2 ) [18 -21] , alumina (Al 2 O 3 ) [22] and titania (TiO 2 ) [23,24] , are also employed for this purpose. Incorporation of inorganic nanofillers improves the fracture toughness to some extent.…”
