Impact modified epoxy/montmorillonite nanocomposites: synthesis and characterization

Morphological and Thermal Properties of Cellulose Nanofibrils Reinforced Epoxy Nanocomposites

“…The T g values of the nanocomposites showed no appreciable changes among each other compared with their increase over neat epoxy. Isik et al (2003) also observed that the glass transition temperatures of epoxy slightly increased with increasing clay content. This status explained this behavior in terms of the restricted mobility of polymer chains due to the interaction between the particles and the polymer.…”

“…A commercially available Technobond 3000 adhesive epoxy with two components, i.e., a resin and a hardener, was obtained from Techno Structural Chemicals, Turkey. The density of the epoxy adhesive was 1.15 g/cm 3 . The fl ammable point of the epoxy was 180 °C, and the curing time was 45 min.…”

Synthesis and properties of epoxy-phenolic clay nanocomposites

“…This can be attributed to the presence of clay particle agglomerates, noted previously, that act as stress concentrators, diminishing impact strength, and the decreasing capability of matrixes to undergo viscoelastic and/or plastic deformation with increasing strain rate [46] SEM images of fracture surfaces from impact toughness tests are shown in Figure 9. The fracture surfaces of the nanocomposites showed irregular, micro-roughened topography consistent with fast crack growth [46][47][48][49]. Historically, thermosetting resins such as epoxies have key engineering limitations, including inherent brittleness and moisture uptake.…”

Mechanical properties of nanocomposite laminated structure and its sensibility to modal analysis procedure

“…Another attractive aspect of a nanocomposite structure is the reduction of damage due to impact loadings. Among researchers who have studied the effect of nanoparticles, Yasmin et al (2003) and Isik et al (2003) also found an increase in the elastic modulus and toughness.…”
