The influence of silicate-based nano-filler on the fracture toughness of epoxy resin

Epoxy‐Based Fibre Reinforced Nanocomposites

“…Lower nanoclay concentrations resulted in a relatively insignificant reduction in microcracking and higher concentrations displayed a traditional filler effect. In a recent development, Brunner et al [84] exploited Timmerman et al [83] work on use epoxy with a relatively small amount of nano-size filler as matrix in fibre-reinforced laminates. They focused on investigating whether a nano-modified epoxy matrix yields improved delamination resistance in a fibre-reinforced laminate compared to a laminate with neat epoxy as matrix material.…”

“…They focused on investigating whether a nano-modified epoxy matrix yields improved delamination resistance in a fibre-reinforced laminate compared to a laminate with neat epoxy as matrix material. [84] To start with, neat and nano-modified epoxy specimens without fibre reinforcement were prepared for a comparison of the fracture toughness of the matrix material itself. Additional properties of the neat and nano-modified epoxy were REVIEWS also determined (partly taken from Timmerman et al [83] ) and compared.…”

Fracture and toughening mechanisms of GNP-based nanocomposites in modes I and II fracture

“…As a result, various types of nanofillers (such as rubber particles and nanoclays), have been added to epoxies in an attempt to increase their toughness. Although these nanofillers have shown to improve the toughness of epoxy resins significantly, but it has been observed that in turn, they could also degrade the stiffness of the reinforced epoxy resins [1,2] by a notable margin.…”

Fracture Behavior of GFRP Laminates with Nanocomposite Epoxy Resin Matrix

“…The epoxy resin system was identical to that of a previous study [8] showing promising potential but the organo-silicate used for modification was different because of limited availability of the custom made clay used in Refs [6,8].…”
