“…This is because, in general, such resins inherently have low strain capacity in comparison to the limiting strain of the fibers they commonly host, low fracture toughness [1], and weak fiber/matrix interface bond strength [2]. As a result, various types of nanoparticles, such as carbon nanotubes (CNTs), have been included in epoxies in an attempt to enhance their toughness [3][4][5]. Indeed, CNTs have been widely used to enhance the fracture response of FRP under modes I and II fracture [6][7][8][9].…”

“…In PMCs, thermosetting epoxy is the most commonly used matrix [4][5][6][7]. The damage tolerance and fracture toughness of epoxy can be enhanced with the incorporation of (nano-) fillers such as metallic oxides [8][9][10], clays [11][12][13], carbon nanotubes (CNTs) [14][15][16], and other carbonaceous materials [17][18][19]6,5]. When nanofillers are introduced in polymers, the fracture pattern significantly changes due to the defection of advancing cracks with strong nanofillers.…”

Abstract:The topographical features of fractured tensile, flexural, K1C, and impact specimens of 1.0 wt% Multi-Layer Graphene (MLG)/nanoclay-epoxy (EP) nanocomposites have been investigated. The topographical features studied include maximum roughness height (Rmax or Rz), root mean square value (Rq), roughness average (Ra), and waviness (Wa). Due to deflection and bifurcation of the cracks by nanofillers, specific fracture patterns are observed. Although these fracture patterns seem aesthetically appealing, however, if delved deeper, they can further be used to estimate the influence of nanofiller on the mechanical properties. By a meticulous examination of topographical features of fractured patterns, various important aspects related to fillers can be approximated such as dispersion state, interfacial interactions, presence of agglomerates, and overall influence of the incorporation of filler on the mechanical properties of nanocomposites. In addition, treating the nanocomposites with surfaces of specific topography can help improve the mechanical properties of nanocomposites.

“…The first manufactured PMCs used glass fibers as reinforcement. Besides glass fibers, some frequently used reinforcements include metallic oxides [2]- [4], clays [5]- [7], Carbon Nanotubes (CNTs) [8]- [10], and other carbonaceous materials [11]- [13]. The trends of the use of various reinforcements in the last decade are shown in Figure 2.…”

Modeling and simulation allow methodical variation of material properties beyond the capacity of experimental methods. The polymers are one of the most commonly used matrices of choice for composites and have found applications in numerous fields. The stiff and fragile structure of monolithic polymers leads to the innate cracks to cause fracture and therefore the engineering applications of monolithic polymers, requiring robust damage tolerance and high fracture toughness, are not ubiquitous. In addition, when "many-parts" cling together to form polymers, a labyrinth of molecules results, which does not offer to electrons and phonons a smooth and continuous passageway. Therefore, the monolithic polymers are bad conductors of heat and electricity. However, it is well established that when polymers are embedded with suitable entities especially nano-fillers, such as metallic oxides, clays, carbon nanotubes, and other carbonaceous materials, their performance is propitiously improved. Among various additives, graphene has recently been employed as nano-filler to enhance mechanical, thermal, electrical, and functional properties of polymers. In this review, advances in the modeling and simulation of grapheme based polymer nanocomposites will be discussed in terms of graphene structure, topographical features, interfacial interactions, dispersion state, aspect ratio, weight fraction, and trade-off between variables and overall performance.
