“…In addition, it was reported that cup-stacked carbon nanotubes (CSCNT) used in both epoxy matrix and the interface of CFRP sublaminates increased the fracture toughness by threefold [9]. Also, the addition of a CNT enhanced non-woven carbon tissue interleaf to the interface of CFRP sublaminates increased the Mode-I and Mode-II fracture toughnesses with 35.3% and 246%, respectively [12]. Although these nanofillers can effectively enhance the interlaminar mechanical properties of CFRP laminates, they are generally expensive which impede their extensive applications.…”

“…Among various nanofillers, carbon based nanofillers such as carbon nanotube (CNT) [9,12], vapor grow carbon fiber (VGCF) [8,10], graphene and its oxide [13,14] etc., were widely employed. For example, it was shown that the addition of 20 g/m 2 VGCF into the interface of two CFRP sublaminates could increase the Mode-I fracture toughness by 95.5% [8].…”

“…According to [18], the increase of the IFSS due to the addition of MWCNTs can explain the increase of the interlaminar shear strength (ILSS). The addition of MWCNTs to the resin or to the FRCs also increases the material fracture toughness of the material, as demonstrated in [19] or [20] for epoxy resin and in [21][22][23][24] for FRCs (glass fiber and carbon fiber reinforcement).…”

This work investigates the effect of multiwall carbon nanotubes (MWCNTs) on the mechanical and tribological behavior of a fiber reinforced composite (FRC). Fiber reinforced composites and nano-engineered FRCs are manufactured by resin transfer molding. In-plane tensile tests, in-plane shear tests and through-thickness compression tests are used to assess the influence of MWCNTs on the material mechanical behavior. Pin on disk dry sliding tests are used to quantify the effect of MWCNTs on the friction coefficient and the specific wear rate. It was determined that (1) MWCNTs have an influence on the improvement on both the through-thickness compression strength and the specific wear rate, and (2) they do not influence the material stiffness, in-plane tensile and shear strengths and the friction coefficient. It is assumed that the observed improvements are due to the demonstrated positive influence of the MWCNTs effect on the matrix/reinforcement interfacial strength and on the matrix fracture toughness.

“…Zheng et al used carbon nanotubes/polysulfone nanofiber prepared by vacuum filtration as the toughening interleaf [27]. Lee et al used CNT-enhanced nonwoven carbon tissue as the interleaf and found a significant improvement of G IIC [28]. Although the functions of the materials in these references were not studied, the multi-scale toughening mechanism of different material systems was interesting and still needed to be further explored.…”

Abstract:The effect of plant-fiber paper or silver nanowires-loaded paper interleaves on the electrical conductivity and interlaminar fracture toughness of composites was studied. Highly conductive paper was prepared by surface-loaded silver nanowires. The percolation threshold appeared at about 0.4 g/m 2 . The surface resistivity reached 2.3 Ω/sq when the areal density of silver nanowires was 0.95 g/m 2 . After interleaving the conductive papers in the composite interlayers, in-plane electrical conductivity perpendicular to the fiber direction was increased by 171 times and conductivity through thickness direction was increased by 2.81 times. However, Mode I and Mode II interlaminar fracture toughness decreased by 67.3% and 66.9%, respectively. Microscopic analysis showed that the improvement of conductivity was attributable to the formation of an electrical conducting network of silver nanowires which played a role in electrical connection of carbon fiber plies and the interleaving layers. However, the density of the highly packed flat plant fibers impeded the infiltration of resin. The parallel distribution of flat fibers to the carbon plies, and poor resin-fiber interface made the interlaminar fracture occur mainly at the interface of plant fibers and resin inside the interleaves, resulting in a decline of the interlaminar fracture toughness. The surface-loading of silver nanowires further impeded the infiltration of resin in the densely packed plant fibers, resulting in further decline of the fracture toughness.
