Interconnected multi-walled carbon nanotubes reinforced polymer-matrix composites

Fabrication and properties of CNTs reinforced polymeric matrix nanocomposites for sports applications

“…CNTs can also improve the Zaxis properties of composite laminates remarkably by direct reinforcing the matrix, fiber bridging mechanism, and toughening effect [15]. The flexural strength of glass fiber reinforced epoxy (Relevant websites) [12,14] [ 16,17] composite modified with SWNTs treated with dispersing agents Volan and BYK-9076 (proprietary) showed enhancement up to 16% mainly caused by better dispersion of SWNTs in the composite [18]. The CNTs have also improved the properties in carbon fiber/polymer composites.…”

A Micro-Mechanical Model for Elastic Modulus of Multi-Walled Carbon Nanotube/Epoxy Resin Composites

“…The shape and size of the specimens were prepared according to the ASTM standard [12]. The tensile specimen size (165 x 5.3 x 3 mm) was used in dog-bone shaped.…”

“…These exceptional properties (electrical, physical and mechanical) have earned carbon nanotubes the serious consideration of industrial and scientific organizations for possible use in field emission applications (display panels) [12], nano-devices, probes for SPM (scanning probe microscopy), replacing silicon in microcircuits or in multilevel chips, and hydrogen storage. Recent reports have been published on the use of nanotubes in polymer, metallic and ceramic matrix composites.…”

“…Most of these models suppose a homogeneous dispersion of the nanofiller in the matrix. Although in most cases it is very difficult to get a correct distribution of the SWCNTs or MWCNTs in the polymeric matrix [11][12].…”

“…The onset of matrix cracking and the crack growth will be effectively prevented due to the multibranched morphologies of interconnected CNTs, as a result of the mechanical joggling. And more fracture energy will be consumed due to the complex destruction paths, resulting in the improvement of mechanical properties of the polymer composites [10][11][12].…”
