Processing a glass fiber reinforced vinyl ester composite with nanotube enhancement of interlaminar shear strength

Development Of Multistitched Three-Dimensional (3D) Nanocomposite And Evaluation Of Its Mechanical And Impact Properties

“…The aminefunctionalized single-wall carbon nanotubes (a-SWCNTs) incorporated at the fiber/fabric-matrix interfaces of a 2D woven carbon/epoxy composite showed improvement in the tensile strength-stiffness and the tensile-tensile fatigue damage [16]. It was claimed that the predispersed over-coating nanotubes and the processing modification led to the enhancement of the interface properties of 2D woven E-glass/vinyl ester composites partly because of Z-directional reinforcements [17]. It was also found that nanotubes with amine functional groups have better tensile strength, as compared to those with untreated carbon nanotubes (CNTs) [18].…”

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

“…The CNTs can decelerate the delamination crack propagation by CNTs pull-out and fracture, and crack bridging [13]. Glass fiber reinforced epoxy and epoxy based vinyl ester composites were modified with CNTs and studied for interfacial [14] and interlaminar shear strength [15]. 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].…”

Mechanical Characterization of Mesoscale Interfaces Using Indentation Techniques

“…[21][22][23][24] In polymer composites, significant effort has been focused on improving wettability and chemical bonding at or near the interface region. [25][26][27][28][29][30][31][32] Generally referred as the interphase, this region exhibits a transition between the properties of the matrix and the reinforcement phases. Engineering these interphases for improved macroscale properties presents a significant challenge.…”

“…Engineering these interphases for improved macroscale properties presents a significant challenge. Prior efforts have included silane treatments of glass fiber epoxy composites, 25,26 use of nanotubes to enhance glass fiber-matrix adhesion, 28 the use of nano-fillers in the matrix, 33 and surface modifications of carbon nanotubes. 27 Although these studies have clearly demonstrated the enhancement of the bulk mechanical properties, additional work is still needed to understand and quantify the underlying physical processes.…”
