“…Dadfar et al the mode I interlaminar fracture toughness (G Ic ) of the glass epoxy laminates increased from 220 J/m 2 to about 500 J/m 2 whereas the elastic modulus and tensile strength went down from 28.4 GPa to 17.8 GPa and 584 MPa to 489 MPa respectively [12]. More recently, the effect of nanoparticles such as nanoclay, carbon nanotubes, nanowhiskers and vapour grown carbon nanofibres on the toughness of the epoxy matrix has been studied [13][14][15]. Although an increase in bulk fracture toughness could often be accomplished by adding these additional components to the epoxy matrix, the absolute increase in interlaminar fracture toughness of the composite laminates remains moderate at best [16][17][18].…”

Delamination and brittle matrix fracture has since long been a problem of fibre reinforced composites. This paper investigates if polycaprolactone (PCL) nanofibre nonwovens can increase the interlaminar fracture toughness of resin transfer moulded glass fibre/epoxy laminates, without causing problems during impregnation and without negatively affecting other (mechanical) properties.The mode I fracture toughness was shown to be dependent on both the nanofibre content as well as on how the nanofibres were introduced into the laminates. Almost 100% improvement in fracture toughness could be achieved by electrospinning the PCL nanofibres on both sides of the glass fibre mats prior to impregnation. This led to a mode I fracture toughness of over 1200 J/m 2 . 2Tensile and dynamic mechanical properties of the toughened laminates were not affected by the PCL nanofibres. It could be concluded that even state of the art infusion resins with a high intrinsic fracture toughness can benefit significantly from nanofibre toughening.

“…When properly dispersed in a polymer matrix material, CNTs could allow for improvement in fracture toughness and fatigue properties since the CNT size is on the same order as defects in the material [4]. Many researchers have shown that the addition of a small volume fraction of CNTs to various polymers can improve the bulk modulus of the composite materials such as epoxy [5], polyimide [6], polyethylene [7], methyl-ethyl ethacrylate [8], or polyvinyl alcohol [9].…”

“…Better interfacial strength, especially shear strength, is important to improve the nanocomposites bulk properties [17]. However, to date, only a few techniques [18][19][20] are able to directly measure the interfacial fracture energy between an individual CNT/nanofiber and surrounding matrix despite recent calls for individual fragment, pulling, and peeling experiments between polymers and CNTs/nanofibers [4].…”

Byron; Nguyen, Cattien V.; and Raman, Arvind, "Interfacial energy between carbon nanotubes and polymers measured from nanoscale peel tests in the atomic force microscope" (2009 b s t r a c tThe future development of polymer composite materials with nanotubes or nanoscale fibers requires the ability to understand and improve the interfacial bonding at the nanotube-polymer matrix interface. In recent work [Strus MC, Zalamea L, Raman A, Pipes RB, Nguyen CV, Stach EA. Peeling force spectroscopy: exposing the adhesive nanomechanics of one-dimensional nanostructures. Nano Lett 2008;8(2):544-50], it has been shown that a new mode in the Atomic Force Microscope (AFM), peeling force spectroscopy, can be used to understand the adhesive mechanics of carbon nanotubes peeled from a surface. In the present work, we demonstrate how AFM peeling force spectroscopy can be used to distinguish between elastic and interfacial components during a nanoscale peel test, thus enabling the direct measurement of interfacial energy between an individual nanotube or nanofiber and a given material surface. The proposed method provides a convenient experimental framework to quickly screen different combinations of polymers and functionalized nanotubes for optimal interfacial strength.Published by Elsevier Ltd.
