Journal of Nanomaterials (Impact Factor: 1.64). 10/2013; 2013(4). DOI: 10.1155/2013/565401

ABSTRACT

Graphene nanoplatelets (GNPs) are novel nanofillers possessing attractive characteristics, including robust compatibility with most polymers, high absolute strength, and cost effectiveness. In this study, GNPs were used to reinforce epoxy composite and epoxy/carbon fiber composite laminates to enhance their mechanical properties. The mechanical properties of GNPs/epoxy nanocomposite, such as ultimate tensile strength and flexure properties, were investigated. The fatigue life of epoxy/carbon fiber composite laminate with GPs-added 0.25 wt% was increased over that of neat laminates at all levels of cyclic stress. Consequently, significant improvement in the mechanical properties of ultimate tensile strength, flexure, and fatigue life was attained for these epoxy resin composites and carbon fiber-reinforced epoxy composite laminates.

    • "In contrast with the graphene based polymers, very few studies have so far been reported on investigating the effect of GNSs in the properties of composite laminates. According to literature, Shen et al. [17] improved the tensile and flexure strength of Gr-FRP 20% and 9% respectively. In this study, the incorporation of 0.25 wt% GNPs into the epoxy matrix was introduced using ultrasonication method. "

    ABSTRACT: The present study concerns the development of a new class of carbon fiber reinforced polymers (CFRPs) with a nano-modified matrix based on graphene nano-species. The premium target is the increase of the interlaminar fracture toughness of carbon fiber composites enhanced with graphene nano-species under mode I loading. An in-house developed methodology for the dispersion of the nano-fillers and the manufacturing of nano-doped prepregs is analytically described. Three different kinds of CFRP plates, one with neat matrix and two doped with graphene nano-platelets or graphene oxide were manufactured. Several double-cantilever beam coupons were tested for interlaminar mode I fracture toughness characterization under simultaneous recording of Acoustic Emission (AE) activity. The nano-doped composites exhibit a significant increase of the interlaminar strain energy release rate GIC of the order of 50% for the case of graphene nano-platelets. AE findings combined with extensive scanning electron microscopy (SEM) attempt to delineate the fracture process variations and the involved micro-mechanisms at a meso-scale level that explain the differences in the crack propagation process.

    ABSTRACT: Hydrophilic nature of epoxy polymers can lead to both reversible and irreversible/permanent changes in epoxy upon moisture absorption. The permanent changes leading to the degradation of mechanical properties due to combined effect of moisture and elevated temperature on EPON 862, Nanomer I.28E, and Somasif MAE clay-epoxy nanocomposites are investigated in this study. The extent of permanent degradation on fracture and flexural properties due to the hygrothermal aging is determined by drying the epoxy and their clay-epoxy nanocomposites after moisture absorption. Significant permanent damage is observed for fracture toughness and flexural modulus, while the extent of permanent damage is less significant for flexural strength. It is also observed that permanent degradation in Somasif MAE clay-epoxy nanocomposites is higher compared to Nanomer I.28E clayepoxy nanocomposites. Fourier transform infrared (FTIR) spectroscopy revealed that both clays retained their original chemical structure after the absorption-desorption cycle without undergoing significant changes. Scanning electron microscopy (SEM) images of the fracture surfaces provide evidence that SomasifMAEclay particles offered very little resistance to crack propagation in case of redried specimens when compared to Nanomer I.28E counterpart. The reason for the observed higher extent of permanent degradation in Somasif MAE clay-epoxy system has been attributed to the weakening of the filler-matrix interface.

    ABSTRACT: The control of the nanostructure and the addition of nanoparticles to polymers have led to structural and functional property enhancements in a number of polymeric systems as a material answer to continuous requirements from advanced industrial sectors. The availability of new nanoparticles with extraordinary properties (i.e. carbon nanotubes, graphenes, but also nanoclays, nanocellulose, metals and ceramics) have determined new and exciting possibilities for a continuous enlargement of polymer markets. However, the potentialities of these new materials are still strongly dependent on the development and scaling-up of reliable processing routes. Therefore, the purpose of this report is to review the main processing approaches for nanostructured polymers and nanocomposites starting with a brief review of available nanoparticles and on their functionalization to promote a better polymer–particle interaction. Regarding processing, the review firstly addresses the bottom-up approaches typically adopted for nanostructured polymers, blends and copolymers. Then, the different technologies required by the top-down processing of thermoplastic and thermosetting polymer matrix systems are reviewed. Finally, the report addresses the recent applications of nanostructured polymers and nanocomposites as matrices of advanced composite materials. In all cases, the main processing approaches and the main structural and functional properties characterizing these materials and their potential and current industrial applications are specifically addressed.
