Nanomaterials: Opportunities and Challenges for Aerospace

2005

: Nanomaterials are regarded world-wide as key materials of the 21st Century. Also, in aerospace a high potential for nanomaterials applications is postulated and technological breakthroughs are expected in this area. In this context, improvements based on these materials are to be considered both in a short to medium-term time scale as well as on a long-term basis in view of different prospective studies. Some applications are feasible in a short to medium-term time horizon like: (a) lightweight and mechanically outstanding structures based on nanocomposites, especially for harsh environments and high temperatures; (b) improved and smaller systems and controls based on microsensors, on smart nanomaterials, and/or on embedded actuators for on-line monitoring, self-calibration, self-regulation, or self-healing applications; (c) Thermal and mechanical protection layers with outstanding tribological characteristics for engine or landing gear parts made of nanostructured materials; (d) ...

Nanocomposites as Advanced Materials for Aerospace Industry

INCAS BULLETIN, 2012

Polymer nanocomposites, consisting of nanoparticles dispersed in polymer matrix, have gained interest due to the attractive properties of nanostructured fillers, as carbon nanotubes and layered silicates. Low volume additions (1-5%) of nanoparticles provide properties enhancements comparable to those achieved by conventional loadings (15-40%) of traditional fillers. Structural nanocomposites represent reinforcement structures based on carbon or glass fibers embedded into polymeric matrix modified with nanofillers. Structural composites are the most important application of nanaocomposites, in aerospace field, as, laminates and sandwich structures. Also, they can by used as anti-lightning, anti-radar protectors and paints. The paper presents the effects of sonic dispersion of carbon nanotubes and montmorrilonite on the mechanical, electrical, rheological and trybological properties of epoxy polymers and laminated composites, with carbon or glass fiber reinforcement, with nanoadditivated epoxy matrix. One significant observation is that nanoclay contents higher than 2% wt generate an increase of the resin viscosity, from 1500 to 50000-100000 cP, making the matrix impossible to use in high performance composites. Also, carbon nanotubes provide the resin important electrical properties, passing from dielectric to semi-conductive class. These effects have also been observed for fiber reinforced composites. Contrarily to some opinions in literature, the results of carbon nanotubes or nanoclays addition on the mechanical characteristics of glass or carbon fiber composites seem to be rather low.

Multifunctional composites and nanocomposites with applications in the aerospace industry

INCAS BULLETIN, 2009

Polymer nanocomposites (PNCs) ,namely, nanoparticles dispersed in a polymer matrix, have garnered academic and industrial interest since 1990. This is due to the very attractive properties of nanostructurated fillers, as carbon nanotubes, laser synthesized nanocarbon and layered silicates; PNCs do not expand the performance space of traditional filled polymers, but introduce new properties, low volume additions (1รท5 %) of nanoparticles such as carbon nanotubes and montmorillonite providing properties and enhancements comparable to those achieved by conventional loadings (15-40%) of traditional fillers [1]. Most important, tough, are value -added such as reduced permeability, flame retardant, increased resistance to oxidation and ablation. Also, the effect of carbon nanotubes on grain boundary sliding in zirconia policrystals as re-reentry shield, or thermal barrier [2]represents a matter of interest. Multifunctional composites are materials with carbon fibre or glass fibre as reinforcing networking in nanoaditivated polymer matrix. In aerospace technique these may be antistatic, antilightning, anti radar protectors, as paints, laminates and as sandwich structure. Though the most important application of nanocomposites is their usability in the engineered structural composites. The work presents a partial synthesis of researches performed in this field by the consortium INCAS, INFLPR, ICECHIM, Ovidius University within the CEEX Programme 2005.

2014

This paper addresses the mechanical behavior of nano reinforcement like carbon nanotubes, graphine sheets, nano particles which are used as a constituent in composite materials. Several authors explored the mechanical properties of nanobased composites. A review of the past research is presented, and several key findings and behavioral characteristics are discussed. An overview covers the prediction of mechanical properties of carbon nanotubes, graphene sheets, nano size particulates and different modeling techniques to represent the nanobased composites, behavior of the nanocomposites under different loading and boundary conditions. Some overall important findings of the studies are that a composite material reinforced with nano substances definitely improves the structural performance of the composite material.
