Adhesives for the Aerospace Industry
It is anticipated that the design and implementation of advanced nanotechnologies will bring a major revolution to the aerospace industry in the near future. Nano-engineering for the aerospace industry is particularly noteworthy because of the unique benefits which the aerospace industry stands to receive from such advancements. The ability for smaller and lighter solutions which simultaneously maximize crucial characteristics such as strength and heat resistance would be extraordinarily beneficial to aerospace design.
Benefits of Nanotechnology for Aircraft Design
Benefits of Nanotechnology for Aircraft Design include:
- Efficiency - Lighter materials will reduce aircraft weight and in extension cost of use

The remarkable performance properties of nano engineered materials make them particularly appropriate for structural applications in aerospace design. The lightweight aspect of nanomaterials in particular will allow for decreased fuel consumption, an integral variable when it comes to aerospace manufacturing. This consideration, coupled with the high strength, high heat and chemical resistance, and highly flexible properties typical of nano engineered materials, and it is no question that nanotechnology is the future of structural design in aerospace applications for the 21st century.
The study of nanotechnologies incorporation into electronic devices for aerospace applications is an exceptional enterprise already bearing fruit. Electronic devices are a uniquely inviting application of nanotechnology because of the ability nanotechnology offers to increase storage capabilities while decreasing memory mass, an essential variable for efficient memory storage. In addition, the general volatility of the aerospace climate augments the need for highly advanced electronic solutions, capable of uncompromised performance.
Aircraft engine efficiency will inevitably benefit from nano materials whose unique characteristics allow for high temperature exposure. This heat resistant property of nano materials also makes them suitable as thermal barrier coatings in a variety of high end aerospace applications
With an Eye on the Future
With the introduction of nanotechnology and its practical benefits, engineers are paying closer attention to the realistic value in the design and development of what has always been a fantastic science fictional thesis. In its simplest description, a space elevator would involve the development of a fixed cable for the transportation of material and eventually people to outer space. This cable would be held in place on earth, with a counter mass in orbit maintaining necessary tension. The main issue which had always been in the way of serious development was the lack of a suitable cable material that was light weight and able to withstand the enormous stresses such an application would entail. However, in light of the recent advancements of nanotechnology, more specifically, the development of carbon nano tubes, engineers feel that this issue has been resolved.

Master Bond UV22: One Component, UV Curable, Highly Nanosilica Reinforced Epoxy System
Master Bond Polymer System UV22 represents a remarkable technological breakthrough in the utilization of nanotechnology in the formulation of a one component UV curable epoxy for coating, sealing, and encapsulation applications. This nanosilica filled system features superior physical properties, enhanced abrasion resistance, excellent optical clarity along with significantly reduced shrinkage after curing. The performance properties of UV22 surpass those of similar non-reinforced systems by as much as 50-90%. The cycloaliphatic epoxy resin phase offers superior chemical and physical properties together with improved light stability. The silica phase is comprised of surface modified synthetic silicon dioxide nanospheres of very small size (<50nm) and with a very narrow particle size distribution. Despite the remarkably high percentage of nano particles present in the UV22, it still retains high transparency and a desirably low viscosity without sedimentation. This is due to the stability of the agglomerate-free colloidal dispersion of the reinforcing nanosilica particles in the resin phase.
UV22 cures rapidly using light sources emitting a wavelength with 250-365nm with an energy output of as little as 20-40 milliwatts/cm2 with higher output facilitating a faster cure. It can cure within 5-10 seconds with proper UV curing lamps. The shrinkage upon cure is less than 2%. UV22 can be used over the wide temperature range of -60 to 300°F and will cure in thicknesses up to 1/8th of an inch. Additionally, UV22 has excellent electrical insulation properties, and the viscosity of the UV22 system is adjustable to meet specific requirements.
