NANOENGINEERING OF STRUCTURAL MATERIALS

Abstract

For the past five years, the research involving the fabrication and processing of reinforced polymer nanocomposites has grown exponentially. These new materials are helping in the discovery, development and incorporation of improved organic matrix nanocomposite materials with ease of manufacturing methodologies for several defense and industrial applications. These materials eventually will enable the U.S. to fully utilize nanocomposites in not only reinforcing applications but also in multifunctional applications where sensing and the unique optical, thermal, electrical and magnetic properties of nanoparticles can be combined with mechanical reinforcement to offer the greatest opportunities for significant advances in material design and function. With the loss of the conventional manufacturing jobs in the United States, it is extremely important to maintain our role in basic scientific and engineering research in the nanotechnology manufacturing area, which will help US to maintain its lead in the high tech materials area. Therefore it is important to introduce the basic fundamentals of nanoengineered materials to engineering students at undergraduate level. Presently we are introducing fabrication and processing aspects of the nanocomposites in several courses including Modern Engineering Materials, Introduction to Composite Materials and Engineering manufacturing. This paper will present different nanocomposite methodologies that can be introduced at an undergraduate curriculum without involvement of significant cost. The paper will address three different fabrication processes that has been developed and implemented. These three methods include (a) dispersing carbon nanotubes and or alumina particles using high energy mixing (using ultrasonication, high shear and pulverization), (b) electrospinning technique to manufacture and deposit nanofibers (c) X-Y Computer controlled spray technique to deposit single wall carbon nanotubes on the woven fabric. The fabricated nanocomposite materials are then tested by students in Strength of Materials Laboratory using conventional tensile testing machine. This paper demonstrates limitless bounds of nanomaterials, as well as would eventually help to modify and strengthen the existing engineering curriculums in materials, manufacturing, and mechanical and engineering technology.
