Mechanical behavior of polymer and ceramic matrix nanocomposites

Recent studies on polymer matrix nanocomposites and nanocrystalline ceramics have shown that tremendous changes in properties can be achieved in these systems compared to analogous materials with micron-scale structures. This paper presents a brief report on the tensile behavior of spherical nanopar...

Description
Summary:Recent studies on polymer matrix nanocomposites and nanocrystalline ceramics have shown that tremendous changes in properties can be achieved in these systems compared to analogous materials with micron-scale structures. This paper presents a brief report on the tensile behavior of spherical nanoparticle alumina-filled polymethylmethacrylate (PMMA) and the hardness and fracture toughness of nanotube-filled nanograined alumina. In each case dramatic enhancements were observed in specific mechanical properties at particular values of the volume fraction, dispersion, and/or surface chemistry of the nanoscale filler. (CSA)
