This book contains chapters on nanocomposites for engineering hard materials for high performance aircraft, rocket and automobile use, using laser pulses to form metal coatings on glass and quartz, and also tungsten carbide-cobalt nanoparticles using high voltage discharges. A major section of this book is largely devoted to chapters outlining and applying analytic methods needed for studies of nanocomposites. As such, this book will serve as good resource for such analytic methods.
Polymer nanocomposites are commonly defined as the combination of a
polymer matrix and additives that have at least one dimension in the nanometer
range. The additives can be one-dimensional (examples include nanotubes and
fibres), two-dimensional (which include layered minerals like clay), or three-
dimensional (including spherical particles). Over the past decade, polymer
nanocomposites have attracted considerable interests in both academia and
industry, owing to their outstanding mechanical properties like elastic stiffness
and strength with only a small amount of the nanoadditives.
This configuration enables the rubber to be loaded in both shear and compression with the majority of engine rotational flexibility being carried out in shear. Vertical deflection due to body pitch when accelerating or braking is absorbed mostly in compression. Vertical elastic stiffness may be increased without greatly effecting engine roll flexibility by having metal spacer interleafs bonded into the rubber.

Wave propagation in solids has been widely studied and principal advances in this field have been achieved not only for the improvements of calculus methods, but also for the high progresses attained in the description of new types of materials. This book presents innovative and original research studies describing some enhancement in both directions.
