Characterization, design, specific properties and applications of thermoset composites are reported. These composites are presently in high demand because they can be shaped into many-sided segments and structures, and can have a great variety of densities and special physical and mechanical properties. The research reported includes: Energy absorption of fiber reinforced composites; automotive crashworthiness; lignocellulosic composites; hybrid bast fiber reinforced composites; nano-carbon/polymer composites; electromagnetic shielding; structural mechanical applications; electromagnetic field emission applications, conductive composites; epoxy composites for structural purposes; tribological performance of polymeric composites.
