Nanocomposite Foams from High-Performance Thermoplastics
Pages 52

Conventional polymeric foams are employed in many application fields such as packaging, buildings industry, transportation (automotive, aeronautics, naval), and human safety because they are lightweight structures that can combine structural properties (stress mitigation, cushion, energy absorption) to functional ones (thermal or electric insulation, acoustic insulation or absorption, weight reduction, comfort management, filtration, thermal stability, fire resistance). The service temperatures in these applications are not much different from room temperature (Gibson and Ashby, 1997) and
