Low density cellular plastics Physical basis of behaviour

Low density cellular plastics Physical basis of behaviour / edited by N.C. Hilyard, A. Cunningham.

Foams are gas filled integral structures in which the gas is finely dispersed throughout acontinuouslyconnected solid phase. The bulk density is usually substantially lower than that of the solid component, and for the foams which form the focus for this book the volume fraction of the gas phase is...
