Thermal conductivity of composites made of wastes of wood and expanded polystyrene

In the present work, a possibility of recycling sediments of woods and polystyrene packing remove from service in view to produce composite materials of wood has been examined. The composite materials consist in that chips or sawdusts of wood sorted in particles of varied dimension and mixed according to a granular composition well defined. The different components are assembled with glue obtained from polystyrene of packing dissolves in a solvent. The thermal conductivity λ determined for this type of composite shows that this one can be used in the realization of the partitions and suspended ceilings.
