Structural Characterization and Mechanical Behaviour of LDPE Structural Foams. A Comparison with Conventional Foams

摘要: Structural foams are composed of two solid layers enclosing a foamed core. The application sandwich structural has rapidly increased in the lastdecade. Injection moulding is currently used to produce these foams, being not common conventional ofsimilardensities and chemical compositions similar process. In this paper an alternative route been used. This method allowsfabricating conventionalfoams with same composition density than so comparisons between properties both kinds materials can be made proper way, i.e. avoiding effects different and/or densities. mechanical tension, compression bending have characterized for based on low polyethylene. results showed that structure structuralfoams improves 50% behaviour bending, however no improvements or tension found.
