Abstract

The long-term viscoelastic behavior of reinforced all-poly(propylene) composites was studied by flexural creep tests. Both unidirectional and cross-ply laminates were prepared from pure® coextruded tapes by vacuum bag molding in an autoclave. The specimens were subjected to isothermal creep tests at different temperatures ranging from 20 to 80 °C under an applied load. The time-temperature superposition principle was verified for the creep data. An Arrhenius type relationship was found to better describe the shift data obtained from the creep tests. The activation energies relating to the different reinforcement architecture and different relaxation process were calculated.
