In this article, simple viscoelastic and empirical models are presented to predict and analyze the flexural creep behavior of all-poly(propylene) (all-PP) composites. Results of the successful application of these models to the actual creep behavior of unidirectional (1,113) and cross-ply (Cl?) all-PP composites tested by short-term flexural creep measurements over a temperature range of 20-80 degrees C are presented. Analysis of the momentary creep behavior of all-PP composites with different tape lay-ups are made to understand their deformation mechanism. Further to the main theme of the article, an interesting discrepancy while predicting the long-term creep behavior of these composites based on the time-temperature superposition (TTS) principle and Findley power law model is visualized which has also been illustrated here.
