Title: The prediction of long-term creep data of fibrous polymer composites based on short term experiments
Biography
Biography: Urs Meier
Abstract
After a short review of the historical development of the time-temperature superposition principle, its application for the extrapolation of creep modulus curves will be discussed with the help of two examples. Conditions for the applicability of the principle for fibrous polymer composites will be pointed out. The normalization of the measured data will be revealed. The construction of the master creep modulus curve will be demonstrated in detail. The extrapolated values resulting from the superposition of short-term creep data of an unsaturated polyester-glass fiber composite are going to be compared with the results of long-term creep experiments. Based on this outcome, it can be concluded that the timeâ€temperature superposition principle is for the prediction of longâ€term creep behavior a suitable tool for R&Dâ€laboratories to get a good impression about the tendency of the longâ€term creep behavior of fibrous composites.
