摘要：

A study of the tension and compression behavior of glass-fiber reinforced polyester composite material under sustained loads and elevated temperature is presented. Time-dependent thermal deformation and failure stresses were measured at three different temperatures (T = 25, 50, and 80 degrees C). Using curve-fitting equations a simple empirical model was developed to predict the time-to-failure. The model takes into account superposition of time-temperature effects. Creep curves predicted by this model are similar to those reported in literature. (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
