Abstract

The effect of elevated temperature on the modulus of glass/epoxy composites was studied. Dynamic mechanic analysis (DMA) was carried out to investigate the storage modulus, loss modulus, loss factor and glass transition temperature. Static flexural modulus was also tested by control force mode in DMA. The effect of elevated temperature on the modulus of the composites was evaluated between 30°C and 120°C. A new temperature-dependent model both for the dynamic storage modulus and static flexural modulus was proposed. The model only needed one parameter to fit the experiment data and showed good accordance with experimental results. The physical meaning for the parameter of the model was given.
