A BULK MODULUS MODEL FOR AN EPOXY + GLASS FIBER COMPOSITE AS A FUNCTION OF PRESSURE AND TEMPERATURE

摘要

Temperature and pressure-dependent volumetric changes of the 8552/S2 epoxy + glass fiber composite were investigated by a Pressure-Volume-Temperature (PVT) technique. The Hartmann equation of state was used to develop a model for prediction of the bulk modulus as a function of both pressure and temperature. This model describes the experimental data very well over a wide range of temperatures and pressures.
