Abstract
Understanding viscoelastic properties of composite materials is essential for the design and analysis of composite structures. Specially, the loss factor and Young's modulus must be known to develop finite element codes for a composite structure with several damping materials. In this study, an advanced technique for obtaining accurate loss factor and Young's modulus of a composite structure is introduced based on ASTM(American Society for Testing and Materials) and a curve fitting method. The loss factor and young's modulus of a composite structure are measured for different temperatures by performing the test in a vibration measurement room where temperature can control from 5 to 45 Celsius.
