Evaluation of Damping for Glass Fiber Reinforced Composite Materials

Abstract:

A structural composite is a material system consisting of two or more phases on macroscopic scale whose mechanical performance and properties are designed to be superior to those of the constituent materials acting independently. One of the phases is stiffer and stronger and is called reinforcement and less stiff and weaker phase is known as matrix. This paper presents an experimental analysis of the dynamic characteristics of the unidirectional fiber composite as functions of fiber orientation, temperature, frequency and ramp rate. Dynamic characteristics of glass fiber composite are measured using dynamic machine analyzer (Triton 2000) in three point flexure bending. Micromechanical finite element model is modeled in NISA FEM software and damping of composite material is predicted and results are compared with experimental result.
