Mechanical Dissipation in Random Fiberglass Networks under Small Strains

Résumé

Glass wool is used extensively for thermal and acoustic insulation in buildings, appliances, automotive and aerospace applications. In this work we study the response of fiberglass networks crosslinked using polymeric binders to small amplitude oscillatory excitation in the low acoustic frequency range. Two types of binders are used, with low and high damping, and a range of fiber densities and binder volume fractions are considered. We report the scaling of storage and loss moduli of the network with these parameters. Further, we evaluate the loss factor and find that it is independent of the fiber mass density but is power law related to the binder volume fraction. We develop a model that provides a mechanistic basis for the experimental results reported and may guide material design.
