EXPERIMENTAL INVESTIGATIONS ON THE DYNAMIC STRENGTH OF COMPOSITES,
Abstract
A number of experimental techniques for investigating various dynamic properties of composite materials are reviewed. In order to study filler-binder interaction during straining, especially the onset of unbonding, an apparatus was developed for the continuous measurement of the dynamic modulus and damping during constant rate of strain tests. The relation of changes in the dynamic modulus and damping to the development of failure mechanisms is discussed. Various methods of dynamic viscoelastic characterization and strength determination are reviewed. These include stress wave techniques for the investigation of the fracture strength at high loading rates. The various experiments were performed on samples of an unfilled and quartz particle filled epoxy resin. The results of these studies are also reported. (Author)
