The work described in this paper relates to the evaluation of some of the parameters determining the impact response properties of flexible beams made from a foam-filled fluid which is a blend of elastomeric capsules or beads in a matrix fluid. When these composites are impacted, the pressure that develops inside the beam plays a role in the shock absorbing properties of the composite. The beam composition could vary as to the volume of beads, the type of beads, the viscosity and the volume of the matrix fluid. For this work the same type of beads and fluid are used for all the tests. However, different levels of constraint are applied on the flexible and expandable material used for the skin of the beams. This is done by increasing the number of layers of skin material. In this way a higher pressure is allowed to develop inside the beam at different increments of constraint levels. It is shown that as the level of constraint is increased, so does the pressure that develops inside the beam, and so do the shock absorption characteristics of the composite.
