ABSTRACT:
A load bearing structural support for machinery which provides a mechanism or dissipating both mechanical and vibrational energy comprises a high damping flexible reinforcement of fiber preform infiltrated with a viscoelastic material which has a high elongation to failure property and provides a significant damping ability. In one embodiment, an I-Beam is formed by a pair of L-shapes and a T-shape. The two L-shapes are placed back to back, with the T-shape placed therebetween forming an I-beam. At least one flexible reinforcement is then positioned between the vertical segments of the T-shape and the two L-shapes to isolate the T-shape. The T-shape is actually "floating" between the L-shapes. In another embodiment, the flexible reinforcement is suspended between at least a pair of spaced anchors with a vertical support of the same flexible reinforcement attached to or integral with the suspended flexible reinforcement portion and its free end anchored to a stable base.
