Dynamic properties of glass-fiber-cored lead-wire reinforced rubber composites

A kind of damping composite made of glass-fiber-cored lead-wire (GF/Pb-wire) and rubber were designed and prepared. The mechanical property and damping property of composites with different structures were studied under compressional loading and shear loading. Results show that the stiffness and the loss factor of all the composites are both higher than those of rubber. The dynamic properties of the composite with vertically laid woven GF/Pb-wires are the highest, and they increase with increasing the volume fraction of GF/Pb-wire. It tells that the improvement of the damping property is because many damping mechanisms work together in the composite, including material damping, interfacial damping and energy dissipation from plastic micro-deformation of Pb.
