The damping capacity of the spray-formed MMCs also depends on the volume fraction of the reinforcement, as illustrated in Figure 19(a) for a spray-formed 6061 Al/graphite composite. It should also be noted that, since the elastic modulus of graphite is much lower than that of the matrix 6061 Al, the elastic modulus of spray-formed MMCs decreases as the damping capacity increases (Figure 19(b)).
Dynamic behaviour of rubber and rubberlike materialsThe attention is focussed on new types of Silicon rubber. These types show stable damping properties over a wide temperature range.

The Difference Between Elastic Materials and Viscoelastic Feb 03, 2015 · Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Synthetic polymers, wood, and human tissue, as well as metals at high temperature, display significant viscoelastic effects. In some applications, even a small viscoelastic response can be significant.
An annular chamber (8) is formed between a pipeline section (1) and a housing (5, 6) surrounding same. This annular chamber is in communication, via openings (10, 11) in the wall of the pipeline section (1), with the interior (12) of the latter. An air-filled hose ring (16) is arranged in the annular chamber (8). The device damps the pressure surges occurring in domestic installations on
Vibration Damping Characteristics of Hybrid Polymer the damping characteristics of Hybrid polymer composite, which can be used in many applications, and in engineering structures. Glass and carbon fibre reinforced with epoxy matrix hybrid composite have to be prepare by hand-lay-up vibration damping are mainly 1.metals, 2.polymers and rubber because of their viscoelastic character.
Vibration damping properties of materials selection. However, the hybrid structure properties depend on the properties of the constituent materials as well as on the interfacial properties. In the present study, the damping properties of laminated structures consisting of steel, rubber or epoxy adhesive and glass fibre reinforced epoxy composite were studied.

What Material Is Best for Damping? - sorbothaneFeb 04, 2015 · What Characteristics Make a Material Best for Damping? Evaluate a damping material by determining how efficiently it performs with the types of energy present in your application, such as vibration, impact, or noise. Determine if its damping properties work simultaneously across multiple types of energy or across a wide range of frequencies.DampingCharacteristicsofMetalRubberinthePipeline istics of a ship pipeline. eir results showed that rubber damping has an obvious damping performance compared with a rigid connection.
