Abstract. This paper presents a study on a new tuneable material for vibration control purposes. The material is formed by a structured fabric wrapped in a deflated bag. The fabric is made of an interwoven mesh of rigid truss-like particles. The vacuum inside the casing produces a jamming effect. Hence, the elasticity and damping of the packaged fabric can be tuned by changing the level of vacuum in the bag. This material can be conveniently employed to develop new vibration control treatments and devices. In this respect, the paper first presents the tests carried out with a six-point bending machine to characterise the static and dynamic stiffness of the material as well as its damping properties. Then it demonstrates an application, where the material is used as a tuneable vibration absorber.
