Finite element-boundary elements modelling of acoustic scattering from viscoelastic anechoic structures
… a reflecting aluminium layer, an absorbing butyl rubber layer and a matching layer made of a regular grid of polyurethane cones is finally analysed in several scattering and geometrical configurations. The scattering patterns produced by a plane wave incident on the tile are plotted, …

Functionalized Polyisobutylene: From Synthesis to Properties and Applications
Polyisobutylene (PIB) is a polymer well known for its desirable properties such as high chemical stability, impermeability to gases, and biocompatibility in certain applications. However in some applications it is limited by properties such as high hydrophobicity, lack of chemical functionalities, …

A methodology for developing high damping materials with application to noise reduction of railway track
… types of viscoelastic material, butyl and EPDM rubbers with various amount<br/>of fillers and plasticisers are investigated. The properties of both rubbers have been<br/>measured over the range of temperatures for frequencies 300-3000 Hz. For this a test<br/>rig had to be …
