Thin-ply composites are rapidly gaining interest in the composite industry, not only because of the larger design possibilities that they offer, but also because of positive size effects that have been shown to improve performance in various loading condit ...
The aim of this paper is to determine the dielectric characteristics of tropical wood species at microwaves frequency in order to use them as planar antenna substrate. The measurements have been done on dried wood in the frequency range 8.2-12.4 GHz The su ...
Friction welding is a new technology in the course of which wood pieces are subjected to circular or linear movements in a welding machine. The wood in the contact zone is heated and melted. Aiming at a better understanding of the thermal alteration of woo ...
At the Chair of Timber Constructions of the Swiss Federal Institute of Technology in Lausanne (EPFL) tests were carried out to join wooden work pieces by friction welding without any additional welding deposit. It could be determined that this kind of tech ...
Owing to its porous cellular structure and polymeric components, wood can be easily shaped in its transversal direction when it is heated and has sufficient water content. Thanks to this thermohydrous behaviour many manufacturing processes such as densific ...
The reliability of new overhead electric and telecommunication lines depends principally on the quality of their support structures. These structures are generally made of wood, metal or concrete. The complexity of a natural substance such as wood requires ...
Wood properties at macroscopic scale depend on its structure at microscopic scale. Currently, there are few data concerning the microscopic-macroscopic relationship, and this is why here is detailed and developed a method of wood slicing with a thickness o ...
The optimal size and location of bioenergy plants with regards to environmental and economic performance are assessed with a spatially explicit value chain model of the production of synthetic natural gas (SNG) from wood. It consists of several individual ...
Since decades traditional friction welding methods are applied industrially to metal and thermoplastic synthetics. Research showed that for different applications this method is promising for wood too. The process does not necessitate any additional materi ...
Wood, like all polymeric materials, shows viscoelastic behaviour. The time dependent behaviour of wood depends on material anisotropy, temperature, moisture and stresses. To predict the behaviour of wood, numerous mathematical models have been developed la ...
