Shear loaded friction-welded crosswise arranged timber boards

Till Vallée, Yves Weinand, Benjamin Hahn

Friction welding of wood is a bonding technology that can be used for joining timber elements, and in which the adhesive is formed from thermally modified cell wall material within the substrate during the welding process. In this paper, this principle is ...

Influence of surface shapes on the mechanical behaviour of friction welded wood bonds

Bernhard Stamm, Yves Weinand, Benjamin Hahn

Friction welding of wood is a fast and adhesive-free bonding technology for the production of timber joints with good mechanical characteristics making this type of connection interesting for applications in timber construction. However, the moisture stabi ...

Linear friction welding of spruce boards: experimental investigations on scale effects due to humidity evaporation

Bernhard Stamm, Yves Weinand, Benjamin Hahn

Recent investigations on friction welded wood-to-wood connections have shown interesting capacities of these adhesive free joints for further development towards constructional elements. This paper addresses challenges and technical requirements for the en ...

Upscaling of Friction Welding of Wood for structural Applications

Benjamin Hahn

The present work deals with the large-scale application of the friction welding bonding technology on timber. The investigations that are described in the following were carried out on a prototype of a welding machine that was previously developed for the ...

Experimental Investigations and Probabilistic Strength Prediction of welded Double Lap Joints composed of Timber

Bernhard Stamm, Till Vallée, Yves Weinand, Benjamin Hahn

Wood-to-wood bonds obtained by means of friction welding are a relatively new type of connections holding high potential to compete with existing structural adhesives, since a load bearing bond is formed almost instantaneously. This paper addresses the que ...

Experimental investigations on welded double lap joints composed of timber

Bernhard Stamm, Till Vallée, Yves Weinand, Benjamin Hahn

Fabrication of wood-to-wood connections by means of friction welding is an relatively new process holding high potential for development. To connect wooden pieces by means of friction welding, they are initially pressed against each other. The rapid moveme ...

Numerical modelling and strength prediction of welded double lap joints made of timber

Bernhard Stamm, Till Vallée, Yves Weinand, Benjamin Hahn

Welding of wood is a relatively new method of joining load bearing elements, which holds the potential to compete with structural adhesion, since it allows for an almost instantaneous bond. First experimental and numerical investigations showed that failur ...
