| Summary: | act:
Wood as a raw material is indispensable in various human activities. Its investigation is
inexhaustible and its responsible valorization, in accordance with current requirements for re-use and
subsequent re-integration, is a priority at national level.
Rotational friction as an alternative method of joining wood elements or wooden structures has
not been addressed in Romania until now, even if it has been under investigation during the past 15
years in the wood field. The paper presents an experimental investigation carried out in order to
analyze the process parameters in case of sessile oak wood (Quercus petraea L.) at the activation of
lignin through rotational friction, with a view to using this method in furniture design as an alternative
for classical (glued) joints.
The results showed that at 1600rpm, sessile oak wood (Quercus petraea L.) registered a more
compact and uniform area of contact than at 1120rpm, on both wood sections. There is a significant
difference between dowels with oblique and linear ribbed joints: the dowels with linear ribs lead to a
more uniform density. The quality of the connection mainly depends on the rotation speed and the
insertion speed.
The overall conclusion of this experimental research is that sessile oak wood (Quercus petraea
L.) can be used for adhesive-free joints for furniture. |
