Abstract
Drilling features of particleboard made of selected fruit trees prunings. In this work the selected mechanical and physical properties of wood based panels originated from fruits trees pruning, namely: plum trees, apple trees, as well as drilling ability, were analyzed. As reference material were used panels based on particles produced from pine wood in industrial conditions. All three kinds of samples were subjected to tests in order to asses modulus of elasticity (MOE), modulus of rupture. (MOR), and volumetric density. Moreover, drilling process of above mentioned materials regards to axial force and torque was analyzed. It can be concluded that lowervolumetric (bulk) density (more vulnerable material to densification) resulted in the higher MOE or MOR value for reference panels. Besides, such machinability indicator as axial force turned out the highest for apple wood what is in coincidence with high volumetric density affecting drilling process similar as unit density. However, the differences between these three kinds of samples due to torque values are not so obvious. It is worth to enhance that panels made of fruit trees prunings proved significantly high value of MOE. Even the lowest value observed for apple panels (2432N/mm2) exceed the minimal standard requirements (according to PN-EN312:2011) for over 52%. From friendly environmental approach these results are very promising because of the fact that fruit trees prunings are very often assumed as waste material.
