Abstract

U ovom diplomskom radu provesti će se istraživanje o utjecaju različitih karakteristika hrastovine (Quercus robur L.) na dielektričnu konstantu u električnom polju visoke frekvencije u laboratorijskim uvjetima. Karakteristike hrastovine koje će biti varirane su: tekstura drva, volumna masa drva, sadržaj vode i vlaga ravnoteže. Priprema uzoraka za mjerenje dielektrične konstante će biti obavljena u klima komori pri više različitih temperatura i vlaga ravnoteže. Navedeno istraživanje će u proizvodnim uvjetima poslužiti kao osnova za mjerenje zagrijavanja drvnog materijala koje je neophodno provesti pri savijanju masivnog drva.

Abstract (english)

In this thesis, research will be conducted on the influence of different characteristics of oak wood (Quercus robur L.) on the dielectric constant in a high-frequency electric field in laboratory conditions. The characteristics of oak wood that will be varied are wood texture, wood volume, moisture content and equilibrium moisture content. The preparation of samples for measuring the dielectric constant will be done in a climate chamber at several different temperatures and equilibrium moisture contents. In industrial conditions, the mentioned research will serve as a basis for measuring the heating of wood material, which must be carried out when bending solid wood.
