Abstract [en]
The objective of this study was to examine oil-retention, swelling, adsorption, static bending properties and tensile strength of lap joints of black pine (Pinus nigra Arn.) wood treated with hot rape oil. Wood specimens were impregnated in a steel vessel using the empty cell process (Lowry method). Rape oil retention of black pine specimens ranged between 122 and 193 kg/m3. Total swelling of specimens was not affected by the impregnation but the rate of swelling was decreased. The impregnated specimens had an adsorption of 21%, while the untreated 75%. The oil heat-treatment process was found to affect the tensile strength of lap joints. The impregnated specimens showed a lower tensile strength of about 10% than the un-treated. The treatment did not affect the static bending strength of black pine wood as deter-mined by the modulus of rupture (MOR) values. However, wood elasticity was affected with impregnated specimens showing higher modulus of elasticity (MOE) values than the untreated.
