THE INFLUENCE OF MOISTURE CONTENT ON THICKNESS SWELLING AND MODULUS OF ELASTICITY IN ORIENTED STRAND BOARD BENDING
Popis výsledku v původním jazyce
Th e main theme of this study was an analysis of the moisture content (MC), thickness swelling (TS) and its relationship to modulus of elasticity in bending (MOE), For this case samples from OSB/3 Superfinish (Czech producer Kronospan) were used. All analyses were performed with EN 310 standard-sized specimens. Th e specimens were exposed to 15, 35, 50, 65, 85 and 100% relative humidity (RH) and 20°C for absorption and desorption. Analysis results clearly show that MOE decreases with an increase of board moisture content. For an MC change from 5 to 22 %, an average MOE loss of 44 % in the parallel direction and 39 % in the perpendicular direction was measured. Th is MOE loss corresponded to a 21% thickness swelling. Predictive equations expressing theMOE bending as a function of MC and TS were determined.
