RELATIONSHIP BETWEEN MOISTURE CONTENT AND ULTRASONIC WAVE SPEED DURING KILN DRYING OF BASSWOOD LUMBER

Ultrasonic wave speed was measured in the longitudinal direction of Basswood on the top and bottom surfaces and center of lumbers during kiln drying in 3 Kiln load programs with final dry bulb of 80oC and different relative humidities. On the surfaces, wave speed decreased rapidly with MC declining...
