Abstract

Abstract: Developing the utilization of finger-jointed lumber of small size log from thinning by converting the short and crooked wood into long and straight one is of great importance. The effects of the technical parameters,such as wood moisture content, end pressure, press time, curing time after being.jointed, glue spread and finger profile on the bending strength of fingerjointed lumber were studied and the accelerated ageing properties of the fingerjointed lumber with PRF resin were also determined.

Key words: Wood finger-joint, Thinning, Pinus massoniana Lamb Cunninghamia lanceolata Hook, Bending strength, Performance of Accelerated ageing
