Abstract: The dynamic mechanical properties of Chinese fir oriented laminated stick lumber (OLSL) and its constitution unit—Chinese fir wood stick were examined by dynamic mechanical analysis. The results showed that the storage modulus (E′) of Chinese fir wood stick and OLSL rapidly decreased with experimental temperatures increasing, but their loss tangent delta and loss modulus (E″) rapidly increased; the storage modulus(E′)of wood sick was reduce after it making into Chinese fir OLSL; and their glass transition temperature were 95℃ and 80℃, respectively.
