| Abstract: | Study on anatomy properties, physical and mechanical properties, slicing, peeling and other processing and utilization adaptabilities of different aged timbers of Schima superba collected in Zhejiang province showed that it had a turning point at the age of 20-25 of physical and mechanical properties of the timbers such as density, air shrinkage, bending strength, compressive strength, shearing strength, hardness and modulus of elasticity. Its main physical properties and mechanical strength reached intermediate level of domestic hardwood materials. Its peeled plywood bonding strength was even beyond the national standards for technical requirements. The study resulted that S. superba timbers were suitable for producing plywood, slicing effects of panel overlaid and properties after overlaying showed good comprehensive performance. |
