竹木复合层积材的力学性能及耐老化性能
Mechanical and aging resistance properties of bamboo-wood composite LVL
摘要
Abstract
Bamboo-wood composite laminated veneer lumbers (LVL) with 3 densities were prepared in this study. The material chosen were bamboo strips near bamboo green and birch veneers. Mechanical properties of the boards and the influence of accelerated aging were studied. The results showed that in the density range from 0.9 to 1. lg/cm3, the values of MOR were above 220 MPa. The values of MOE were above 20 GPa. The values of compressive strength parallel to the grain were above 150 MPa. And the values of tensile strength parallel to the grain were above 200 MPa. All the strengths increased with the increase of board density. Accelerated aging test showed that the retention rate of board mechanical properties was more than 75% , showing a strong anti-aging ability.关键词
