摘要：参照国家标准要求,测试麻栎和栓皮栎木材的主要力学性能。结果表明:两种栎木的顺纹抗压强度、抗弯弹性模量、抗弯强度等级均为高,冲击韧性等级为甚高;硬度等级均为很硬,且端面>弦面>径面;树种间差异为麻栎木材的顺纹抗剪强度等级为高,栓皮栎木材为中。综合评价,两种栎木的力学性能均属于中高等材级别,麻栎木材的各项力学性能指标更高。
The main mechanical properties of Sawtooth Oak(Quercus acutissima)and Oriental Oak(Q.variabilis)were tested according to Chinese national standards.The test results showed that the compressive strength parallel to grain,the modulus of elasticity and the bending strength level of the two oak wood samples were all at a high level,the toughness of the samples reached a very high level,and the hardness grades of the samples were both very high.The hardness of the samples in the three grain dimensions was ranked:transverse>tangential>radical.The shearing strength parallel to grain of the Sawtooth Oak wood samples was high,while that of the Oriental Oak wood samples was medium.In summary,the mechanical properties of the both Oak wood species are at the medium to the advanced level.Sawtooth Oak wood is superior to Oriental Oak wood in mechanical properties.
