摘要
从木材构造、化学组分和水分等因素对木材动态黏弹性的影响及其机理进行了综合评述。从木材构造方面,阐述了树种、应力木,以及木材的心边材、幼龄材与成熟材、纹理方向、早晚材和微纤丝角等对木材动态黏弹性的影响规律;针对木材化学组分,重点归纳了弹性纤维、黏弹性基体以及抽提物对动态黏弹性的影响机制;总结了木材动态黏弹的水分依存性。最后,对木材动态黏弹性的进一步研究提出了建议。
Researches on wood dynamic viscoelastic properties are focused in recent years. Dynamic viscoelastic properties are helpful for investigating wood rheology and provide scientific instructions for wood industry. This paper reviewed the effects mechanism of anatomy structure,chemical composition and moisture on wood dynamic viscoelastic properties.For the anatomy structure,the emphases were concerning the species,stress wood,heart wood and sap wood,juvenile wood and mature wood,grain direction and earlywood and latewood as well as microfibril angle. For the chemical composition,the emphases were concerning elastic fiber,viscoelastic matrix and extractives. The dependence of moisture to dynamical viscoelastic properties were summarized in this paper. The suggestions for further study to wood dynamic viscoelastic properties were put forward.
