Abstract:

Wood single fiber is the basic unit of wood. Its properties of physics, anatomy, chemistry were researched more, but the mechanical properties were researched little. In this paper, the importances of mechanical properties for single fiber were indicated, the advance in mechanics properties of single fiber were reviewed, the specimen preparation, clamping, alignment, cross-section area of the cell wall measuring technology for single fiber tensile technique were reviewed detailly, and also the nanoindentation and zero-span tensile techniques, the mechanics properties of single fiber were sumed up, such as the elasticity modulus of longitudinal, tensile strength, creep, fracture, failure, twisting properties. The purpose of this paper was to retrospect the studyments on single fiber mechanical properties, and to bring forward the advices for its continued development.

Key words: wood, mechanics properties, tensile of single fiber, zero-span tensile, nanoindentation
