Measurement of surface roughness of Salix psammophila scrimber using stylus profilometer and extended depth-of-field 3D microscope
摘要
Abstract
Salix psammophila scrimber resulted from processing rapidly sandy shrubs into fiber reinforced composites,has a large cross section with outstanding strength.As a kind of homogeneous material,the density and the size of scrimber is controllable,which can replace the solid wood to a certain extent.It is extremely important to have an overall evaluation of surface roughness of wood-based materials due to the unique and complicated surface texture.In this study,the characteristics and principle of a new method(extended depth-of-field 3D microscope)for the mea-surement of wood surface roughness was investigated,and the traditional 2D tactile stylus profilometer method was al-so used for comparison.In addition,the effects of relative humidity on the measurement of surface roughness were in-vestigated.The results indicated that the extended depth-of-field 3D microscope is an available and efficient method to measure the surface roughness of wood-based materials.Moreover,it was found that the high relative humidity expo-sure adversely influenced the surface roughness of samples and the change of humidity had a greater impact on the uni-formity of surface texture of the SP scrimber.It turned out that it is urgently necessary to consider the impact of rela-tive humidity on the measurement process.关键词
