Abstract Although fibrous suspensions are finding increasing use in many applications, holistic studies investigating their material properties are essentially non-existent due to a lack of simple and reliable measurement techniques. To address this, geotechnical techniques have been considered for the characterisation of an extruded suspension of poplar fibres. Use of such characterization techniques was thought suitable since the extruded fibres share many physical similarities with fibrous peats, and since both materials are primarily derived from plants. In the present study, oedometer and direct shear tests were employed to evaluate the compressibility, permeability and friction properties of poplar fibres. Triplicates of each test were carried out for two differently prepared poplar fibres at several different initial water contents. All measurements were found to be in good agreement with the values typical of fibrous peats, justifying direct cross-over of geotechnical techniques as an alternative method for characterising and modelling fibrous suspensions in manufacturing applications.

天然纤维的材料特性：可压缩性、渗透性和摩擦力

摘要 尽管纤维悬浮液在许多应用中得到越来越多的使用，但由于缺乏简单可靠的测量技术，调查其材料特性的整体研究基本上不存在。为了解决这个问题，已经考虑使用岩土技术来表征杨树纤维的挤出悬浮液。使用此类表征技术被认为是合适的，因为挤出的纤维与纤维泥炭具有许多物理相似性，并且这两种材料主要来自植物。在本研究中，采用固结仪和直剪试验来评估杨树纤维的可压缩性、渗透性和摩擦性能。对两种不同制备的杨树纤维在几种不同的初始含水量下进行三次测试。
