提出了一种各向同性近平面随机纤维网络中纤维间预期接触度的模型。本文考虑了二维纤维网络中纤维接触的统计特性，导出了二维结构叠加后的接触面积的表达式。这些表达式允许仅根据网络孔隙率来表示分数接触面积。对于薄网络，接触面积分数可以用网络孔隙率和网络的预期覆盖率来表示。理论允许的一个接触的预期面积的确定，因此预期的接触每纤维的数量也。良好的协议之间的表达式推导出的分数接触面积和文献中的数据。(C)2004 Kluwer Academic Publishers.
A model is presented for the expected degree of contact between fibres in isotropic near-planar random fibre networks. The statistics of fibre contact in two-dimensional fibre networks are considered and the expressions derived are developed to allow the fractional contact area in structures formed by the superposition of two-dimensional structures to be derived. These expressions allow the fractional contact area to be expressed in terms of the network porosity only. For thin networks, the fractional contact area may be expressed in terms of network porosity and the expected coverage of the network. Theory permitting the determination of the expected area of one contact and hence the expected number of contacts per fibre is presented also. Good agreement is found between the expressions derived for the fractional contact area and data from the literature. (C) 2004 Kluwer Academic Publishers.
