许多日常使用的材料都是纤维性的，它们的强度在大多数应用中都很重要。在这项工作中，我们研究了随机纤维网络的强度对结构参数的依赖性，如网络密度，交联密度，纤维弯曲度，和纤维间交联的强度。被认为是细胞和纤维型的无热网络。我们的结论是，网络强度与交联数密度和交联强度的线性尺度为一个广泛的网络参数，并考虑这两种类型的网络。网络强度独立于纤维材料性质和纤维弯曲度。这些信息可用于设计具有特定强度的纤维网络，通常还可用于了解纤维材料的机械性能。(C)2019爱思唯尔有限公司版权所有。
Many materials of everyday use are fibrous and their strength is important in most applications. In this work we study the dependence of the strength of random fiber networks on structural parameters such as the network density, cross-link density, fiber tortuosity, and the strength of the inter-fiber cross-links. Athermal networks of cellular and fibrous type are considered. We conclude that the network strength scales linearly with the cross-link number density and with the cross-link strength for a broad range of network parameters, and for both types of networks considered. Network strength is independent of fiber material properties and of fiber tortuosity. This information can be used to design fiber networks for specified strength and, generally, to understand the mechanical behavior of fibrous materials. (C) 2019 Elsevier Ltd. All rights reserved.
