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.

控制随机纤维材料强度的参数

许多日常使用的材料都是纤维状的，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，例如网络密度、交联密度、纤维弯曲度和纤维间交联强度。考虑了细胞和纤维类型的无热网络。我们得出结论，对于广泛的网络参数以及所考虑的两种类型的网络，网络强度与交联数密度和交联强度呈线性关系。网络强度与纤维材料特性和纤维弯曲度无关。此信息可用于设计具有指定强度的纤维网络，并且通常用于了解纤维材料的机械性能。
