Three-dimensional model for analysis of stiffness and hygroexpansion properties of fiber composite materials

Stålne, Kristian LU and Gustafsson, Per-Johan LU (2002) In Journal of Engineering Mechanics 128(6). p.654-662
Abstract
A three-dimensional model for stiffness and hygroexpansion of fiber and particle composite materials is presented. The model is divided into two steps, first a homogenization of a single fiber with a coating representing the matrix material, then a network mechanics modeling of the assembly of coated fibers that constitutes the composite material. The network modeling is made by a fiber orientation integration including a linear and an exponential interpolation between the extreme case of homogenous strain and the extreme case of homogenous stress. A comparison between the modeled prediction and measurement data is made for stiffness, Poissons ratio, and hygroexpansion. The matrix material is assumed to have isotropic properties and the...
