| Abstract: | It is a very important and complex task to estimate the thermo-elastic properties of a textile structural composite. In this paper, the finite element method (FEM) was used for the prediction of the orthotropic thermo-elastic properties of a composite reinforced by glass fiber knitted fabric. In order to define the final 3-D configuration of the loop reinforcing structure, the interactions between the adjacent loops, the large displacement and the contact elements without friction were considered. The values predicted were compared with the experimental results. |
