In this article, the tear damage of triaxial woven fabric (TWF) and its reinforced rubber composites (TWFR) are investigated. Numerical simulation method for the yarn level is developed to predict the tear properties of samples with pre-cut in different directions, and the experiment method is used to verify the results of finite element analysis. It is analyzed that the changing law of tear load and the characteristics of tear failure during tear process. The results indicate that the load-displacement curve can be divided into low modulus region, high modulus region and shock region, which are related to initial stage, pre-cut opening stage and tear opening expansion stage the tear process of TWF and TWFR. When the pre-cut is parallel to the yarn, TWF and TWFR have higher tear load and larger tear starting position.
