Abstract

Carbon fiber Triaxial Woven Fabric (TWF) reinforces flexible matrix material silicon. As a new type of high-performance composites, they have both flexibility and rigidity and can be used as the reflector surface of the high-precision deployable antenna. In order to obtain the mechanical properties of TWF composites, the micro-mechanics method of composites was used. The unit cell entity finite element model was established, and then the homogenization analysis of the model was applied, obtaining the equivalent homogeneous material properties. In order to meet the high-performance requirements of antenna reflectors, the influence of key material parameters-carbon fiber types and fiber volume fractions on material bending properties were analyzed; The establishment of meso-model and the analysis of mechanical properties of low-porosity TWF composites that might be applied at higher frequencies were carried out, showing that the anisotropy was more obvious than the TWF composites.
