In this research, requirements of textile composite castings used for immobilizing a damaged limb have been studied as the first step. In the second step, properties of casts used until now was assessed. After that, a fabric composite was made using a new knitted fabric and textured yarn which was not used before. This composite had suitable properties. That of texture was simple and cheap. Properties of materials and the structure used were studied using mechanical tests. Inherent characteristics such as tensile and flexural, and structural properties like compression strength in cylindrical construction of the castings were assessed. Results indicate that the use of textured yarns instead of flat yarns, increases the amount of resin in fabrics resulting an increase in compression strength of composite in cylindrical structure. Furthermore, it decreases tensile modulus of fabrics. Properties of the castings produced were compared with a valid commercial casting named Nemoa. Sample with textured warp and weft, and linear density 1500 den of weft, had the best physical and mechanical properties between produced samples. That of properties was much more like the commercial one.
