The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m.sup.2, thereby realizing performance and cost designability of a composite material.

A method and system for forming composite yarns having selected performance characteristics including cut resistance and/or fire/heat resistance. The composite yarn will include a core of one or more filaments and a fiber bundle wrapped about the core and integrated with one or more additional filaments that help bind the fibers about the core. An additional filament or other composite yarn can be plied together therewith to form the finished composite yarn. The core filament(s) will be selected from cut and/or fire/heat resistant materials, while the fibers of the fiber bundle and the additional filament(s) wrapped about the core can be selected from natural or synthetic fibers or filaments having additional desired properties.
