3D composites are manufactured using 3D forming technology to weave reinforcing fibers into preformed structural shapes with desired configurations. The preforms feature a unique spatial network structure, where the yarns remain continuous and highly aligned throughout the fabric. These yarns are interlaced not only in the planar direction but also along the thickness direction. The preform then serves as the reinforcing structure and is combined with a matrix (such as resin, carbon, silicon carbide, metal, etc.) to form composite components. More Details>
