Three-dimensional woven fabric is one of the textile composite materials that have attracted much attention in recent years. Since the technologies and methods for producing such fabric are quite diversified and they have solved the problems often seen in two-layer composite materials such as fabric layers are easily separated due to poor bonding capacity, and moreover,they have the advantages of high specific strength, high specific modulus, excellent resistance to impact and strong designability, three-dimensional woven fabric have been widely used in the fields of aviation & aerospace, military, automobile, building, medical, etc.
