In this paper, the effectiveness of reinforcement in direction 3 has been estimated by investigating the mechanical characteristics of two types of three-dimensional reinforced materials differing with respect to the arrangement of the reinforcement and the fiber content in each direction.Abstract:
The effectiveness of reinforcement in direction 3 has been estimated by investigating the mechanical characteristics of two types of three-dimensionally reinforced materials differing with respect to the arrangement of the reinforcement and the fiber content in each direction. The superior transverse stiffness, shear strength, and transverse tensile strength of three-dimensionally reinforced composites based on a system of three mutually orthogonal fibers, as compared with laminated materials, is demonstrated. The theoretical values of the elastic constants, calculated from the relations of [5], are compared with the experimental data.read more
