Validation study on the theory of composites by using three

Abstract RoM, as a reinforcement theory of composite materials, has been widely used. With the advent of new materials and molding processes, this theory is constantly being refined and validated. In this paper, four high-tech fibers as continuous reinforcing materials and carbon nanotubes as non-continuous reinforcing materials were evaluated, and two ideal composite samples were designed using three-dimensional printing technology. The reliability of RoM was verified by tensile testing. Also, a fiber tensile fixture was designed. The fiber bundle strength was inversely proportional to the length and the number of roots of fiber. In verifying the RoM, three-dimensional printing was employed, showing the diversity and complexity of the testing samples
