COMPOSITE ROD REINFORCED BY A BRAIDED STRUCTURE WITH AXIAL REINFORCEMENT AND PRODUCTION TECHNIQUE THEREOF

摘要

The present invention refers to a composite rod reinforced by a braided textile structure, with axial reinforcement, based on the concept of multifunctional structures, wherein different types of fibre are used in different parts of the rod, according to mechanical and physical requirements. These rods allow a rational distribution of the several types of fibre used, optimizing their use, guarantying the required performance of the rod and contributing to the diminishing of the cost associated to the rod production. The present invention is characterized in that it presents, in its triaxil braiding production technique, integrated in the braiding machine (A), a vat (B) that allows the impregnation of the axial reinforcement fibres in a polymeric matrix, immediately before the braiding process. Therefore, it is guaranteed that the production process occurs in a single step and that the impregnation of the axial reinforced braided structure occurs from the inside out of the structure.
