Multiaxis three‐dimensional circular woven preforms – “radial crossing weaving” and “radial in–out weaving”: preliminary investigation of feasibility of weaving and methods

Abstract

The aim of the study is to develop new preform structures and processes to use in the technical textile and composite industries. Multiaxis and orthogonal three‐dimensional (3D) circular woven preforms and weaving methods have been developed. The multiaxis structure has five yarn sets as (±)bias, axial, circumferential, and radial yarns whereas the orthogonal structure has three yarn sets, axial, circumferential, and radial yarns. Two weaving methods, radial crossing and radial in–out weaving were introduced to form the structures. An experimental rig was constructed to evaluate the methods. Basic process and structure parameters have been identified. The preliminary studies showed that the multiaxis 3D circular woven preforms and methods seemed feasible.
