MULTIAXIAL THREE-DIMENSIONAL (3-D) CIRCULAR WEAVING AND MULTIAXIAL 3-D CIRCULAR WOVEN PREFORMS FOR COMPOSITE

摘要

This paper reviews multiaxial 3-D circular weaving and preforms for composite applications and presents the development of a new method for producing multiaxial 3-D circular preforms capable of orienting fibers along five axes. The yarn orientation along five axes provides good mechanical properties to the preform. In-plane properties of the multiaxial 3-D circular woven preform may be improved compared to the state of the art 3-D circular woven preforms. Also, the classification scheme of 3-D circular weaving is introduced according to yarn orientations in the structure.
