Weaving thickness parameters of '8' shape 3D woven enhancing fabric

摘要

Purpose - The purpose of this paper is to deduce the thickness property of three-dimensional (3D)rncomposite produced by 3D woven enhancing fabric based on an academic model.rnDesign/methodology/approach - Thickness of 3D composite is determined by the importantrnweaving parameter - the length of binder yarn. According to the shape of pile formed by binder yarn,rncurve function of pile is supposed. A rapier loom is modified for the 3D woven enhancing fabrics, andrnthe composite is produced based on the fabric. The thickness of composite is produced and the theoriesrnresults are validated.rnFindings - The result of the analysis shows that the curve of pile formed by binder yarn can bernexpressed as sin function approximately, and there is linear relation between the thickness ofrncomposite and the length of pile of binder yarn.rnResearch limitations/implications - The results cannot be provided to study the relationship ofrnthickness based on different technology of composite.rnOriginality/value - The paper provides an academic method of calculating the thickness ofrncomposite and the relationship between the thickness of composite and the length of binder yam. Thernmethod can reduce the testing time.
