Geometric modeling of 3D woven preforms in composite T-joints (2017)
Journal Article
Yan, S., Zeng, X., Brown, L., & Long, A. (in press). Geometric modeling of 3D woven preforms in composite T-joints. Textile Research Journal, doi:10.1177/0040517517712098. ISSN 0040-5175

A common method to fabricate net-shaped three-dimensional (3D) woven preforms for composite T-joints is to weave flat 3D preforms via a standard weaving machine with variation in binder yarn path and then separate the preform in the form of a bifurca... Read More
