Overview

Three Dimensional Weaving is a nascent technology which has  triggered research interests around the world. The technology has the potential to finely balance the in-plane and out-of plane properties in composites. This state-of-the-art book focuses on three emerging 3D weaving technologies viz., Orthogonal weaving, Angle interlock weaving and Dual Plane shedding based 3D weaving. It provides focused knowledge about these technologies  and  has a pragmatic approach to developing customized  3D weaving machines. Fundamental approach to  understanding weave design basics,  thereupon practical weaving , addressing quality aspects, arriving at testing  approaches are all detailed  in the book. The applications for these technologies are both in strategic (space, aerospace, defense) as well as societal (medical, automobile) sectors. The book has  six chapters, wherein the  first three  chapters are  devoted to Orthogonal and angle interlock  weaving and their quality control aspects. Approach to weaving preforms of complex geometries such as T-stiffeners, tapers, Origami-based structures  are  also discussed The fourth and fifth chapter are entirely devoted to machinery development for Dual plane shedding based 3D weaving often termed as ‘True 3D weaving’. The chapters discuss detailed machine design of the sub-elements such as let-off, shedding, picking, beat-up and take-up. The reader is taken through a prototype development of a 3D weaving machine by way of concept, illustrations, practical development and weaving of samples.  The sixth chapter summarises the editor’s views about the technology. This volume will be beneficial to scientists and researchers in both academia and the industry.

Author Information

Dr. B. S. Sugun is currently a Senior Principal Scientist at the Center for Societal Missions and Special Technologies (CSMST), CSIR – National Aerospace Laboratories at Bengaluru. He has an interdisciplinary background with a Bachelor’s & Master’s degree in Textiles Technology coupled with a Ph.D. in Mechanical Engineering. He has been working in the area of polymer matrix composites research for the past two decades. Some of his early works were on  Low velocity impact behavior of Polymer Matrix  composites, resin transfer molding, fiber metal laminates & glass-knit composites. In the last decade, he has focused on the technology of 3D weaving. His research work revolves around evolving novel concepts for indigenous 3D weaving machinery, Near-net preforming approaches and developing creative weave designs for engineering the preforms for use in composites. His recent endeavors comprises of  developing a  prototype  machine  for dual plane sheddingbased 3D weaving wherein basic concepts of the technology have been practically realised,  development of an automated  customised take-up-at-will 24 shaft dobby loom, utilizing pleat weaving concept for weaving T-stiffeners, development of hybrid carbon-Kevlar preform for fuselage wing joint of Micro air vehicle and weaving complex geometrical shapes using 3D noobed and angle interlock weave architectures ex., gas turbine engine nozzle flap. He was a Raman research fellow at the University of Manchester, UK in 2015, where he worked on addressing fiber lay-up schemes for rotational symmetric components using robotics approach and also worked towards the development of  specific Profiles  for applications in composites using  three dimensional braiding. He has several peer reviewed publications, conference papers & has delivered several invited talks. With participation from a private industry within the country, he is currently developing a commercially viable, production version multi weft insertion 3D weaving loom for use in textile industries. He is currently associated with the Quality Assurance and Airworthiness  activities  of NAL in addition to his research works at CSMST.
