Textile reinforcement forms (preforms) play an important role in determining the properties of the final composite and product. The preform formation process provides precise control of the fiber architecture and orientation using a suitable textile manufacturing technique. While the techniques employed for preparing glass and carbon preforms are well-known, there is still a gap in understanding on how to prepare natural preforms for composite reinforcements. Multiscale Textile Preforms and Structures for Natural Fiber Composites will bridge this gap by presenting unified knowledge on the relevant preform preparation techniques and resulting fiber architectures. Emphasis is on the structural parameters of each preform and their effect on the final composite properties. This book assembles information and knowledge on natural fiber reinforcement forms, including conventional forms, such as spun yarn, woven, knitted, nonwoven, braided, and comingled. These are illustrated and classified into one-, two-, and three-dimensional reinforcements. This book also includes information on nonconventional preform formation techniques such as unidirectional tapes, pre-impregnated preforms, spread tows, and tailored fiber placement. Covers all relevant textile processing technology for natural fiber preforms Provides academic researchers with a better understanding of recent practices in preparing textile reinforcements for natural fiber composites Helps practitioners determine how to use natural fiber reinforcements in producing new sustainable and innovative composites
