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.
