ABSTRACT
Fiber architecture is the arrangement of fibers in a Polymer Matrix Composites (PMC) and has a strong influence on its properties, performance, and failure behavior. It also plays a key role in fiber impregnation, matrix infiltration, formability, and so on, that determine the quality of the manufactured composite part. Linear fiber architecture is created when fibers are oriented all in the same direction. The linear fiber architecture is utilized in making laminates of multiple laminas or layers of unidirectional continuous fibers. Two-dimensional fiber architecture is available in three different forms: woven fabrics, knitted fabrics, and braided fabrics. Knitted fabrics are produced by interlooping one or more yarns on a knitting machine, similar to that used for making garments. Noncrimp fabrics (NCFs) have multiple layers of straight fibers, but the angular orientations of the fibers can vary from layer to layer. Stitching has several advantages over weaving or knitting. It can be used with both dry fabrics and resin-impregnated fabrics.
