Characterization and Factors Effecting Fiber Properties

A single agro-based fiber is a three dimensional, biopolymer composite composed mainly of cellulose, hemicelluloses, and lignin with minor amounts of free sugars, starch, protein, extractives, and inorganics. The performance of a given fiber used in a given application depends on several factors including chemical composition, physical properties, the interaction of a fiber within the composite matrix, and how that fiber or fiber/matrix performs under a given set of environmental conditions. In order to expand the use of agro-fibers for composites, it is essential that information is available on fiber characteristics and the factors which effect performance of that fiber. In order to do this, it is necessary to develop a detailed data base of chemical and physical properties of the vast variety of natural fibers that are potentially available in the world. It is also necessary to understand the factors which effect the performance of a given fiber in a given application. This chapter will deal with the chemical and physical properties of agro-fibers and factors which effect fiber properties.
