摘要: This chapter gives an introduction to the types of vegetable fibers that can be extracted from different parts plants and their sources. These fibers, such as sisal, cotton, jute, bamboo, wood, etc., are popularly known natural (plant) fibers. They biodegradable and, following surface treatments, they develop mechanical properties close those synthetic By virtue this, form important class fibrous reinforcements for fiber reinforced polymer composites. composites, in turn, enable development tribological components having excellent wear, friction lubrication which find numerous applications industry, particularly automotive sector.
