Notes:
Natural fibers are excellent substitute materials for man made fibers in making fiberreinforced composites due to their high specific strength and modulus, low density, low price, easyavailability in some countries, recyclable and degradable properties. They have raised great attentionsamong material scientists and engineers in the past decade. Many researches have been conducted tostudy the mechanical properties, especially interfacial properties of natural fiber reinforcedcomposites. However, the properties, such as mechanical performances, moisture absorptionbehaviors, et. al of natural fibers themselves have been seldom investigated. Knowing the relationshipbetween microstructures and properties of natural fibers are important for understanding the bulkproperties of natural fiber composites and also good instructions for designing bio-mimic materials.In this study, four kinds of natural fibers which were extracted from different plant sources wereinvestigated. The microstructures of these natural fibers were revealed with the aid of opticalmicroscopy. Microstructure models were thereof set up and mechanical properties for therepresentative volume element were assumed. Fiber bundle fracture models together with probabilitystatistics analysis were employed to calculate the mechanical properties of natural fibers. The resultswere compared with the experimental measurements. Different mechanical behaviors of naturalfibers which were functioned differently in the nature were clearly explained by the above studies
