Acoustic Microscopy Study of Properties and Microstructure of Synthetic and Natural Fiber Composite Materials

摘要

Bio-fiber based composites are gaining acceptance in today's industries. Aimed to replace synthetic fiber-reinforced composite materials, natural fiber composites significantly differ from them in microstructure. Development of new bio-composites shows necessity for effective studies of their mechanical properties. In this paper, properties of bio-composites with different content of wheat straw fillers are analyzed. Microstructure of the composites, its relation to material composition and distribution of the filler phase in the polymer matrix is investigated with acoustic microscopy. The obtained results help to deeper understand structure-property relationship for bio-composite materials and provide feedback for development of new materials with properties satisfactory for industrial needs.
