Thermal and Biodegradable Issues of Multifunctional Green Composites
This paper deals with multifunctional properties of natural fiber reinforced polymer composites,such as strengthening characteristics,biodegradation behavior and thermal insulating properties.These multifunctional properties are mainly derived from inherent mechanical and chemical characters of natural plant fiber.High performance green composites can be fabricated by using a strong natural fiber such as abaca fiber.The biodegradation speed of natural fiber-reinforced biodegradable composites is faster than that of neat biodegradable resin.Such enhanced biodegradation behavior is attributed to the preferential biodegradation reaction at interfaces between fiber and matrix.In addition,better thermal insulation performance is easily attained by using natural fibers with large lumen,which is the hollow cavity in the natural fiber.Thus the thermal properties of the green composites can be controlled not only by changing the thermal conductivity values of matrix phase but also by changing the internal microstructure of natural fiber.
