摘要：
Utilizing industrially discarded bio-waste as a bio-reinforcement for polymer composite is one way to find alternate solution for harmful, conventional man-made vitreous fibers. In this work, one such agro waste, tamarind fruit fiber is tested comprehensively for its potentiality as a reinforcement in unsaturated polyester matrix to optimize the mechanical properties. 40 wt% fiber content provides optimum properties, while further addition of fiber reduces the strength due to ineffective bonding between the fiber and the matrix. This is revealed in the microscopic images of the fractured tensile specimens. The experimental results are verified and correlated with the Hirsch's and Series models and found that Hirsch's model agrees well with the experimental results. Thermal stability and aquatic properties are ascertained by the degradation temperature and the water absorption characteristics in fresh and sea water. The diffusion coefficient is found to follow pseudo-fickian behavior. Comprehensive analysis of this material confirms its applicability for light weight automotive and marine applications.
