Jute fiber reinforced chemically functionalized polypropylene self-compatibilizing composites by Palsule process

摘要

Jute fiber reinforced chemically functionalized polypropylene composites with in situ fiber/matrix interfacial adhesion have been developed by Palsule process. A chemically functionalized maleic anhydride-grafted polypropylene acts as self-compatibilizing matrix eliminating requirements of compatibilizers or any fiber treatment. In situ fiber/matrix interfacial adhesion in the composites, imparted by Palsule process, has been established by field emission scanning electron micrograph and Fourier transform infrared spectroscopy. Mechanical properties of the jute fiber reinforced chemically functionalized polypropylene composites are higher than those of the chemically functionalized polypropylene matrix and increase with increasing amounts of jute fibers in the composite compositions. Measured tensile modulus of jute fiber reinforced chemically functionalized polypropylene composites has been compared with values predicted by rule of mixtures, Hirsch's model, Halpin-Tsai equations, Nielsen equation, and Palsule equation.
