EFFECTS ON MECHANICAL PROPERTIES OF NEW HYBRID FIBER REINFORCED POLYPROPYLENE COMPOSITES

EFFECTS ON MECHANICAL PROPERTIES OF NEW HYBRID FIBER REINFORCED POLYPROPYLENE COMPOSITES Parallel to the development of novel fiber with high stiffness and strength, composite materials were produced. The first reason to employ composite materials is to take use of fiber's excellent mechanical properties. The dispersion of reinforcements either particles or fibers can increase matrix qualities such as ceramic toughness, polymer conductivity, metal high-temperature mechanical capabilities etc. resulting in novel applications. The Natural fibers are a good alternative to most popular composites because of their inexpensive cost, ease of manufacture, and great mechanical and tribological characteristics. Composites can be used to create a wide range of materials. The physical and mechanical qualities of traditional polypropylene materials will be improved by using these natural fibers in the right way. The present invention disclosed herein is Effects on Mechanical Properties of New Hybrid Fiber Reinforced Polypropylene Composites comprising of Jute and Luffa Aegyptiaca Fibers reinforced with polypropylene to produce novel hybrid fiber, focuses on the use of natural fibers in polypropylene composites. The Polypropylene is used to reinforce the novel hybrid fiber made from natural fibers developed by combining Jute and Luffa Aegyptiaca. Different weight fractions of hybrid fiber developed by combining Jute and Luffa Aegyptiaca are reinforced with polypropylene and the effects of the mechanical properties are noted in the disclosure. The mechanical properties show that the Jute and Luffa Aegyptiaca Fiber reinforced with polypropylene produces a strong hybrid new composite material. The tensile strength of Jute and Luffa Aegyptiaca fiber reinforced composites increases at 15% weight fraction before decreasing. At 15% weight fraction of Jute and Luffa Aegyptiaca fiber reinforced composites, the maximum tensile strength is 28.78 MPa and the tensile modulus is 668 MPa. The tensile strength of Jute and Luffa Aegyptiaca fiber reinforced composites at 20% weight fraction is 23.87 MPa, while the tensile modulus is 776 MPa. The flexural strength and modulus of pure polypropylene are calculated to be 115 MPa and 4.295 GPa respectively. At 20% and 15% weight fractions of Jute and Luffa Aegyptiaca fiber reinforced composites, the flexural strength and flexural Modulus are 200 MPa and 9.259 GPa respectively. The impact strength of pure polypropylene is 5.5 J/m, and the impa
