Mechanical properties of pineapple leaf fibre reinforced polypropylene composites

Abstract

Pineapple leaf fibre, which is rich in cellulose, relative inexpensive and abundantly available has the potential for polymer-reinforced composite. The present study investigates the tensile and flexural behaviours of pineapple leaf fibre-polypropylene composites as a function of volume fraction. The tensile modulus and tensile strength of the composites were found to be increasing with fibre content in accordance with the rule of mixtures. The tensile modulus and tensile strength with a volume fraction 10.8% are 687.02 and 37.28 MPa, respectively. The flexural modulus gives higher value at 2.7% volume fraction. The flexural strength of the composites containing 5.4% volume fraction was found to be higher than that of pure polypropylene resin by 5.1%. Scanning electron microscopic studies were carried out to understand the fibre-matrix adhesion and fibre breakage.

Utilization of Pineapple Waste: A Review

“…A yield of 2.1g fibger/100 g pineapple pulp waste has been reported (Sreenath et al, 1996). Furthermore, pineapple leaf fibers are investigated in making fiber-reinforced polymeric composites because of high cellulosic content, abundance and inexpensiveness (Devi et al, 1997;Luo and Netravalli, 1999;Arib et al, 2006). They investigated the tensile, flexural, and impact behavior of pineapple leaf fiber-reinforced polyster composites as a function of fiber loading, fiber length, and fiber surface modification.…”

Evaluation of Mechanical Properties of E-Glass and Coconut Fiber Reinforced with Polyester and Epoxy Resin Matrices

“…Tensile strength of oriented discontinuous fiber composites was evaluated by single fiber pull out showed the fiber/matrix adhesion was good due to the natural waxy surface [16]. Tensile and flexural strength of pineapple leaf fiber reinforced polypropylene composites as a function of volume fraction were found to be increasing with fiber content, in accordance with the rule of mixtures [17]. Straw reinforced polyester composites with volume fraction of 40% resulted in high tensile strength 104 MPa [18].…”

Natural Pineapple Leaf Fibre Extraction On Josapine And Morris

“…From the research found, there are fibre in the pineapple leaf. Before this, the fibre from plant leaf are from banana [4]. Environmental awareness, new laws, and legislation are forcing industries to find new materials which are environmental friendly.…”
