Experimental investigation on physical, mechanical, and thermal properties of jute and hemp fibers reinforced hybrid polylactic acid composites

Abstract

Nowadays researchers seeking attention on plant‐based natural fibers as reinforcement with the biodegradable matrix‐like polylactic acid (PLA) to solve the environmental issues. In this research work, jute and hemp fibers are reinforced with PLA matrix with the weight fraction of 50:50 and the composites are fabricated by using compression molding technique. The properties such as hardness, tensile strength, flexural strength, impact strength and inter‐laminar shear strength (ILSS), and water absorption characteristics are evaluated. The characterization of these composites are examined by using thermo‐gravimetry analysis, differential thermal analysis, differential thermo‐gravimetric, and scanning electron microscopy analysis. Experimental results show that the jute/hemp/PLA hybrid composites exhibit better tensile strength (69 MPa), flexural strength (145.40 MPa), impact strength (6.37 J), and ILSS (2.98 MPa) than other combinations. From the thermal analysis it is found that the decomposition and weight loss occurring started around 250°C and ended by 350°C. From the experimental analysis it is concluded that the hybrid composites performed well, indicating that they have a lot of potential for use as a green substitute material for synthetic or single plant fiber reinforced composites.

Experimental Studies on Mechanical and Thermal Properties of Polyester Hybrid Composites Reinforced with Sansevieria Trifasciata Fibers

“…Natural bers are environmentally friendly bers derived from natural sources because natural ber reinforced composites (NFRCs) are completely biodegradable in soil. In addition to that, NFRC has merits such as recyclability, low density, and cheap cost over man-made bers [3]. NFRC is frequently used in automobile and structural parts due to its lower weight, biodegradable, and higher speci c strength [4][5][6][7].…”

Influence of Tamarindus indica seed nano‐powder on properties of Luffa cylindrica (L.) fruit waste fiber reinforced polymer composites

“…The reinforcement of plant‐based fibers in polymer matrix enhances the hardness of the composites. [ 29 ] ASTM D2240 standard is used for the preparation of the specimen to determine the hardness (Shore‐D) of fabricated composite samples. Shore‐D durometer was used to find out the mean hardness values of prepared LCF fiber/epoxy composite samples.…”

Thermal characterization and hygrothermal aging of lignocellulosic Agave Cantala fiber reinforced polylactide composites

“…PLA‐based plant fibers reinforced composites are heat sensitive and thermally degradable, resulting significant influence in the thermal stability of the composites. [ 37 ] The thermal characterization was done with the use of TGA technique; that finds use in the analysis of the thermal stability of the composites by monitoring mass during heating. TGA provide details of second‐order phase transitions and information relating to chemical phenomena like chemisorption.…”
