Development and evaluation of physical properties of PLA matrix composites reinforced with SCB/CF fiber

Researchers are increasingly focusing on natural, biodegradable materials because of environmental concerns. Although natural fibers give less strength than synthetic fibers, but they still contain some specific properties. In this paper, we studied the fire and water resistance, density, and swelling behavior of sugarcane bagasse fiber and chicken feather fiber composites using polylactic acid (E-3051D) as a matrix for different weighing fractions of fiber viz. 03%, 06%, 09%, (03 + 05)%, (06 + 05)%, (09 + 05)% and for 3 mm thickness. The 300 mm x 300 mm panels were made using the compression molding. According to ASTM standards, an investigation was carried out on several physical characteristics, including density, moisture content, water absorption, linear swelling, and a flammability test. It was observed that 3% sugarcane bagasse and 5% chicken feather fiber are better for various applications, as further increments will affect the mechanical properties. It is a combination of natural fibers and biodegradable matrix material, which makes it ecofriendly with various applications such as in automobile interiors, packaging materials, wall panels, window and door frames, and roof sheets, but limited use in bathroom and kitchen areas.
