The utilization of a Brabender Mixer Machine, the fibers and polylactic acid (PLA) particles were thoroughly and uniformly combined. Different weight fractions were designed for the kenaf fibers, PLA, and treated and untreated EFB fibers. With a 1:1 ration of two fibers, the percentage of fiber to PLA is 50:50. The ASTM 638 and 790 standards were followed in the design of the mold manufacturing and the desired composite thickness. A hot-pressing technique was utilized to create the composite materials. Then, until the pressure obtained 1000 psi, the mold was crushed through a hydraulic jack. The mold was heated for five minutes at a temperature of 160 °C on both the upper and lower heaters. To avoid any shrinkage during the composite extraction process, the mold was allowed to cool for approximately five minutes without being opened. Table .
