Paper Title
Effect of Diammonium Phosphate Modification on The Chemical and Physical Properties of Ramie Fibers Reinforced Pla Composites
Abstract
Ramie fibers reinforced PLA composites were manufactured by the help of hot compression machine. Ramie
fibers were first treated with sodium hydroxide and later soaking in diammonium phosphate for further treatment. The
efficiency of diammonium phosphate on interfacial adhesion has been evaluated by FTIR, TGA, and SEM. The FTIR results
indicated that DAP-treatment had done well on the ramie fibers. The thermal degradation of treated ramie fibers PLA
composites were significantly reduced as compared to theuntreated sample. The mechanical properties of treated ramie fibers
PLA composites were superior to the untreated ramie fibers composite. The SEM graphs showed that DAP has distributed
well in the fibers, and therefore, treated fibers become smoother and cleaner.
