The aim of this study is to investigate the thermal and flammability properties of poly(lactic acid) (PLA) biocomposites reinforced with calcium hypophosphite (CHP) and magnesium hypophosphite (MHP) impregnated jute fiber (JE). For this purpose,biocomposites were produced by adding the jute fibers (JEs), which are treated separately with 5% and 10% CHP and MHP solutions and dried, to the PLA at a constant rate (20% wt) by melt blending method. Thermal properties of the PLA biocomposites produced were evaluated by thermogravimetic analysis (TGA), also their flammability properties were investigated by using limit oxygen index (LOI), vertical (UL-94V) and horizontal burning (UL-94HB) tests. As a result of the TGA tests, it was determined that the addition of JEs impregnated with CHP and MHP, the thermal stability and char residue amount of PLA biocomposites increased, and consequently the flame retardancy of the composites were also improved. From the LOI test results, it was observed that the LOI values of PLA biocomposites increased as the percentage of hypophosphites in the JE treatment solution increased. UL-94V and UL-94HB tests indicate that PLA biocomposite reinforced with JEs treated with 10% wt CHP has the highest flame retardancy performance.
