Abstract

Bamboo fiber-reinforced composites, noted for their light weight, have seen application in automotive interior components. However, their flammability presents significant risks to vehicular safety. In this study, melamine polyphosphate (MPP) was used to flame-retardant modify bamboo flour (BF) reinforced polypropylene (PP)/ poly (lactic acid) (PLA) composites. The results showed that MPP are contribute to enhancing the thermal stability and improving the flame retardancy of composites. Notably, the peak of heat release rate (629.66 kW/m²) of BF reinforced PP/PLA composites containing 5% MPP was reduced by 35.23% compared to unmodified composites (972.09 kW/m²). Besides, compared with other composites, composites containing 5% MPP constituted the lowest fire hazard. In terms of mechanics, it is notable that MPP could significantly enhance the flexural and tensile moduli of the composites. Meanwhile, composites containing 5% MPP yielded the optimal flexural strength (41.52 MPa) and tensile strength (53.79 MPa). These results suggest that MPP is a viable candidate for flame-retardant modification of BF reinforced PP/PLA composites, offering potential for use in automotive interior components.
