APP was used as flame retardant for blending with bamboo flour and polylactic acid, the flame retardant polylactic acid / bamboo flour composite was prepared by moulding technology, and the performance of the composites was tested and characterized. The results show that the mechanical properties of composite decrease with the increase of APP content, but the extent is not obvious, and the thermal stability and mass retention rate of the composites increase. Moreover, the heat release of the composites during the combustion is inhibited obviously by APP, nearly half of the heat release rate of...
