Abstract: Polypropylene/bamboo fiber (BFP) semi-biocomposites were prepared by melted blend method. Microencapsulated ammonium polyphosphate was added to the BFP semi-biocomposites to improve the flame-retardant properties of the BFP semi-biocomposites. The flame-retardant properties of the BFP semi-biocomposites have been investigated by limited oxygen index, UL-94 test and cone calorimeter test. The results of cone calorimeter show that the peak of heat release rate (pHRR) and total heat release (THR) of the flame-retardant BFP semi-biocomposites decrease substantially compared with that without MCAPP. The pHRR value of flame-retardant BFP semi-biocomposite decreases from 540.0 to 227.5 kW m(-2), and the THR value decreases from 75.3 to 49.2 MJ m(-2). The thermal degradation and gas products of the flame-retardant BFP semi-biocomposites were monitored by thermogravimetric analysis and thermogravimetric analysis-infrared spectrometry.
