This study effect of carbon ash content on the thermal stability and combustion behavior of waste wood particle / recycled polypropylene composites was investigated using TGA, DTG, LOI and cone calorimeter. The TGA shows that, as carbon ash content increases, the thermal stability of composites increases, while the residual weight significantly increases, with the residual weight rate of waste wood particle / recycled polypropylene composites increases from 13.97% to 41.02% at 800 ℃ According to cone calorimeter results, in the 50 kW/M2 thermal flow, when carbon ash adding to 70%, peak heat release rate and total heat release quantity, decreases by 68% and 52%, respectively. The LOI of waste wood particle / recycled polypropylene composites improves by about 34%, Conforming UL-94 flammability standard, V-0 rating. The residual weight rate increases by 202.8%, which the significant role of carbon ash in flame retardant.
