Abstract Melamine polyphosphate (MPP) and aluminum hypophosphite (AHP) flame retardants were introduced into high density fiberboard (HDF) to prepare MPP/AHP-HDF composites by hot pressing technology of wood-based panels. The effects of flame retardants on the properties of composites were investigated by bending strength, impact strength, limiting oxygen index and cone calorimetry test. The results showed that the flexural strength and impact strength of the composites decreased obviously with increasing the flame retardant content. According to SEM characterization, it can be found that the poor compatibility between the flame retardant and matrix was observed. Furthermore, the stress wasn't able to transfer effectively within the material, leading to the inferior mechanical properties. The flame retardancy of the composites was investigated by limiting oxygen index (LOI), and the flame retardant mechanism was also analyzed. The results showed that with the increase of flame retardant, the LOI values of the composites increased gradually with increasing the flame retardant contents. The LOI value of the composites reached 40% when the content of flame retardant reached 15%, meanwhile, the peak value of heat release and total heat release had a downward tendency. This was because MPP and AHP could promote effectively the char formation during the combustion process. Moreover, MPP could produce a lot of non-combustible gases which diluted the amount concentration of combustible gases. All these effects could improve the flame retardant properties of the composites.
