Abstract

This study was conducted to investigate the effects of applying methods and
amount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy and
mechanical properties of wood flour/polypropylene composites. The results
showed that addition of fire retardant improved the mechanical properties such as
tensile and flexural strengths and fire retardancy of composites. But by increasing
of fire retardant impact strength decreased. The scanning electron microscopy
observation on the fracture surface of the composites indicated that fire retardant
had a uniform dispersion in the wood flour/PP composites. The observations
showed that saturation of wood flour with fire retardant had a positive effect on
mechanical properties and fire retardancy.
