Natural  fiber(NF)  reinforced  poly(lactic  acid)(PLA)  composites  have  received  a  lot  of  research  attention because of their excellent biodegradablity. However with
the addition of the flame retardancy, the properties of the  composites such as the mechanical properties are greatly  decreased.  Poly(butylenes  adipate-co-terephthalate)  (PBAT)  is  an  aliphatic-aromatic  copolyester,  which  is fully  biodegradable.  In  the  view  of  its  high  toughness  and  biodegradability,  PBAT  is  considered  as  a  good candidate for the toughening of PLA matrix. In  the  present  study ,  jute  /poly(lactic acid)/poly(butylenes  adipate-co-terephthalate) (jute/PLA/PBAT)  composites  were  prepared  by  twin-screw  extruder  and  two-roll  mill.  Ammonium  polyphosphate  was used as flame retardancy.  The effect  of  PBAT  on  the  properties  such  as  tensile,  flexural  and  impact  strength  of  the  composites  were  studied.
Flammability  and  melt  stability  of  the  composites  were  thoroughly  evaluated  by  means  of  limiting  oxygen index(LOI)  measurement,  60  second  vertical  burn  test,
and thermogravimetric(TG)  analysis. The results showed that  with  the  addition  of  PBAT,  the  composites  can  get comparatively  better  mechanical  properties  and
flammability properties.
