Flame retardant polylactic acid/bamboo flour/aluminium hydroxide(PLA/BF/ATH) composite was prepared by using ATH as flame retardant,and the performance of the composite was tested and characterized.The results show that the mechanical properties of the PLA/BF/ATH composite decrease with the increase of ATH content,but the thermal stability and char residue rate of the composites increase,and ATH shows a certain inhibition on the heat and smoke release of the composites during the combustion.Moreover,the composite has the opt...
