Abstract
Kenaf bast fiber was used to prepare the composite composed of kenaf fiber and linear low density polyethylene (LLDPE). The thermal stabilities of kenaf fiber and kenaf fiber/LLDPE composite were investigated using thermogra vimetric analysis (TGA) in nitrogen and air atmosphere. The result obtained in inert condition showed that kenaf fiber has lower thermal stability than pure LLDPE and kenaf fiber/LLDPE composite. On the other hand, thermooxidative de gradation of them revealed that kenaf fiber/LLDPE composite has higher thermal stability than pure LLDPE beyond 400°C, indicating kenaf fiber has antioxidant effect for LLDPE.
