Thermal degradation of coir fiber reinforced low-density polyethylene composites

Thermal degradation of coir fiber reinforced low-density polyethylene composites AbstractIn the present study, the effect of fiber surface treatments (alkali and acrylic acid) on the thermal degradation behavior of coir fiber (CF)-low-density polyethylene (LDPE) composites with or without compatibilizer (maleic anhydride grafted LDPE, MA-g-LDPE) using thermogravimetric and derivative thermogravimetric analyses (TG/DTG) was analyzed and compared with those of untreated fiber composites. The TG/DTG results revealed that the thermal stability of the CF improved after the chemical treatments. However, the composite containing treated fiber showed lower thermal stability and started to degrade at a faster rate above 380°C in comparison to composites containing untreated fiber composites. Furthermore, the addition of MA-g-LDPE led to improvement in the thermal stability of both treated and untreated fiber composites in comparison to the same composite formulation without MA-g-LDPE. The composite containing untreated fiber and MA-g-LDPE demonstrated superior thermal stability among all the formulated composites, indicating strong fiber-matrix adhesion. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Science and Engineering of Composite Materials de Gruyter

Abstract

AbstractIn the present study, the effect of fiber surface treatments (alkali and acrylic acid) on the thermal degradation behavior of coir fiber (CF)-low-density polyethylene (LDPE) composites with or without compatibilizer (maleic anhydride grafted LDPE, MA-g-LDPE) using thermogravimetric and derivative thermogravimetric analyses (TG/DTG) was analyzed and compared with those of untreated fiber composites. The TG/DTG results revealed that the thermal stability of the CF improved after the chemical treatments. However, the composite containing treated fiber showed lower thermal stability and started to degrade at a faster rate above 380°C in comparison to composites containing untreated fiber composites. Furthermore, the addition of MA-g-LDPE led to improvement in the thermal stability of both treated and untreated fiber composites in comparison to the same composite formulation without MA-g-LDPE. The composite containing untreated fiber and MA-g-LDPE demonstrated superior thermal stability among all the formulated composites, indicating strong fiber-matrix adhesion.
