Abstract

High density polyethylene (HDPE) composite reinforced with 20wt% orange peels ash particles(OPAp) was prepared by compression moulding. Thermogravimetric analysis(DTA/TGA) was conducted on the HDPE/OPAp composite to clarify the effect of OPAp on the thermal decomposition behavior of the resultant composite. The values of the activation energy forthermal decomposition reflected the improvement of the thermal stability of the HDPE/OPAp composite. This study has established that the orange peels ash particles are beneficial to act as thermal decomposition resistant and reinforcing particles in the HDPE matrix composite.
