Abstract

     The Effect of Ash of Palm Fronds powder on the Mechanical properties of low density polyethylene (LDPE) was studied as a function of the percentages of Ash of Palm Fronds (1%,2%,3%,4%,5%,7.5%,10%). At particular size (75 µm) were investigated through several variables such as stress at yield, young's modules, strength, elongation and proportional limit . The obtained results showed that the added Ash of Palm Fronds reduces the spaces between the polymer chains, which reflects the high ability of the polymer against the applied stress. The increase of added Ash of palm will give further property that increase the hardness of the prepared specimens. The results have lead to  the strength at break which will be affected by little of the percentage (1%), and lowered after that with increasing the percentage also indicate an lowered in young's modules at the percentage (3%). The maximum value of the proportional limit was (192.5 N) for percentage (1%), while the minimum value of the proportional limit was (130.2 N)  for percentage (7.5%).
