Study the effect of the adding of Ash of Palm Fronds on the Mechanical Properties for High Density Polyethylene (HDPE).

Abstract

The mechanical properties of (HDPE - ash of palm fronds) composites were studied. The range of added powder of ash of palm fronds has the values (0%, 1%, 2%, 3%, 4%, 5%, 7.5% and 10%) of polyethylene weight and the best ratio was (10 %). The mechanical properties of (HDPE / ash of palm fronds) composites were analyzed as a function of the added powder amount. All prepared composites showed improved powder dispersion in the high density polyethylene matrix. More composites displayed lower elongation of break compared to pure HDPE. The results lead to that the strength at breaks will be affected little till the percentage (3%) is (6.8 Mpa), and increased after that with increasing the percentages, also indicate a lowered in young's modules (Young modulus) which at the percentage (3%). The highest value of the proportional limit was when the proportion of the added polymer (2%) is (431.2 N) while the less proportion limit of which (372 N) at the percentage is (4%).
