Study of the mechanical properties of high density polyethylene (HDPE)‎ composites with alum powder

الملخص EN

The mechanical properties of (HDPE - Alum powder) composites were studied.

The range of added powder of Alum has the values (0%, 2.5%, 5%, 10%, 15%, 20%,25% and 30%) of polyethylene weight and, the best ratios were 10 % and 15 %.

The obvious improvement in the mechanical parameters was recorded when adding Alum powder with 10% weight ratio.

The properties of (HDPE / Alum powder ) composites were analyzed as a function of the added powder amount.

All prepared composites showed improved powder dispersion in the high density polyethylene matrix.

All composites displayed lower elongation of break compared to pure HDPE.

The highest value of the proportional limit was when the proportion of the added polymer (5%) is (367.5 N) as it will be at this homogeneity rate strong between powder Alum with chains of polymer while the less proportion limit of which (234 N) at the percentage is (25%).
