Abstract

The mechanical properties of walnuts shells composites were studied. The range of added walnuts shells has the values (0%, 2.5%, 5%, 10%, 15%, 20%, and 25%) of polyethylene weight and, the best fibers ratio was 10 % and 15 %. Obvious improvement in the mechanical parameters was recorded when adding walnuts shells with 10% weight ratio. The properties (LDPE /walnuts shells ) composites were analyzed as a function of the powder amount. All prepared composites showed improved powder dispersion in the low density polyethylene matrix. All composites displayed lower elongation of break compared to pure LDPE. The best added ratio was 15% of LDPE weight which gave Proportional limits 140 N.
