| Abstract | ||
| Mechanical properties of (LDPE-463): Helianthus annuus shell particles composite were assessed with respect to the effect of filler content Helianthus annuus shell range from (5%,10%,15%,20%,25% 50%) by weight in the composite. The volume off Helianthus shell particles was (<425) micrometer. The mechanical properties of loaded film have been evaluating through several parameters concerning the elastic deformation based on measuring the load – elongation characteristics and through several parameters like Elongation, Tensile at break and Tensile at yield. The obtained results show that Helianthus annuus shell particles increase the free volume among polymeric chains indicating a poor ability against applied stress. The behavior of (stress-strain) curve is analyzed of cold drawing model. No experimental difficulties appeared for all mixing ratio under 50% with no separation in phase which makes the sample processing is possible. The Elongation is decrease with increasing filler concentration where a rapid decrease is obtained due to high concentration of filler. Both tensile at yield and break are also decrease indicating a composite of less elasticity. The filler ratio 5% is found to be best due to it's Elongation while 40% is consider as the saturation value. | ||
