Static and dynamic mechanical behavior of doum palm (Hyphaene thebaica) nut reinforced HDPE composites


 The quest to discover more and enhance the qualities of agro-residue for use as natural reinforcement polymers continues attract attention researchers because environmental friendliness. Hyphaene thebaica also known doum palm is a fruit tree native Nile in Egypt found abundance many parts Africa. Doum contains probably hardest toughest nut. nuts (DPN) are most under-used hard-nut despite their nature. This study presents potential nut particles (DPNp) high density polyethylene (HDPE). Properties DPN such density, hardness weight loss due heating were determined. HDPE/DPNp composites produced by reinforcing HDPE with 30, 35, 40 45% DPNp two different sizes. particle sizes 600 μm 710 led classifying X-composite Y-composite respectively. static dynamic mechanical properties determined compared those pure HDPE. Results showed that can be formed into light attractive components. Loading HPDE significantly improve tensile strength, hardness, stiffness resistance impact failure 50%, 200%, 800% 1500% had better properties. ability maintain load bearing capacity under conditions was superior HDPE.
