Mechanical Behaviour of H2so4 Treated Tire Rubber- HDPE Composites

Recycled tire particles are used to make a HDPE- recycled rubber composite. rubber particles either treated or untreated are used . The chemical treatment for rubber particles by H2SO4 is essential to increase the adhesion between the polymer and rubber particles. Mechanical properties, Bending strength, toughness, Young’s modulus and impact strength, are studied to evaluate the effect of rubber particle weight percentage and also the effect of rubber treatment on the properties of the composite. SEM is used to justify the results achieved from the mechanical testing. Keywords— Recycled tire rubber; impact strength-HDPE composite;H2SO4 treatment; SEM-Bending test.
