Polymeric materials are constantly exposed to aggressive environments, negatively impacting their mechanical and chemical properties. In salt, acid, or alkaline solutions, polymer degrade due surface flaws, microcracks, other irregularities. For the first time, this study considers behaviour of coconut powder/coir-reinforced synthetic LDPE hybrid composite immersed in an (acidic) medium for 15, 30 45 days. The structural, mechanical, frictional developed coir/coconut husk powder/LDPE...
