Effect of Compatibilization on Wear and Surface Energy Properties of Carbon Fiber Reinforced High Density Polyethylene Composites

Abstract
In this work, three different copolymers in the market are used as compatibilizer in carbon fiber (CF) reinforced high density polyethylene (PE) composites. The used compatibilizers are a random terpolymer of ethylene, acrylic ester and maleic anhydride (LOT-MA) and a random copolymer of ethylene polyethylene grafted maleic anhydride (PE-g-MA) and glycidyl methacrylate (LOT-GMA). Three different concentrations of compatibilizer (1.5, 3 and 6 wt%.) were used. The type and amount of compatibilizers on the wear and surface energy properties of composites are investigated. From wear test results, it is found that composites compatibilized with LOT-MA have the best wear resistance, in parallel with the results of the Shore-D hardness test. However, the increase in concentration of the compatibilizers was found to have a negative effect on wear resistance of the composites. Regardless of the compatibilizers type, the surface energy of all composites reduced by adding compatibilizers. Surface energy of the composites containing LOT-MA have lowest surface energy from the others. With the increasing concentration of each compatibilizer, the surface energies of composites are reduced. İndex Term- Carbon fibre, compatibilizer, high density polyethylene, wear.
