EFFECT OF SURFACE TREATMENTS ON MECHANICAL &TRIBOLOGICAL BEHAVIOR OF THE COCONUT SHEATH REINFORCED POLYESTER COMPOSITES
Keywords:
Coconut Sheath, Impact, Wear, Polymer Composites, Chemical TreatmentsAbstract
The results of experimental investigation on impact test and dry sliding wear of unsaturated polyester resin (USP) reinforced with natural woven coconut sheath treated with various chemicals has been given in this article. Among the various treatments, Sodium Hydroxide and Potassium Permanganate treatments enhanced the properties very well. The density and hardness of the coconut sheath reinforced composite was studied and its tribological behavior was tested on pin-on-disc sliding wear tester. For different sliding velocity and load, mass loss was determined. The chemically treated fiber reinforcement showed greater increase in mechanical properties of the composite in comparison to untreated fiber reinforced composite. Furthermore, the investigation showed that inter laminar adhesion was increased due to the chemical treatments on fiber.
