Manufacturing Processes of Table Tennis Racket Coconut Coir Fiber/Polyester Composite Polymer

Coconut oil waste is considered to be a promising prospect for use and development as natural composite materials. Before use, coconut oil fibers are treated for 24 h in an alkaline treatment of 2% NaOH. In this study, coconut coir fiber was used as a reinforcement for polymer composite materials. The purpose of this study was to make a table tennis racket from a composite polymer material reinforced with coconut fiber. Making of the table tennis racket is by using a press machine. Mixing of coconut fiber and polyester resin is based on mass fraction with a weight ratio of 10:90. Making table tennis racket is by hand layup and compressing mold. Coconut coir fiber is arranged randomly with a layer on a mold in a press machine. The results obtained are a table tennis bat with a composite material that has a thickness of 6 mm and a mass table tennis bat after rubber coating on the bat part is 203 gr.
