MANUFACTURING OF PRE-BOARD WITH ECO-FRIENDLY KENAF-POL YPROPYLENE APPLIED FOR AUTOMOTIVE PARTS

Abstract

Nowadays, resin-polypropylene have been enfolded by automotive industries and suppliers for produce several parts. Regarding to reach zero emissions, kenaf (Hibiscus cannabinus L., Malvaceae) as a natural fiber replace resin. Natural-fiber composites has many different types, however kenaf has been extensively exploited over the past few years. Flow process of kenaf-polypropylene pre-board, starts from mixing kenaf around 40% with polypropylene 60%, fanning become a pre-mat as the first output, entering to major treatment which hot press treatment, until become a pre-board as a final output. Doortrim kenaf-polypropylene highly absorbs CO2, regarding to natural fiber base materials. Doortrim with kenaf-polypropylene as base materials reduce weight approximately 30% from previously resin-polypropylene. Still provide high rigidity even the weight reduce. Kenaf substrate give impact to cost 35% changes from previously using resin. Overall process need 48382.4 kWh/month per cycle for total power consumption.
