METHOD FOR MANUFACTURING NATURAL FIBER-REINFORCED PLASTIC FOR VEHICLE INTERIOR MATERIAL AND NATURAL FIBER-REINFORCED PLASTIC FOR VEHICLE INTERIOR MATERIAL MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing a natural fiber-reinforced plastic for a vehicle interior material and the natural fiber-reinforced plastic for a vehicle interior material manufactured thereby and, more specifically, to a method for manufacturing a natural fiber-reinforced plastic for a vehicle interior material with an easy extrusion process and enhanced physical properties, by firstly mixing 5-35 wt% of a natural fiber with an average length of 5 mm or greater and 1-10 wt% of a coupling agent and then injecting 55-80 wt% of a plastic resin into a main injection hole of a twin-screw extruder, and injecting a mixture of the natural fiber and the coupling agent into a side injection hole of the twin-screw extruder so as to perform extrusion, and to the natural fiber-reinforced plastic for a vehicle interior material manufactured thereby.;COPYRIGHT KIPO 2016
