다국어 초록 (Multilingual Abstract)

Wood plastic composites (WPCs) are environmentally friendly because they can be manufactured using waste woody materials and recycled plastics. However, studies performed on using recycled plastics to produce WPCs are still limited. Therefore, in this study, WPCs were prepared by melt-blending followed by compression molding using two kinds of commercially available post-industrial recycled polypropylenes (PPs) and six kinds of coupling agents, and their physical properties were investigated to find a reasonable solution to recycle the recycled PPs. Mechanical properties of the WPCs were investigated by UTM and izod impact tester. Water absorption characteristics of the WPCs were also tested. The WPC with the recycled PP from PP car bumpers and the maleic anhydride PP copolymer with relatively higher maleic anhydride content and higher melting temperature showed most reasonable, commercially applicable physical properties, though its physical properties were slightly lower than those of the WPC with the virgin PP.
