Abstract

The use of fiberplastic composite (FPC) for exterior purposes raises issues related to durability FPC against weather influences. Discoloration is one problem that often occurs in the products that are used for the purpose of exterior use. Discoloration of the product exposed to weather effects will reduce the aesthetic appearance of a product.The main objective of this research was to evaluate discoloration of FPC after exposed to weather for 6 months.In this study, there were 6 treatments consisting of two factors, namely the ratio of FPC materials (corrugated paper fibers and polyethylene) which consists of 3 levels ie 50:50, 60:40 and 70:30 and the additional factor of maleic anhydride (MAH), which consists of two levels, namely 5% and 7%.The results showed that after exposure to the weather for 6 months, the discoloration on the FPC are initially black to white dull. At the70:30 ratio with the addition of 7% MAH the discoloration are not too drastic than in the comparison of 50:50 and 60:40. Discoloration on the surface of the FPC caused by photodegradation by UV light. Degradation mainly occurred in the lignin component and cause discoloration. The addition of MAH cannot reduce discoloration of the FPC after exposure for 6 months.Keywords : fiber plastic composite, discoloration, weathering test.

Abstract

The use of plastic fiber composite (FPC) for exterior purposes as one alternative to solid wood has a variety of power requirement one of which is resistant to termites. This study aimed to test the durability of fiber composite plastic derived from recycled corrugated old paper fibers and polypropylene (PP) with the addition of maleic andhirida (MAH) as compabilitizer and benzoyl peroxide (BPO) to termite attack. This research used Completely Randomized Design (CRD) factorial, there are two factors: comparison of corrugated old paper fibers and polypropylene (PP), which consists of 50:50, 60:40 and 70:30 and additive factors maleit anhirida (MAH) 1% and 2% and the results were compared with JIS A 5905-2003 S20 hardboard and JIS A 5908-2003 particleboards type 13 for physical properties and SNI 01 7202-2006 to test the grave yard test termites. The results showed after trials testing the grave for 100 days, the physical properties of the fiber composite plastic does not entirely meet the testing standards JIS A 5905-2003 S20 hardboard and JIS A 5908-2003 particleboards type 13. To test resistance to termite attack, some fiber plastic composite that meets the ISO standard FPC 50:50 01 7202-2006 1% MAH, 1% MAH 60:40, 60:40 and 70:30 2% MAH while the remaining 2% are outside the standard. The Patterns of termite attack on FPC 50:50 70:30 2% and 1% MAH MAH resembles a circular pattern.Keywords : corrugated old paper fiber, polypropilene, fiber plastic composite, durability against termite attack.
