Detail The properties degradation of exposed GFRP roof (article of AIP Conference 2018 Proceedings Vol.1931 Iss.1 030063 ) Bibliografi Author: Zainudin, Mohammad ; Diharjo, Kuncoro ; Kaavessina, Mujtahid ; Setyanto, Djoko Bahasa: (EN )     Penerbit: AIP Publishing     Tahun Terbit: 2018     Jenis: Article - diterbitkan dalam Proceeding Internasional Fulltext: 1.5024122.pdf (3.99MB; 0 download) [Informasi yang berkaitan dengan koleksi ini di internet] Abstract There is much consideration of roof selection as a protector of a building against the outside weather, such as lightweight, strong stiff, corrosion resistant and guarantee for the availability of products. Based on these considerations, glass fiber reinforced polymer (GFRP) roof is a roof which can fulfill the requirement. The objective of this research is to investigate the degradation of physical and mechanical properties of GFRP roof exposed in outside weather. This GFRP roof composite was produced using a sheet molding compound (SMC) supplied by PT Intec Persada, Tangerang, Indonesia. There are two kinds GFRP roofs evaluated in this research that are GFRP roof exposed within 7 years and new GFRP roof that has not been exposed. The GFRP roofs were cut manually for preparing the specimens for hardness test, tensile test, SEM and FTIR test. The results show that the GFRP roof exposed within 7 years had the degradation of properties compared to the new GFRP roof. The exposed GFRP roof had lower strength and hardness compared to the new GFRP roof. The SEM observation indicates that exposed GFRP roof had the debonding of fiber on the surface, and in contrast, there are no debonding of fiber in the new GFRP roof surface. It can be recommended that the exposed GFRP roof may be repaired to enhance its performance and can re-increase its properties using the coating.
