POTENTIAL OF LOCAL FAST-GROWING WOOD FOR ALTERNATIVEHULL MATERIALS: EPOXY BOND STRENGTH TEST AND ITSDURABILITYFakhri, Imam Suprayogi, Yusni Ikhwan Siregar,Sujianto and Tibertius Agus PrayitnoAbstract It has been claimed that wood species suitable for wooden boat is decreasing fast. Boat maker has beenhardly looking for wood species for traditional wooden boat. In order to find potential wood species forwooden boat production, this research was conducted. The objectives of the research was to obtain theepoxy wood bonding behavior of several wood species. Eight wood species were procured form Pekanbaru,Riau. They were glued by epoxy with three glued spread. The bonding durability was tested by cyclicboiling test. It was concluded that dry epoxy bonding strength of behaved differently than wet epoxybonding strength. The dry epoxy bond strength is influenced by wood species factor and glue spread.Jabon show the highest dry strength of 436 kg/cm2, while the lowest is shown by trembesi species. Lowglue spread of 30#/MSGL produced highest bond strength. The glue spread showed negative correlationto bond strength. Wet strength is affected by interaction of wood species and glue spread factor. The highestwet strength (44kg/cm2) is shown by mahang species combined with 50 pound/MSGL glue spread. |
