摘要：The objective of this research is to determine the epoxy matrix ability in wetting a king pineappleleaf fiber (Agave cantala Roxb) and the epoxy matrix bonding ability to a pineapple leaf fibers king(KPLF) as a result of the fiber fumigation treated. The droplet contact angle testing is the way tofind out the fiber wettability. Measuring the contact angle is a simple method to determine theinterface compatibility of two interlocked surfaces. The contact angle between the epoxy matrixesand the KPLF measurement was performed with a Mitutoyo digital microscope and analyzed bythe Image Pro software. KPLF without and with fumigation treatment was observed by SEM todetermine the ability of KPLF interlock with the epoxy matrix. The measurement result shows theeffect of KPLF fumigation toward the fiber wettability. The epoxy matrix droplets on the KPLFsurface has a contact angle of less than 30o, which means that the epoxy matrix has a good abilityin wetting the KPLF fiber surface and would affect to the interlock ability between the KPLF andepoxy matrix. The interface shear stress (IFSS) matrix epoxy with KPLF increased by 282.8 % forthe fiber fumigated for 15 hours.
