ABSTRACT: In this
work, interfacial fracture toughness between treated fiber and matrix was
investigated by using double shear test method. Susrface treatment on the oil
palm empty fruit bunch (OPEFB) fibers was performed to improve the interfacial
bosnding properties of natural fiber reinforced Poly(L-lactide acid)
composites. Three fibers model composite and four fibers model composite were
prepared for the double shear test. The interfacial fracture toughness of both
model composites is dependent on matrix length. In addition, the interfacial fracture
toughness and the critical interfacial shear stress were increased with
increasing the concentration of NaOH and the duration of surface treatment.
