“…Kotaki et al [18] and Hojo et al [19] reported that the crack propagation behavior in FRP is strongly influenced by the interfacial bonding between fiber and matrix. Koiwa et al [20] introduced the measurement on the interfacial fracture toughness of Mode I and Mode II crack growth by using real size model composite. They reported a significant increase in fracture toughness with increasing bonding length.…”

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.

“…The crack propagation behavior on fiber-reinforced composites was strongly influenced by the interface between the fiber and the matrix as reported by Kotaki et al [38] and Hojo et al [39]. However, the evaluation of interfacial fracture toughness by using a real size composite model can be measured by Mode I/Mode II crack growth as examined by Koiwa et al [40], who reported that the increasing bonding length caused an improved interfacial fracture toughness. However, the results of the measurement of fracture toughness were obtained in a very short matrix size range.…”

The aim of this paper is to evaluate the Mode II interfacial fracture toughness and interfacial shear strength of Typha spp. fiber/PLLA and Typha spp. fiber/epoxy composite by using a double shear stress method with 3 fibers model composite. The surface condition of the fiber and crack propagation at the interface between the fiber and the matrix are observed by scanning electron microscope (SEM). Alkali treatment on Typha spp. fiber can make the fiber surface coarser, thus increasing the value of interfacial fracture toughness and interfacial shear strength. Typha spp. fiber/epoxy has a higher interfacial fracture value than that of Typha spp. fiber/PLLA. Interfacial fracture toughness on Typha spp. fiber/PLLA and Typha spp. fiber/epoxy composite model specimens were influenced by the matrix length, fiber spacing, fiber diameter and bonding area. Furthermore, the interfacial fracture toughness and the interfacial fracture shear stress of the composite model increased with the increasing duration of the surface treatment.
