Natural fiber reinforced biodegradable resin composites are expected to replace inorganic fiber reinforced thermosetting resin composites. Prediction of the mechanical properties of composites by using three material constants, fiber, matrix resin, interface is very important on the material design. In our previous study, Jute/PLA unidirectional specimen was fabricated by compression molding and bending test in 90 degrees direction was performed to evaluate the interfacial properties of continuous natural fiber reinforced composites. In this study, the fiber surface treatment was performed to improve the interfacial adhesion. By way of both 90 degrees bending test and FEM analysis, the interfacial strength between jute fiber and matrix was quantitatively calculated. Moreover, by using obtained material constants of interphase and weaving structural model, initial fracture stress of Jute/PLA flat braided composites was predicted.
