摘      要：Thailand has a huge variability of bast fiber plants,some of which have been little researched regarding their applicability in *** fiber(bundle)s from different species were investigated and incorporated into a polylactide(PLA)matrix by injection *** and kenaf were used as well-studied fibers,while roselle,Fryxell and paper mulberry are less extensively *** strength,tensile modulus and interfacial shear strength(IFSS)of single fiber(bundle)s were highest for hemp,followed by kenaf,roselle,Fryxell and paper *** the lower tensile strength and IFSS of paper mulberry,the highest tensile strength was achieved for the paper mulberry/PLA composite followed by hemp/*** electron microscope(SEM)analyses showed that the single cells in paper mulberry fiber bundles,in contrast to the other fiber types investigated,were only partially bonded to each other,which explains the lower strength of the fiber *** higher aspect ratio of fiber(bundle)s of paper mulberry in the PLA composite can explain the good composite *** from hemp,paper mulberry shows the best reinforcing effect in the PLA matrix and offers interesting potential for composite *** to neat PLA,the tensile strength could be increased by 24%and the tensile modulus by 54%.
