Abstract
In this study, poly(lactic acid) (PLA) matrix bio-composites reinforced with various quantities of sisal fibers (SFs) (from 10% to 50% in weight) were fabricated by using a self-made vane mixer, which can generate continuous elongation flow. The morphology, crystallization, and mechanical properties of PLA/SF bio-composites under continuous elongation flow were investigated. Scanning electron microscopic images showed that SFs were uniformly dispersed in the matrix and oriented along the extrusion direction. Meanwhile, it was found that the diameter of SFs decreased from 250 to 20 μm, which certified that continuous elongation flow remarkably affected the separation of elementary fibers from fiber bundles. Wide-angle X-ray diffraction and differential scanning calorimetry measurements indicated that the addition of SFs promoted the crystallization of PLA as well as increased the crystallinity of PLA. The mechanical tests exhibited that both impact strength and tensile modulus were significantly enhanced (about 64% and 94.63%, respectively) with SFs loading at 40%, which was due to the well dispersion and separation of elementary fibers.
