mm/min. The residual poly(lactic acid) resin on the fracture surface of a single flax yarn reinforced biocomposite material using poly(lactic acid) resin was found after tensile test at all loading speed conditions. But the large fiber pullout on fracture morphology of single flax yarn reinforced biocomposite material using shellac resin was noticeably found after tensile test at 100 mm/min. Therefore, tensile property of a single flax yarn reinforced biocomposite material was mainly affected by adhesion and tensile properties of matrices under loading speed. References 1.
