Mechanical properties of polylactic acid (PLA) composites reinforced with unidirectional flax and flax-paper layers
Source abstract
Abstract
Abstract Natural fibers are gaining much interest in composite materials because of their potential to replace conventional glass fibers. In particular, unidirectional flax fiber composites have shown excellent mechanical properties with different thermoset matrices. However, few data are available when they are made with a biodegradable thermoplastic matrix. This paper compares the mechanical properties of two types of unidirectional flax composites using polylactic acid as the matrix: one made with layers of aligned flax rovings alone and the other containing an additional paper layer fabricated using paper making techniques. The results show that specific tensile properties of the flax/PLA (252 MPa·cm3·g−1) and flax-paper/PLA (217 MPa·cm3·g−1 ) composites are similar to those made using woven glass fabrics impregnated with epoxy (227–278 MPa·cm3·g−1). Very high impact strength (600 J/m) was also obtained for UD flax-paper composites compared to unreinforced resin (15 J/m). Together these mechanical properties are promising for industrial applications of this new reinforcement.
