Erratum to: Mechanical and Impact Properties of PLA/2 × 2 Twill and 4 × 4 Hopsack Weave Flax Textile Composites Produced by the Interval Hot Pressing Technique

Abstract

Polylactide (PLA)/2 × 2 twill and 4 × 4 hopsack weave flax textile composites were produced by the interval hot pressing technique. The dispersion of structural elements of the composites was inspected by the scanning electron microscopy (SEM). The composites were subjected to instrumented falling-weight impact tests. Their mechanical properties (tensile strength and stiffness) were determined in tensile and dynamic mechanical thermal tests. The SEM showed that the interfacial gaps around pulled-out fibers diminished when the interval hot pressing was used. It was also found that both the types of flax composites had a higher impact resistance than the neat PLA. The tensile strength and stiffness of the PLA/flax composites were also markedly higher than those of PLA and reflected the effect of their structures. The storage creep compliance was determined by using the relations of linear viscoelastic materials and the time-temperature superposition principle. The calculated creep response of the flax composites was much lower than that of the neat PLA.
