Extrusion processing and tensile properties of Poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and wood fibre reinforced PHBV biocomposites

The data provided here is a large database on different extrusion processing conditions and the resulting tensile properties of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and wood fibre reinforced biocomposites. The data presented here corresponds to a comprehensive design of experiments conducted separately for both neat PHBV polymer and wood-PHBV composites, in which the effects of temperature profile, screw speed, feeding rate, feeding method, screw configuration, and wood contents (wood-PHBV composites only) of 10 , 20 , 30 , and 40 wt% wood content were examined. For each processing condition, 5 specimens were tested under uniaxial tensile loading. Here we provide the complete set of extrusion parameters, including the observed screw torque, residence time and material output. Individual stress-strain curves for each specimens are provided, along with their calculated elastic modulus, strength, and strain at maximum load.
