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.

本数据集包含了一项关于不同挤出加工条件下聚（羟基丁酸-羟基戊酸）(PHBV)及其木质纤维增强生物复合材料拉伸性能的大型数据库。所提供的数据对应于针对纯PHBV聚合物和木-PHBV复合材料分别进行的全面实验设计，其中考察了温度曲线、螺杆转速、进料速率、进料方式、螺杆配置以及木材含量（仅限于木-PHBV复合材料）对10%、20%、30%和40%木材含量的影响。对于每种加工条件，均进行了5个试样的单轴拉伸测试。在此，我们提供了完整的挤出参数，包括观察到的螺杆扭矩、停留时间和材料输出。每个试样的应力-应变曲线均提供，并附有其计算的弹性模量、强度和最大载荷时的应变。
