This article features a large database on different extrusion processing conditions and the resulting tensile properties of poly(hydroxybutyrate--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. The data is also provided as support material for the research article: "Extrusion of wood fibre reinforced Poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) biocomposites: statistical analysis of the effect of processing conditions on mechanical performance" (Vandi et al., 2018).
本文介绍了一个大型数据库，该数据库涉及不同的挤出加工条件以及聚（3-羟基丁酸酯-3-羟基戊酸酯）（PHBV）和木纤维增强生物复合材料的拉伸性能。此处呈现的数据对应于分别针对纯PHBV聚合物和木材-PHBV复合材料进行的全面实验设计，其中研究了温度曲线、螺杆转速、进料速率、进料方式、螺杆构型以及10%、20%、30%和40%（重量）木材含量（仅针对木材-PHBV复合材料）的影响。对于每种加工条件，在单轴拉伸载荷下测试5个试样。在这里，我们提供了完整的挤出参数集，包括观察到的螺杆扭矩、停留时间和材料产量。提供了每个试样的单独应力-应变曲线，以及它们计算得出的弹性模量、强度和最大载荷下的应变。这些数据也作为研究文章《木纤维增强聚（3-羟基丁酸酯-共-3-羟基戊酸酯）（PHBV）生物复合材料的挤出：加工条件对机械性能影响的统计分析》（万迪等人，2018年）的支撑材料提供。
