Rheology studies of multiple times processed poly(lactic acid)-carbon black composites

This dataset contains MFR/MVR (melt flow rate) rheology studies of commercially available ProtoPasta 3D printable filament, composed of poly-lactic acid (PLA) and conductive carbon black (CB) filler. The study aims to observe structural differences and applied properties changes under multiple reprocessing of the composite material at different temperatures (190 and 200 C). X informs about the number of reprocessing events.
These results are part of the manuscript published in Materials (https://www.mdpi.com/1996-1944/16/3/1307). The aim of this research was to understand the degradation process and utility of materials after multiple reprocessing times.

本数据集包含市售ProtoPasta品牌3D打印耗材的熔体流动速率/熔体体积流动速率（MFR/MVR）流变学研究数据，该耗材由聚乳酸（PLA）与导电炭黑（CB）填料复合制成。本研究旨在观测该复合材料在190℃与200℃下多次再加工过程中的结构差异与应用性能变化，其中X用于表征再加工次数。
本研究结果已发表于《Materials》期刊（https://www.mdpi.com/1996-1944/16/3/1307）。本研究旨在探明该复合材料经多次再加工后的降解过程与使用性能。
