In the article titled “Characterization of Rice Husk Fiber-Reinforced Polyvinyl Chloride Composites under Accelerated Simulated Soil Conditions” [1], the authors identified an error in the reported cut-off period, which should be corrected from 7 days to 30 days. Additionally, an error occurred in the process of exporting and drawing the infrared data, which led to an error in the 14-day aging time curve of Figure 3. The corrected Figure 3 is shown below.
The authors repeated the experiment to verify the conclusion, and the results are included in the supplementary materials.
A related article was not cited in the original publication. Article [1] used orthogonal experiments to determine the soil aging conditions and studied the performance changes before and after aging of rice husks (100 meshes) and PVC (100 meshes) composites. Article [2] focused on the optimization of rice husk/PVC formulations.
Since the second paper was an extension of the first paper, the authors compared the data from [1] to prove the conclusions. In article [2], the formula of MSRC was a particle size ratio of mixed-particle-size fibers of 80 : 120, mass ratio of mixed-particle-size fibers of 7 : 3, and mass ratio of wood-to-plastic of 4 : 6. The microstructure of RHRC (0 day and 21 days) shown in Figures 3(a) and 3(b) of article [2] corresponds to Figures 2(a) and 2(b) in article [1].
