Performance evaluation for composites based on recycled polypropylene using principal component analysis and cluster analysis

It is more economic and environmental-friendly to use recycled plastics in manufacturing, especially under the context of circular economy. Since there are many which formulae exist which improve the different properties of recycled plastics, there is a need to develop decision support tools for evaluating the materials based on multiple properties. In this study, principal component analysis (PCA) was used as a decision support tool to evaluate...
