Abstract

In the field of biocomposites, there are many different methods when it comes to technical evaluation. Standardized key figures and failure criteria used by researchers and practitioners worldwide often lead to limited results and contradictory statements. For the decision-maker, this makes a comprehensive evaluation for a qualitative material selection challenging. The novelty of the principle presented in this study is the incorporation of stand-alone techniques for technical assessment into a holistic procedure based on fracture analytical value analysis. For this purpose, appropriate safety indicators were created to enable large-scale assessments of bio-based composites. Experimental investigations on extruded fiber- and particle-based HDPE polymeric green composites demonstrate the efficacy of both generated safety parameters and evaluation process, respectively. Finally, a peer-group review of comparable investigations was conducted to find best practices for selection support.
