The aim of the Deliverable D7.5 is to demonstrate the solutions studied in the Deliverable D5.6 where post-consumer-based engineering compounds using polyamides components coming from End-Of-Life (EOL) vehicles have been produced. The demonstration performed in D7.5 has been started by the mechanical characterization and validation of the most common post-consumer material for the market, the polyamide 66 reinforced by 30% short glass fiber. To perform this, the activity has been performed in two main ways. The flexural tests on the demonstrative specimens, designed to reproduce the common effects observed in real components, have been performed and the simulations of the molding process with the structural behavior have been carried out. The results obtained from this campaign have been compared to the references; the first choice homologs materials produced using only virgin ingredients. After that, the furniture components have been selected to perform some preliminary functional tests by simulation tools. The recycled material considered is PA66-GF30. After that, the components have been produced by molding process where the engineering recycled polymer in shape of the granules has been transformed into component. To assess the properties at long-term usage, the fatigue tests of this material have been measured at two environmental conditions. The Wohler curves obtained for the recycled material have been compared to the reference one. Then, a simplified demonstration approach focused on the production process, has been followed to produce all selected components. To evaluate the performances, the process parameters normally used to treat the reference materials made of virgin ingredients, have been compared to the post-consumer ones. In this report, automotive, e-mobility components and consumer 3D printed goods have been produced.

Abstract
The aim of the Deliverable D7.5 is to demonstrate the solutions studied in the Deliverable D5.6 where post-consumer-based engineering compounds using polyamides components coming from End-Of-Life (EOL) vehicles have been produced. The demonstration performed in D7.5 has been started by the mechanical characterization and validation of the most common post-consumer material for the market, the polyamide 66 reinforced by 30% short glass fiber. To perform this, the activity has been performed in two main ways. The flexural tests on the demonstrative specimens, designed to reproduce the common effects observed in real components, have been performed and the simulations of the molding process with the structural behavior have been carried out. The results obtained from this campaign have been compared to the references; the first choice homologs materials produced using only virgin ingredients. After that, the furniture components have been selected to perform some preliminary functional tests by simulation tools. The recycled material considered is PA66-GF30. After that, the components have been produced by molding process where the engineering recycled polymer in shape of the granules has been transformed into component. To assess the properties at long-term usage, the fatigue tests of this material have been measured at two environmental conditions. The Wohler curves obtained for the recycled material have been compared to the reference one. Then, a simplified demonstration approach focused on the production process, has been followed to produce all selected components. To evaluate the performances, the process parameters normally used to treat the reference materials made of virgin ingredients, have been compared to the post-consumer ones. In this report, automotive, e-mobility components and consumer 3D printed goods have been produced. The economic and environmental studies performed on the techno-polymer value chain, have been also presented as well as the ICT platform. This latter present some scenarios of marketplace applied to the buying and selling of post-consumer materials (raw and finished ones).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
