PROMATAI project aims to develop a product in the field of testing the extrusion method of nanomaterials/bio(nano) composites using AI algorithms. Prototype will be developed and made of a special design for the Feed Opening Section (FOE), the Adjustable Groove Section (AGFS), the Rotary Barrel Section (RBS) and the additional Plasticizing System (PS) of the single-screw extruder, which will be tested in virtual and real conditions of their operation depending on the size of the introduced part. It is assumed that these improvements will increase the efficiency of the extrusion process, reducing the amount of waste and energy usage and enable usage of new materials. The first prototype in the world of a "smart extruder" is planned, which will adjust its geometric elements to the dimensions of the material. Project activities are aimed at significantly strengthening cooperation between industry and academia, creating new and transferring existing knowledge between partners. Project consists of 7 WPs: WP1-4 are focused on the development of innovative extruder elements, including: FOE, AGFS, RBS and the entire plasticizing system. WP5 focuses on networking activities conducted by delegations, including workshops, trainings, and lectures on the topic of the project and the development of skills in the field of R&D infrastructure, competences, digitization and internationalization. WP6 is about the wide dissemination of knowledge and the exploitation of project results (conferences, fairs, publications, IPR, website, social media, outreach to public activities), WP7 is about management and administration of the whole project. PROMATAI is coordinated by Łukasiewicz Research Network - Institute of Engineering of Polymer Materials and Dyes (Poland), partners are: Lublin University of Technology (Poland), Technical University of Kosice (Slovakia), University of West Attica (Greece), LPH a.s. (Slovakia), UAB Dirmeta (Lithuania) and Cerca Trova Ltd (Bulgaria).
