As part of the regional NEOCOMP project, funded by IVACE in the Valencian Community, AIMPLAS presents a comprehensive approach to the development of advanced composite materials by producing dry fiber through its own pilot line. This work focuses on the development of thermoplastic binders, dry fiber production, pre-consolidation and resin infusion, as well as the study of mechanical properties. The main objective is the development of thermoplastic binders and the subsequent production of dry fiber. The binders will be formulated using compounding technologies with co-rotating twin-screw extruders to ensure proper dispersion and distribution of the additives. The dry fiber will be produced using a pilot plant system designed and developed by AIMPLAS, equipped with the necessary technology for binder adhesion onto continuous reinforcement. Finally, the materials will be validated for processing with AFP (Automated Fiber Placement) equipment to achieve pre-consolidated panels. After pre-consolidation, resin infusion will be carried out to obtain high-performance structural materials. The binder materials will be characterized through powder granulometry analysis, while the dry fiber will be studied using scanning electron microscopy (SEM) to evaluate binder-to-fiber distribution and adhesion. The project concludes with a thorough tensile analysis of the infused panels, following standards for mechanical performance evaluation. The results obtained not only highlight the potential of the developed materials but also demonstrate the feasibility of this approach for the industrial production of high-performance composite materials for key sectors such as aerospace.
