There is growing concern about the environmental impact generated by key industrial sectors, especially in areas such as construction and mobility, where achieving materials with good mechanical performance, lighter weight, and greater fire resistance plays a crucial role.
In this context, AIMPLAS, the Plastics Technology Centre, is working on two projects funded by the Valencian Institute for Competitiveness and Innovation (IVACE+i), with support from the European Regional Development Fund (ERDF), to sustainably develop new flame-retardant coatings and composite materials that enhance safety in homes and transportation.
The main objective of the REFUGI project is to develop phosphorus-based flame retardants using mechanochemical processes, representing a step toward more environmentally friendly methods. These flame retardants are being integrated into varnish formulations specifically designed for use on wood. This strategy aims to improve the fire-resistant properties of coatings used in the construction sector.
Carolina Acosta, lead researcher in Mechanochemistry and Reactive Extrusion at AIMPLAS, explained: “The use of flame-retardant varnishes has increased in recent years, as they offer a finish virtually identical to any wood coating, with the added benefit of greater fire resistance, delaying its spread and effects in the event of a fire. We are focusing on exploring different material sources to produce these flame retardants, prioritising those that are renewable and recyclable.”
This research, carried out in collaboration with the companies Omar Coatings and Decomader, aims not only to improve the efficiency of flame-retardant production but also to reduce the environmental impact associated with their manufacture and application.
High-performance flame-retardant composite materials
The NEOCOMP project focuses on developing high-performance flame-retardant composite materials using advanced manufacturing technologies. This involves producing various parts through innovative industrial processes such as Dry Fibre Placement (DFP) and additive manufacturing. These composite materials must not only offer high performance in terms of mechanical strength, durability, and flame resistance but also significantly contribute to reducing the environmental impact in construction and mobility.
Specifically, it will develop flame-retardant thermoplastic binders for dry fibre, unidirectional dry fibre tapes for DFP, and continuously reinforced 3D filament. These new manufacturing approaches will enable the efficient production of preforms with complex geometries and the production of customised composite parts with improved mechanical properties, greater fatigue resistance, and excellent fire resistance. This will open new opportunities in sectors such as construction, automotive, and aerospace.
The companies Ziur Composites and IT3D are collaborating on this research, which aims to significantly reduce environmental impact and improve fire safety in critical mobility and construction infrastructures.
Both projects are part of the IVACE+i grant program for non-economic R&D projects carried out in collaboration with companies by technology centres in the Valencian Community for the year 2024, funded by the European Union's ERDF under the 2021–2027 Operational Program.
