Polymer and Composites Technology
The overall objective is to create and transfer the knowledge on composite-intensive primary structures that meet weight, cost and production rate requirements. The activity is organized around three research domains:
1) Advanced Resin Transfer Moulding (RTM); Thermoplastic RTM (TP-RTM), Compression RTM (CRTM), Fibre Metal Laminate RTM (FML-RTM).
2) Ultraviolet curing technology applied to; Pultrusion, Automatic Tape Laying (ATL), Filament Winding.
3) Deformation and fracture of polymer and composites; Stamp forming, Impact/damage simulation, Morphing.
In PKT emphasis is placed on application-oriented research and the development of products to pilot production level. Automotive (PSA-Citröen, CIDIA), Railway (CAF), Civil Engineering (Acciona Infraestructuras, ULMA Construcción), Tooling Machine (Danobat, Trimek) and Sport (Orbea) are some of the most representative industrial partners.
PKT has state-of-the-art technology and equipment to meet the needs of application oriented research and development.
Training of young researchers (undergraduates and doctorates) and professionals form the industry is also a nuclear activity of the research group.
