In this paper a composite prepreg manufactured using a relatively new high performance PAEK (polyaryletherketone) polymer from Victrex will be described, which offers out of autoclave (OoA) processing at lower temperatures than Polyetheretherketone (PEEK) and polyetherketoneketone (PEKK) whilst displaying excellent consolidation with minimal voids and good mechanical properties.
Coriolis Composites and Victrex teamed up to design an Automated Fibre Placement (AFP) process to unlock the potential of VICTREX AE™ 250 UDT. The results showed a significant increase in lay-up speed was possible whilst achieving industry acceptable levels of porosity (<2%) for in-situ consolidation. OoA consolidation showed the potential to reduce the cycle time and energy consumption.
The paper presents material behavior and the development of simulation methods for modeling a hybrid system. The results present test data and simulation results for both plaques and a bracket constructed using the hybrid molding technology.
The whitepaper covers how adaptation of existing PEEK-based sealing, isolation, and compression technologies is anticipated to be a practical means to realize the energy transition to hydrogen on an accelerated timeline.
This paper discusses the importance of looking beyond the minimum requirements of standard test protocols to better understand performance in harsh environments, and what data you should be asking for from your material or shapes suppliers.
