The next decisive step in the production of large-scale structural components from thermoplastic composites for aerospace has been achieved, says Victrex, a provider of high-performance polymer solutions
.
Using its enhanced Automated Fiber Placement (AFP) process technology, Electroimpact, an experienced factory automation and tooling solutions provider, is able to increase thermoplastic unidirectional tape (TP UDT) placement speeds to 4,000 inches per minute ( IMP)
.
Currently, large composite structures in aerospace, such as wings and fuselages, are actually based on thermosets
.
As sustainability becomes an important driver in the aerospace industry, OEMs and all segments are looking to improve not only the fuel efficiency of aircraft, but the efficiency of the entire supply chain
.
“We know for the first time that the importance of processing thermoplastic UDT at 4,000 IPM layup speeds with a variable spot size (VSS) laser is that thermoplastics can achieve thermoset layup speeds
.
By deploying a new laser heating system, Electroimpact enhances existing AFP processing technology and has the potential to transform heat treatment processes in the aerospace industry
.
Assadi added: “We are delighted to offer this new laser technology and the wider use of Victrex’s high-performance LMPAEK composites to address unmet customer needs
.
Electroimpact has gone one step further and conducted field production trials with the VICTREX AE 250 UDT

VICTREX AE 250 LMPAEK UDT: Efficient production combined on-site and off-autoclave
VICTREX AE 250 LMPAEK UDT: Efficient production combined on-site and off-autoclaveKey to the collaboration is the joint offer to optimise the AFP process, which offers considerable time and energy savings in both in-situ and autoclave (OoA) consolidation compared to another polyketone UD tape for similar applications
.
VICTREX AE 250 UDT is a new high performance thermoplastic composite prepreg tape designed by Victrex with mechanical, physical and chemical resistance typical of PAEK polymer families such as PEEK, but at 40°C (104°F) ) lower crystal melting temperature, only 305°C (581°F)
