PRF Composite Materials releases new RP542-4 toughened prepreg system for UD and woven fabrics

We are delighted to introduce RP542-4, the latest epoxy prepreg system to be added to our innovative product range.

Designed as an intermediately toughened system – complimenting our RP542-1 and super-toughened RP549 systems – RP542-4 is producing excellent results on unidirectional and woven carbon fabrics.

Head of Technology, Heather Hughes, comments:

“The mechanical testing carried out shows the system to have excellent Tensile, Compressive, Flexural and Interlaminar properties and a relatively high Tg of 138°C after curing at 120°C. The onset Tg can be improved by 20°C to 120°C after post curing at 140°C for 2 hours. Adding to its usability, the system also has an out life of 60 days at 20°C.”
