PRF Composite Materials is delighted to introduce RP542-4, the latest epoxy prepreg system to be added to its innovative product range.

Designed as an intermediately toughened system, complementing both the company’s 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.”

The system is available on 300gsm and 600gsm unidirectional carbon and PRF’s wide range of high quality woven fabrics in a variety of fibre types.
