PRF Composites, a manufacturer of high performance materials for the composites sector, has added the RP542-4, the epoxy prepreg system, to its product range. Designed as an intermediately toughened system, that goes well with the RP542-1 and super-toughened RP549 systems, RP542-4 is producing excellent results on unidirectional and woven carbon fabrics.

The system is available on 300 grams and 600 grams unidirectional carbon and our wide range of high quality woven fabrics in a variety of fibre types, the company said in a press release.

“The mechanical testing carried out shows the system to have excellent tensile, compressive, flexural and inter-laminar 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,” head of technology at the company, Heather Hughes said. (GK)
