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.
“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,” stated head of technology, Heather Hughes. “The onset Tg can be improved by 20°C to 120°C after post curing at 140°C for two 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 quality woven fabrics in a variety of fibre types.
